Within the Cisco IOS software documentation, the term router is used to refer to both access servers and routers. When a feature is supported on the access server only, the term access server is used. When a feature is supported on one or more specific router platforms (such as the Cisco 4500), but not on other platforms (such as the Cisco 2500), the text specifies the supported platforms.
Within examples, routers and access servers are alternately shown. These products are used only for example purposes--an example that shows one product does not indicate that the other product is not supported.
To assign a called party number to a particular modem pool, use the called-number modem pool configuration command.
called-number number [max-conn number]| number | Called number for a specified modem pool. |
| max-conn number | (Optional) Maximum number of simultaneous connections allowed for the called party number. |

Modem pool configuration
This command first appeared in Cisco IOS Release 11.2 P.
For a general description of modem pools and how they are configured on Cisco access servers, see the command reference page for the modem-pool command.
The called party number, which is configured with the called-number command, is based on the dialed number identification service (DNIS). You can also configure multiple called numbers or DNIS for a single modem pool, as shown in the "Examples" section.
Use the max-conn option if you want to specify a maximum number of modems or analog connections that a called party number can use. For example, if you create one modem pool to serve two or more customers, this option sets limits on how many maximum connections each customer can have in to the modem pool. In this way, one customer cannot occupy or monopolize an entire modem pool. Essentially, this feature provides overflow protection and sets dial-in limits for individual customers.
The Cisco IOS software also includes a feature that simplifies the called number configuration. By using an x variable as the last digit in a called telephone number (for example, issuing the called-number 408555121x command), clients dialing different called numbers such as 4085551214 or 4085551215 will automatically be mapped to the same modem pool. The x variable is a place holder for the digits 1 through 9.
In the following example, the pool-range command assigns modems 1 to 59 to the modem pool called accounts1. The called-number 4085551212 max-conn 30 command assigns the called number 4085551212 to the accounts1 modem pool. The total number of simultaneous connections are limited to 30. The called-number 4084441212 max-conn 30 command assigns the called number 4084441212, which is for a different customer, to the same accounts1 modem pool. The total number of simultaneous connections for this called number is also set to 30. This configuration guarantees a maximum of 30 modems to each customer and protects each customer from unwanted modem calls overflowing in to their respective pools.

To customize E1 R2 signaling parameters for a particular E1 channel group on a channelized E1 line, use the cas-custom controller configuration command.
cas-custom channel| channel | Specifies a single channel group number, which can be between 0 and 30. This channel group number must match the channel number specified in the cas-group command. |
No customized signaling parameters are set. If you do not specify a country name using the country name command, which is described in Table 1, ITU is the selected default signal.
Controller configuration
This command first appeared in Cisco IOS Release 11.2 P.
The customization parameters set by the cas-custom channel command are applied to the same channel group number used in the cas-group channel timeslots range type signal command. These channel group numbers must match. Otherwise, the customized features specified by the cas-custom command will not be applied to the cas-group command's configuration. The signaling customization will not take effect. See Example 1.
However, you will not need to configure or set more than one channel group number per E1 line in most cases. Though rarely used, it is possible to split a single E1 (timeslots 1 to 31) into two groups (for example, 1 to 15 on group 1 and timeslots 17 to 31 in group 2).
Cisco strongly recommends that you use the use-defaults option when specifying a particular country type. See the country name command in Table 1. This additional keyword ensures that all the local country settings are correctly enabled. For example, issue the country greece use-defaults command. If the use-defaults option is not specified, generic ITU will be the default setting for all countries. See Example 2.
You can configure the system to deviate from a country's default settings as defined by Cisco. To do this, choose from the following list of commands described in Table 1: answer-signal {group-a | group-b} number, caller-digits number, category number, dnis-digits number, invert-abcd, ka number, kd number, metering, nc-congestion, and unused-abcd value. To return a country back to its country specific default settings, issue the country name use-defaults command. To return a country back to the ITU standard, issue the default country name use-defaults command. See Example 3 and Example 4.
Table 1 shows a list of command options in cas-custom mode, which is used to customize R2 signaling settings.
| CAS Custom Command | Purpose |
|---|---|
| answer-signal {group-a | group-b} number | Answer signal to be used. You can specify the group A signal or the group B signal. The signal number can be 1 to 15. Default is group-b 6, which is the ITU default. |
| caller-digits number | Specifies the number of digits the access server needs to collect before it requests ANI or CallerID information. The digits can be from 1 to 10. Default is 1, which is the ITU default. |
| category number | Specifies the type of incoming call, which is mapped to a group signal number. Signal numbers from 1 to 15 are available. Default is 1, which is the ITU default. |
| country name | Specifies local country settings to use with R2 signaling. Replace the name variable with one of the following supported country names. Cisco strongly recommends that you include the use-defaults option, which enables the default settings for a specific country. Default country setting is ITU.

default | Sets a command to its default setting. |
| dnis-digits number | Expected number of DNIS digits. You can specify 1 to 64 digits. Default is 0, which is the ITU default. |
| exit | Takes you out of cas custom mode. |
| invert-abcd | Inverts the ABCD bits before tx and after rx. This feature is disabled by default, which is the ITU default. |
| ka number | Specifies the KA signal code. You can choose 1 to 15. Default is 0, which is the ITU default. |
| kd number | Specifies the KD signal code. You can choose 1 to 15. Default is 0, which is the ITU default. |
| metering | Specifies sending a metering pulse when the access server is making an outgoing call. Metering is turned off by default, which is the ITU default. |
| nc-congestion | Specifies the non-compelled congestion signal. This signal is sent to the central office when the access server is congested and cannot accept the call. The default is B4, which is the ITU default. |
| no | Negates a command or sets its defaults. |
| unused-abcd value | Specifies unused ABCD bit values, which can have a 0 or 1 bit value. This feature is disabled by default, which is the ITU default. |
The following example displays the available signaling parameters after you enter cas-custom mode. Notice that the same channel group 1 is specified in the cas-group command and the cas-custom command.

You can localize your R2 configuration for a specific country. Don't forget to include the use-defaults option as described in Table 1. For example, use the country argentina use-defaults command for a R2 scenario in Argentina.
router(config-ctrl-cas)#country ?argentina Argentina australia Australia brazil Brazil china China columbia Columbia costarica Costa Rica easteurope East Europe ecuador-itu Ecuador ITU ecuador-lme Ecuador LME greece Greece guatemala Guatemala hongkong-china Hong Kong (China variant) indonesia Indonesia israel Israel itu ITU korea Korea malaysia Malaysia newzealand New Zealand paraguay Paraguay peru Peru philippines Philippines saudiarabia Saudi Arabia singapore Singapore southafrica-panaftel South Africa Panaftel telmex Telmex telnor Telnor thailand Thailand uruguay Uruguay venezuela Venezuela vietnam Vietnam router(config-ctrl-cas)# country argentina ? use-defaults Use Country defaults <cr> router(config-ctrl-cas)#country argentina use-defaults
The following example customizes the signaling for channel group 1. The configuration collects 3 digits before it requests ANI information for analog calls received on a Cisco AS5300 in Argentina.
router(config-controller)#cas-custom 1router(config-ctrl-cas)#country argentina use-defaultsrouter(config-ctrl-cas)#caller-digits 3router(config-controller)#^zrouter(config)#
Since cas-custom mode gives you the flexibility to customize R2 parameters, the margin for user error increases. Therefore, the Cisco IOS software enables you to return a country back to its default R2 settings using the use-defaults option. The following example begins by bringing up Argentina's default settings, changing a few customization parameters, then returning the Argentina R2 setting back to its original state.

cas-group (controller E1)
To configure channel associated signaling on an E1 controller, use the cas-group controller configuration command. Use the no form of this command to disable channel associated signaling for one or more timeslots.
cas-group channel timeslots range type signal| channel | Specifies a single channel group number. Replace the channel variable with a number between 0 and 30. |
| timeslots range | Specifies a timeslot range, which can be from 1 to 31. You can specify a timeslot range (for example, 1-31), individual timeslots separated by commas (for example 1, 3, 5), or a combination of the two (for example 1-7, 8, 17-31). The 16th time slot is reserved for out-of-band signaling. |
| type signal | Specifies the type of channel associated signaling. Configure the signal type that your central office uses. Replace the signal variable with one of the following signal types:
· e&m-fgb [dtmf [dnis] | mf [dnis]]--Specifies ear and mouth channel signaling with feature group B support, which is includes the wink start protocol. The optional signal tones are DTMF and MF with the option of provisioning DNIS. · e&m-fgd--Specifies ear and mouth channel signaling with feature group D support, which is includes the wink start protocol. · e&m-immediate-start--Specifies ear and mouth channel signaling with immediate start support. · fxs-ground-start--Specifies foreign exchange system ground start signaling support. · fxs-loop-start-- Specifies foreign exchange system loopstart signaling support. · p7-- Specifies the P7 switch type. · sas-ground-start--Specifies specific access station ground start signaling support. · sas-loop-start--Specifies specific access station loopstart signaling support. |
| · r2-analog [dtmf | r2-compelled [ani] | r2-non-compelled [ani] | r2-semi-compelled [ani]]
· r2-digital [dtmf | r2-compelled [ani] | r2-non-compelled [ani] | r2-semi-compelled [ani]] · r2-pulse [dtmf | r2-compelled [ani] | r2-non-compelled [ani] | r2-semi-compelled [ani]] | |
| The following descriptions are provided for the previous three R2 syntax bullets:
r2-analog--Specifies R2 ITU Q411 analog line signaling, which reflects the on/off switching of a tone in frequency division multiplexing circuits (before TDM circuits were created). The tone is used for line signaling. r2-digital--Specifies R2 ITU Q421 digital line signaling, which is the most common signaling configuration. The A and B bits are used for line signaling. r2-pulse--Specifies R2 ITU supplement 7 pulse line signaling, which is a transmitted pulse that indicates a change in the line state. dtmf--Specifies the DTMF tone signaling. r2-compelled [ani]--Specifies R2 compelled register signaling. You can also specify provisioning the ANI addr option. r2-non-compelled [ani]--Specifies R2 non compelled register signaling.
|
No channel associated signaling is configured on the controller. All R2 signaling types have DNIS turned on by default.
Controller configuration
This command first appeared in Cisco IOS Release 11.2 P.
Use this command to configure support for incoming and outgoing call signals (such as on-hook and off-hook) on each E1 controller.
If you specify the timeslot range 1-31, the system software automatically uses the 16th timeslot to transmit the channel associated signaling.
The signaling you configure on the access server must match the signaling used by the central office. For example if the central office switch is forwarding R2 analog signaling to a Cisco AS5300, then the access server's E1 controller must also be configured for R2 analog signaling (r2-analog).
All R2 signaling options have DNIS support turned on by default. If you enable the ani option, the collection of DNIS information is still performed. Specifying the ani option does not disable DNIS. DNIS is the number being called. ANI is the caller's number. For example, if you are configuring router A to call router B. Then the DNIS number is router B. The ANI number is router A. ANI is very similar to Caller ID.
To customize the R2 signaling parameters, refer to the cas-custom controller configuration command. When you enable the cas-group command, the cas-custom command is automatically setup to be polled for configuration information. However, unless you enable or turn on specific features with the cas-custom command, the cas-custom feature has an empty set of signaling parameters.
DNIS is automatically collected for modem pools and R2 tone signaling. You do not need to specify the collection of DNIS information with the cas-group command. However, if you are using non-R2 tone signalling, the system must be manually configured to collect DNIS information. For non-R2 cas signalling, DNIS collection is done only for E&M-fgb.
In most cases, you will configure the same channel associated signaling on each E1 controller. The following examples configure signaling and customized parameters on controller E1 2 using the cas-group and cas-custom controller configuration commands.
The actual channel associated signaling is configured on the 16th timeslot, which is the reason why this timeslot does not come up in the following output.

To configure channelized T1 timeslots with robbed bit signaling, use the cas-group controller configuration command. Use the no form of this command to disable channel associated signaling for one or more timeslots.
cas-group channel timeslots range type signal| channel | Specifies a single channel group number, which can be between 0 and 23. |
| timeslots range | Specifies a timeslot range of values from 1 to 24. |
| type signal | Specifies the type of robbed bit signaling. Choose one of the following signal types to configure:
· e&m-fgb [dtmf [dnis] | mf [dnis]]--Specifies ear and mouth channel signaling with feature group B support, which includes the wink start protocol. You can further customize this feature by specifying dtmf [dnis] or mf [dins]. · e&m-fgd--Specifies ear and mouth channel signaling with feature group D support, which includes the wink start protocol. · e&m-immediate-start--Specifies ear and mouth channel signaling with immediate start support. · fxs-loop-start-- Specifies Foreign Exchange Station loopstart signaling support. · fxs-ground-start--Specifies Foreign Exchange Station ground start signaling support. · sas-loop-start--Specifies Special Access Station loopstart signaling support. · sas-ground-start--Specifies Special Access Station ground start signaling support. |
If the cas-group command is enabled, the default signal is E&M feature group B.
Controller configuration
This command first appeared in Cisco IOS Release 11.2.
Use this command to enable an integrated modem to receive and transmit incoming and outgoing call signaling (such as on-hook and off-hook) through each T1 controller.
If you want to collect DNIS information on a T1 controller, you must manually configure it on the access server. DNIS collection is performed only for E&M-fgb. To collect DTMF DNIS for E&M-fgb under a controller T1 configuration, issue the cas-group 0 timeslots 1-24 type e&m-fgb dtmf dnis command. To collect MF DNIS for E&M-fgb, issue the cas-group 0 timeslots 1-24 type e&m-fgb mf dnis command.
The following example configures all 24 channels with ear and mouth robbed bit signaling with feature group B support:

The following example configures the required signaling to support modem pooling and the digital number identification service (DNIS) over channelized T1 lines on a Cisco AS5300. Supported tones types and signaling include E & M feature group B, DTMF tones, and MF tones. By configuring DNIS as part of the cas-group command, the system can collect DNIS digits for incoming calls, which can be redirected to specific modem pools setup for different customers or uses. Additionally, you must be running MICA modems in the system and have at least 10% of your total modems in the default modem pool. Free modems are needed in the default pool to detect the incoming called number or DNIS before handing the call off to the appropriate modem pool. Therefore, two modems are actually needed to handle one incoming call that is destined for a modem pool.

To copy bundled modem firmware from a Cisco IOS system image loaded in system Flash memory, use the copy ios-bundled modem EXEC command.
copy ios-bundled modemThis command has no additional keywords or arguments.
Disabled
EXEC
This command first appeared in Release 11.2 P.
This command does not overwrite or delete any existing modem code files that reside in your system Flash memory. If you decide to delete the firmware files from system memory, remember that all files in system Flash memory will be deleted. Individual files cannot be individually deleted. Therefore backup any important files such as your Cisco IOS software image.
The following example downloads modem firmware that is bundled with the Cisco IOS software image to modems 1/0 through 1/23.
Step 1 Enter the copy ios-bundled modem EXEC command:
copy ios-bundled modem
Step 2 Specify the modem or range of modems that you want to receive the firmware. This example copies the firmware to modems 1/0 through 1/23.
1/0-1/23
Step 3 Specify whether you want the update to occur instantaneously or during the next system reload. The busyout option downloads the firmware as soon as the modem(s) becomes available. If the modem is idle when the command is executed, the firmware is downloaded immediately. The reboot option stores instructions in the NVRAM table and downloads the firmware from the Cisco IOS system image during the next system reload.
busyout
Step 4 Confirm the copy operation by answering yes:
yes
The following example updates modem firmware at the next system reload:

To configure duplex mode on a Fast Ethernet interface, use the duplex interface configuration command. Use the no form of this command to return the system to half duplex mode, which is the system default.
duplex {full | half | auto}| full | Specifies full duplex configuration. |
| half | Specifies half duplex configuration. |
| auto | Specifies the auto negotiation capability. The interface automatically operates at half or full duplex, depending on environmental factors, such as the type of media and transmission speeds for the peer routers, hubs, and switches used in the network configuration. |
Half duplex mode
Interface configuration
This command first appeared in Cisco IOS Release 11.2 P.
The auto negotiation capability is turned on for the Fast Ethernet interface by either configuring the speed auto command or the duplex auto command.
Table 2 describes the system's performance for different duplex and speed configuration combinations. Reading across one row at a time, the specified duplex command configured with the specified speed command produces the resulting system action.
| Duplex Command | Speed Command | Resulting System Action |
|---|---|---|
| duplex auto | speed auto | Auto negotiates both speed and duplex modes. |
| duplex auto | speed 100 or speed 10 | Auto negotiates both speed and duplex modes. |
| duplex half or duplex full | speed auto | Auto negotiates both speed and duplex modes. |
| duplex half | speed 10 | Forces 10 Mbps and half duplex. |
| duplex full | speed 10 | Forces 10 Mbps and full duplex. |
| duplex half | speed 100 | Forces 100 Mbps and half duplex. |
| duplex full | speed 100 | Forces 100 Mbps and full duplex. |
The duplex {full | half | auto} command syntax replaces the following two earlier duplex commands:
The following error messages appear if you try to use these deprecated commands:
router(config)#interface fastethernet 0router(config-if)#full-duplexPlease use duplex command to configure duplex mode router(config-if)# router(config-if)#half-duplexPlease use duplex command to configure duplex mode

To create or specify a modem pool, use the modem-pool global configuration command.
modem-pool name| name | Specifies the name for a particular modem pool. |
All modems are configured to be part of one system default modem pool. If you have 120 MICA modems loaded in your system, then 120 modems are in the default modem pool.
Global configuration
This command was first introduced in Cisco IOS Release 11.2 P.
Modem pooling allows service providers to define, select, and use separate pools of modems within a single access server to enable different dial-in services for different services. See Table 3 and Figure 1.
| DNIS or Called Number | Maximum Number of Customer Ports | Service |
|---|---|---|
| 555-4444 | X | Wholesale customer A, guaranteed ports, 56K modems |
| 555-3333 | Y | Wholesale customer B, guaranteed ports, Fax modems |
| 555-5555 | Z | Retail service port allocation and/or overflow for wholesale service A |
| Any other | Remaining | Default pool, used for other purposes |
Total ports = X + Y + Z + remaining
The goal of the configuration in Table 3 is to guarantee all customers a minimum number of available connections. After customers reach their minimum number of guaranteed connections, they get a busy signal. For example, suppose all X customers dial in to 555-4444 and gain access. When the X +1 customer dials in to 555-4444, that customer receives a busy signal, assuming that the DNIS 555-4444 is configured for a maximum number of connections. (See the called-number command.) Though customer X + 1 gets a busy signal, customer Y can successfully dial in to 555-3333 and gain access. Customer Y gets access because the called number 555-3333 has its own private range of modems.
You can view the actual configuration information for Figure 1 by entering the show modem-pool command:
router# show modem-pool
modem-pool: System-def-Mpool
modems in pool: 20 active conn: 0
0 no free modems in pool
modem-pool: accounts1
modems in pool: 50 active conn: 0
0 no free modems in pool
called_party_number: 1000
max conn allowed: 25, active conn: 0
0 max-conn exceeded, 0 no free modems in pool
called_party_number: 2000
max conn allowed: 25, active conn: 0
0 max-conn exceeded, 0 no free modems in pool

0 max-conn exceeded, 0 no free modems in pool
called_party_number: 4000
max conn allowed: 25, active conn: 0
0 max-conn exceeded, 0 no free modems in pool
The following example creates a new modem pool called accounts1. After you specify the modem pool name, your system software automatically takes you to modem pool configuration mode. Notice that the router prompt changes from router(config)# to router(config-modem-pool)#.
router#configure terminalEnter configuration commands, one per line. End with CNTL/Z. router(config)#modem-pool accounts1router(config-modem-pool)#
The next example assigns modem TTY line numbers 30 to 50 to the modem pool accounts1. The modem pool's called number is set to 2000. The customers dialing 2000 are guaranteed access to 21 modems. The 22nd client to dial in will be refused connectivity because the maximum allowable connections was exceeded. However, if 2000 is the only called number in the modem pool, then there is no need to configure the max-conn option. The maximum connections allowed for the called number automatically default to the maximum number of modems in the pool. Additionally, the same called party number cannot be configured in multiple modem pools. Each called number must be assigned only to one modem pool.
router(config-modem-pool)#pool-range 30-50router(config-modem-pool)#called-number 2000 max-conn 21router(config-modem-pool)#exitrouter(config)#
The following configuration rejects the pool-range 30 command. Modem TTY line 30 is already a member of the modem pool accounts1, which was configured in the previous example.
router(config)#modem-pool accounts2router(config-modem-pool)#pool-range 30% TTY 30 is already in another pool.

To assign a range of modems to a modem pool, use the pool-range modem-pool configuration command.
pool-range number-number| number-number | Specifies a range of modems to be included as members in a modem pool. A dash (-) is required between the two modem numbers. The range of modems is equivalent to the number of modems in your access server that are not currently associated with another modem pool. |
Disabled. All modems are configured to be part of the system default modem pool.
Modem pool configuration
This command first appeared in Cisco IOS Release 11.2 P.
For a general description of modem pools and how they are configured on Cisco access servers, see the command reference page for the modem-pool command.
Replace the number-number argument with the modem TTY line numbers that correspond with the range of modems you want in the modem pool. TTY line numbers start from 1, which map to modem numbers that start from 0. For example, if you want modems 1/0 through 1/23 in a pool range, its TTY line numbers would be 1 to 24. To determine the exact modem number to TTY line mapping scheme for your access sever, issue the show modem slot/port command or show line command.
The following example assigns modem TTY lines 30 to 50 to the modem pool called accounts1. The modem pool's called number is set to 2000. The customers dialing 2000 are guaranteed access to 21 modems. The 22nd client to dial in will be refused connectivity because the maximum allowable connections was exceeded.

Modems cannot be assigned to more than one modem pool. The following example rejects the pool-range 30 command, because modem TTY line 30 is already a member in another modem pool.

To display the local disconnect reasons for all modems inside the system, use the show modem call-stats EXEC command.
show modem call-stats [slot]| slot | (Optional) Specifies the slot number, which limits the display output to a particular range of modems in the system. |
User and Privileged EXEC
This command first appeared in Cisco IOS Release 11.2 P.
Use this command to find out why an integrated modem in the access server ended its connection or why it is not operating at peak performance.
Local disconnect reasons for a particular modem are listed across the top of the screen display. For example, see lostCarr, dtrDrop, rmtLink, wdogTimr, compress, retrain, inacTout, and linkFail in the following output:
router# show modem call-stats
dial-in/dial-out call statistics
lostCarr dtrDrop rmtLink wdogTimr compress retrain inacTout linkFail
In the body of the screen display, the number of times an error occured on a specific modem is displayed (see the # column in the next example). The % column shows the total running percent that a modem was logged for the specified disconnect reason with respect to the entire group of modems. For example, out of all the times the lostCarr error occurred on all the modems in the system, the lostCarr error occurred 2% of the time on modem 0/0.
router# show modem call-stats
dial-in/dial-out call statistics
lostCarr dtrDrop rmtLink wdogTimr compress retrain inacTout linkFail

* 0/1 5 2 2 3 2 1 0 0 0 0 0 0 0 0 0 0
Bad or malfunctioning modems are detected by an unusually high number of disconnect counters for a particular disconnect reason. For example, if modem 1/0 had an astronomically high number of compression errors compared to the remaining modems in system, modem 1/0 would probably be bad or inoperable.
To reset the counters displayed by the show modem call-stats command, issue the clear modem counters command.
The following example shows call statistics for the show modem call-stats command. Due to the screen size limitation of most terminal screen displays, all the possible disconnect reasons cannot be displayed at the same time. Only the top eight most frequently experienced disconnect reasons are displayed.
See Table 4 for descriptions of the fields and end-connection events in the following sample display, which applies to MICA and Microcom modems.

Table 4 represents a combination of all the local disconnect reasons for MICA and Microcom modems; therefore, each type of modem will not generate all the following disconnect conditions.
| Field | Description |
|---|---|
| dial-in/dial-out call statistics | This category of disconnect reasons can happen only in dial-in or dial-out scenarios. |
|
Watchdog timeout. An obscure firmware problem occurred. This is a rare disconnect reason that occurs only on Microcom modems. |
|
Compression. An error was detected during decompression, which caused the internal decompression dictionary to overflow. This could be caused by a modem dialing in that is using a slightly different compression algorithm. This disconnect reason applies to MICA and Microcom modems. |
|
Retrain failure. A connection was lost and not re-established after three attempts. This disconnect reason applies to MICA and Microcom modems. For MICA modems only, too many consecutive retrains or speed shifts occurred. |
|
Inactivity timeout. The time specified in the AT/T command has expired. No modem data transfers were detected during that period. This disconnect reason applies to MICA and Microcom modems. For MICA modems only, received LD, but the partner's inactivity timer expired. Inactivity timeout occurred. LD inactivity was sent. |
|
Link failure. The protocol level link failed while using MNP-10 or LAPM in reliable mode. This disconnect reason applies only to Microcom modems. |
|
Modulation error. An error was detected at the DSP chip level, which caused a disconnect. This disconnect reason applies only to Microcom modems. |
|
MNP10 protocol error. An uncorrectable error occurred during a MNP-10 connection. This disconnect reason applies to MICA and Microcom modems. The following causes pertain only to MICA modems. Modem did not receive a LR frame during negotiation. The received LR frame is incompatible with local settings (second speaker). Too many consecutive retransmissions occurred. A protocol catch-all error occurred. A XID frame was not received during negotiation. The received XID is incompatible with the local settings (second speaker). Received a DM. Received a bad sequence number/ACK#. Received a SABME frame in steady state. Received XID in steady state. Received LR in steady state. Received unknown command code. Received FRMR with reason xx (bit mapped). Received FRMR bad command. Received FRMR data field or incorrect length (U frames). Received FRMR bad N(R). Received LD, but partner never received our LR. Received LD, but the LR has bad parameter #1. Received LD, but the LR was incompatible with partner's configuration. Received LD, but a MNP protocol error occurred. |
|
LAPM protocol error. An uncorrectable error occurred during a LAPM connection. This disconnect reason applies to MICA and Microcom modems. The following causes pertain only to MICA modems. Modem did not receive a LR frame during negotiation. The received LR frame is incompatible with local settings (second speaker). Too many consecutive retransmissions occurred. A protocol catch-all error occurred. A XID frame was not received during negotiation. The received XID is incompatible with the local settings (second speaker). Received a DM. Received a bad sequence number/ACK#. Received a SABME frame in steady state. Received XID in steady state. Received LR in steady state. Received unknown command code. Received FRMR with reason xx (bit mapped). Received FRMR bad command. Received FRMR data field or incorrect length (U frames). Received FRMR bad N(R). Received LD, but partner never received our LR. Received LD, but the LR has bad parameter #1. Received LD, but the LR was incompatible with partner's configuration. Received LD, but a MNP protocol error occurred. |
|
Lost carrier. The modem firmware detected a carrier drop during a connection. The cause for the carrier drop could be the loss of signal from the remote modem or the result of a error detection. This disconnect reason applies to MICA and Microcom modems. For MICA modems only, carrier lost (DSP). |
|
DTR drop. The modem disconnected because the DTR signal from the host became inactive. This disconnect reason applies to MICA and Microcom modems. For MICA modems only, a virtual DTR dropped. This status is reflected from the I/O port redirector, which is currently using the modem. |
|
User hang up. The modem disconnected because a command such as ATH was detected. This disconnect reason applies to MICA and Microcom modems. |
|
Remote link disconnect. If an MNP-10 reliable link is established, the remote modem sends the disconnect reason across the link before disconnecting. The disconnect reason displayed is LOCAL (remote link disconnect) and REMOTE (the reason the remote modem disconnected). This disconnect reason applies to MICA and Microcom modems. For MICA modems only, received a DISC frame with normal LAPM termination. |
|
Terminate. A password security error occurred in the Microcom HDMS. This error occurs only with Microcom modems. This disconnect reason applies only to Microcom modems. |
|
Callback failed. This error applies to leased line connections only. A switched line connection failed and a connection still cannot be made on the leased line. This disconnect reason applies only to Microcom modems. |
|
A failure was detected while the modem was training up. This disconnect reason applies only to MICA modems. |
|
A host issued a software_reset command. No host reason is available. The dialed number did not answer. The ATH command was detected by the host. This disconnect reason applies only to MICA modems. |
|
No EC fallback protocol was available. This disconnect reason applies only to MICA modems. |
|
Received LD, but the partner saw too many consecutive retransmissions. This disconnect reason applies only to MICA modems. |
| dial-out call statistics | This category of disconnect reasons can happen only in a dial-out scenario. |
|
No carrier. The called number answered, but no answer tone was detected after the appropriate wait. This disconnect reason applies to MICA and Microcom modems. For MICA modems only, no answer back tone was detected. A problem detecting end of answer back tone may have also occurred. A failure was detected while the modem was training up. Carrier lost (DSP). The connection took too long to complete. |
|
No dialtone. No dial tone was detected after the modem went off hook. This disconnect reason applies to MICA and Microcom modems. For MICA modems only, the host could not access the network. |
|
A busy signal was detected while the local modem was attempting to dial. This disconnect reason applies to MICA and Microcom modems. |
|
A character was received from the remote host after the dial command was issued and before a connection was established. This disconnect reason applies to MICA and Microcom modems. For MICA modems only, an AT mode "any key" abort occurred. |
|
Dialstring error. An invalid character was detected in the dial string, which forced the dial attempt to terminate. This disconnect reason applies only to Microcom modems. |
|
Auto logon error. An auto logon sequence did not successfully complete. This disconnect reason applies only to Microcom modems. |
|
Dial timeout. When a semicolon is used as a dial modifier, the modem returns to the command state as indicated by an "OK." This allows a continuation of the dial string. If a period of time elapses as specified in the S7 register without the dial string completing, the attempt is aborted with dial timeout as the disconnect reason. This disconnect reason applies only to Microcom modems. |
|
Remote hangup. The modem disconnected because the remote modem disconnected the call and dropped DTR. For MICA modems only, the ATH command was detected by the modem. |
|
Blacklist. In a country that supports blacklisting, an attempt was made to go off hook with a null dial string (ATD). This disconnect reason applies only to Microcom modems. |
|
CCP not seen. The credit card prompt (also known as Bong) was not detected. This disconnect reason applies only to Microcom modems. |
|
FAX class 2 error. An abnormal termination to a fax transmission was detected. This disconnect reason applies only to Microcom modems. |
|
Total number of times the disconnect reason occurred among all the modems in the system. |
To display connection speed statistics for all the modems running in the system, use the show modem connect-speeds EXEC command.
show modem connect-speeds [max-speed [slot]]| max-speed | (Optional) Maximum speed you want displayed in the shifting speed window. You can specify from 12,000 to 56,000 bps. |
| slot | (Optional) Specifies the slot number, which limits the display output to a particular range of modems in the system. |
The maximum speed displayed is 12,000 bps.
User and Privileged EXEC
This command first appeared in Cisco IOS Release 11.2 P.
Because most terminal screens are not wide enough to display the entire range of connection speeds at one time (for example, 75 to 56000 bps), the max-speed variable is used. This variable specifies the contents of a shifting baud-rate window, which provides you with a snap shot of modem connection speeds for your system. If you want to see a snap shot of lower baud rates, specify a lower connection speed. If you want to see a snap shot of higher baud rates, specify a higher connection speed.
The max-speed variable also rounds up to the nearest recognizable baud rate by the software, so you do no need to memorize or enter exact connection speeds. For example, if you enter a maximum baud rate of 22059, the system software automatically rounds the value up to 24000.
To display a complete picture of all the connection speeds and counters on the system, you must enter a series of commands. Each time you issue the show modem connect-speeds max-speed command, only nine baud rate columns can be displayed at the same time. Table 5 shows a range of commands that you can issue, one at a time, to see a complete picture of the total possible connection speeds on your access server.
| Command | Connect Speed Range Displayed |
|---|---|
| show modem connect-speeds 56000 | 40,000 to 56,000 bps |
| show modem connect-speeds 38000 | 24,000 to 38,000 bps |
| show modem connect-speeds 21600 | 2,400 to 21,600 bps |
| show modem connect-speeds 12000 | 75 to 1200 bps |
The show modem connect-speeds command displays a log of connection speed statistics starting from the last time the access servers or router was power cycled or the clear modem counters command was issued. If you want to create a monthly report of the connection speeds achieved by the modems, issue the clear modem counters command at the beginning of the month and issue the show modem connect-speeds command at the end of the month.
See Table 6 for descriptions of the fields shown in the following displays.
The following display shows connection speed statistics up to 28000 bps:

To display a snap shot of all the firmware versions running on all the modems in the access server, use the show modem mapping EXEC command. This command also shows the source location of each version of firmware (for example, running out of Flash, boot Flash, or bundled with Cisco IOS software).
This command first appeared in Cisco IOS Release 11.3 T.
This command is useful for managing and monitoring multiple versions of modem firmware running in an access server.
Modem firmware can reside in the access server's Flash, boot Flash, or bundled with the Cisco IOS software. To copy modem firmware that is bundled with Cisco IOS software to a modem or range of modems, issue the copy ios-bundled modem command
Firmware can also be copied from a local TFTP server to the onboard modems. For the Cisco AS5300, issue the copy tftp flash command followed by the copy flash modem command. The Cisco AS5300 stores individual firmware files that are not bundled with the Cisco IOS software in Flash memory. For the Cisco AS5200, issue the copy tftp bootflash command followed by the copy bootflash modem command. The Cisco AS5200 stores individual firmware files not bundled with the Cisco IOS software in boot Flash memory.
All the modems in a single MICA modem module run the same version of firmware (for example, modems 1/0 through 1/5 in module 0). However, different versions of modem firmware can exist between different modem modules (for example, module 0 and module 1).
Individual firmware files cannot be erased from Flash or boot Flash memory. The entire contents of Flash or boot Flash must be deleted during the erase operation. If you do this, be sure to backup your Cisco IOS software and running configuration before you erase your system's Flash or boot Flash.
The following is sample display output for the show modem mapping EXEC command. This access server is loaded with MICA and Microcom modems.

Each MICA modem has its own data channel port, which is tied to a TTY line. For example, modem 0/1 is tied to TTY line 2. To display data channel information for a single MICA modem, issue the show modem mica slot/port command.
All the modems on each MICA modem module share three pseudo channels for modem management functions, for example the DC session channel, status polling channel, and controlling channel. To view statistics for each modem management channel, issue the show modem mica all command. The first channel you see displayed is the status polling channel (shown as SLOT/PORT (0/61) TTYNUM=-1 (MM Status Port)). The second displayed channel is the DC session channel (shown as SLOT/PORT (0/60) TTYNUM=-1 (MM DC Port)). The third displayed port is the controlling channel (shown as SLOT/PORT (0/62) TTYNUM=-1 (Control Port)). No TTY lines are associated with the modem management ports, as indicated by the field display TTYNUM=-1. Finally, an extensive list of all the data channels for each MICA modem is displayed.
The following example displays the data port channel for modem 0/1. For a description of the significant fields in this display, see Table 11.

User EXEC
This general first appeared in Cisco IOS Release 11.2 P.
For a complete description of modem pools and how they are configured on Cisco access servers, see the command reference page for the modem-pool command.
The following example displays sample output for the show modem-pool command. Three modem pools are setup: System-def-Mpol, accounts1, and accounts2. Each modem pool contains two called party numbers. Fifty modems are assigned to each modem pool. Each called party number has a maximum of 25 connections. There are 20 modems in the system default pool, which is the pool that includes all the modems that were not assigned to a particular modem pool (for example, accounts1 or accounts2).

Table 13 describes the display fields in the previous example:
| Field | Description |
|---|---|
| modem-pool: | Name of the specified modem pool. In the previous example, there are three modem pools configured: System-def-Mpool, accounts1, and accounts2. To create or specify a modem pool, see the modem-pool command.
All modems that you did not intentionally assign to a modem pool (for example, accounts1) are automatically assigned to the system default pool (displayed as System-def-Mpool). |
| modems in pool: | Number of modems that are a member of the specified modem pool. In this example, 20 modems are in System-def-Mpool, 50 modems are in accounts1, and 50 modems are in accounts2. To setup this option, see the pool-range command. |
| modem-pool: active conn: | Number of simultaneous active connections for the specified pool. |
| no free modems in pool | Number of times incoming calls were rejected because there were no more free modems in the pool to accept the call. |
| test num of modems: | Number of modems tested in the modem pool. |
| called_party_number: | Specified called party number. This is the number that the remote clients are using to dial into the access server or router. You can have more than one call party number per modem pool. |
| called_party_number: active conn: | Number of simultaneous active connections for the specified called party number. |
| max conn allowed: | Maximum number of modems that a called party number can occupy at any given time. For example, if you create one modem pool to serve two or more services, this option sets limits on how many maximum connections each customer can have in to the modem pool. In this way, one service cannot occupy or monopolize an entire modem pool. Essentially, this feature provides overflow protection and sets dial-in limits. To configure this option, see the called-number command. |
| max-conn exceeded | Number of times an incoming call using this called party number was rejected because the max-conn number parameter specified by the called-number command was exceeded. |

To configure the speed for a Fast Ethernet interface, use the speed interface configuration command. Use the no form of this command to disable a speed setting.
speed {10 | 100 | auto}| 10 | Configures the interface to transmit at 10 Mbps. |
| 100 | Configures the interface to transmit at 100 Mbps. |
| auto | Turns on the Fast Ethernet auto-negotiation capability. The interface automatically operates at 10 or 100 Mbps depending on environmental factors, such as the type of media and transmission speeds for the peer routers, hubs, and switches used in the network configuration. |
100 Mbps
Interface configuration
This command first appeared in Cisco IOS Release 11.2 P.
The auto negotiation capability is enabled for the Fast Ethernet interface by issuing the speed auto interface configuration command or the duplex auto interface configuration command.
Table 14 describes the system's performance for different configuration combinations of the duplex command and the speed command. Reading across one row at a time, the specified duplex command configured with the specified speed command produces the resulting system action.
| Duplex Command | Speed Command | Resulting System Action |
|---|---|---|
| duplex auto | speed auto | Auto negotiates both speed and duplex modes. |
| duplex auto | speed 100 or speed 10 | Auto negotiates both speed and duplex modes. |
| duplex half or duplex full | speed auto | Auto negotiates both speed and duplex modes. |
| duplex half | speed 10 | Forces 10 Mbps and half duplex. |
| duplex full | speed 10 | Forces 10 Mbps and full duplex. |
| duplex half | speed 100 | Forces 100 Mbps and half duplex. |
| duplex full | speed 100 | Forces 100 Mbps and full duplex. |
The following example shows the configuration options for the speed command:
router#configure terminalEnter configuration commands, one per line. End with CNTL/Z. router(config)#interface fastethernet 0router(config-if)# speed ? 10 Force 10 Mbps operation 100 Force 100 Mbps operation auto Enable AUTO speed configuration
