This chapter describes the commands used to configure Integrated Services Digital Network (ISDN) calling, such as on-demand dialing and security.
This section describes the association between the ISDN directory numbers, the service profile identification numbers (SPIDs) and the analog telephone port(s) of the router.
SPIDS are in common use only in North America. If you are using ISDN Basic Rate Interface (BRI) service in North America, your telephone service provider might assign zero, one, or two SPIDs to your BRI line, depending on what kind of switch the service provider uses. For 5ESS Custom switches, no SPID is assigned if the service provider is using a point-to-point switch, and one SPID is usually assigned for a multipoint switch. For DMS-100, NI1 and NI1-compliant switches, two SPIDs are usually assigned. All other switch types usually do not use SPIDs.
If your BRI line is assigned two SPIDs, it is suggested that you use the first SPID directory number for data calls and the second SPID directory number for the incoming voice calls to reduce the chances a data call will be disconnected when the router receives incoming voice calls.
SPIDs define the services available to the router. SPID numbers are determined by your service provider. For example, a directory number is considered a service and is associated with a SPID. A SPID can have more than one directory number associated with it. Cisco 700 series routers support up to three directory numbers for each SPID and up to two SPIDs, for a total of six directory numbers.
The analog telephone ports are basic telephone service (POTS) ports, as opposed to an ISDN telephone port, such as the S/T port. The POTS ports are mapped to the directory numbers.
If no directory numbers are associated (mapped) to the POTS ports, the default function of analog telephones is dependent on the number of SPIDs assigned to the ISDN BRI line. Table 5-1 describes the default behavior of the POTS ports if your SPIDs and directory numbers are defined and you do not use the set phone command to configure the POTS ports.
| Analog Telephone Port Operation | No SPIDs or One SPID | Two SPIDs | SPIDs Not Used1 |
|---|---|---|---|
All incoming calls ring Phone 1. | X2 | X | X |
Phone 1 can call Phone 2. |
| X | X |
Two data calls are connected and voice priority is configured to always. If calls on the Phone 1 and Phone 2 ports are at the same time, only one data call is disconnected. |
| X | X |
This section applies only to North American analog telephone services.
The router recognizes the difference between a data call and a voice call. In some tariff areas, voice calls are less expensive than data calls. Cisco 700 series routers support incoming and outgoing DOV calls. DOV calls are data calls made over the BRI (voice) line using Voice Bearer Capability (VBC).
If a directory number has been configured for DOV, incoming data calls with VBC are routed to the LAN through the Ethernet port, as shown in Figure 5-1. Incoming voice calls are forwarded to the analog (voice) device over the analog telephone port, as shown in Figure 5-2.
The set dov command instructs the router to treat incoming calls to a specified directory number as data calls. (Before using the set phone command to configure DOV, you must set the directory number with the correct SPID, as described in the section "Configuring Directory Numbers," in this chapter.)
Any call received on the port that has been associated with this directory number is treated as DOV and is forwarded to the LAN. One or two directory numbers can be configured for DOV with the set phone command.
The set speed command with the voice keyword sets VBC on for outgoing DOV calls, enabling the features of VBC and DOV.
You can automatically disconnect a data call when a voice call is made or received and two data calls are in progress. The set voicepriority command determines if a data call will be disconnected when the router makes or receives a voice call.
If the priority is set to always, data calls are always bumped in favor of voice calls.
If the priority is set to conditional, the data call is disconnected from one channel if the data call can continue over another channel.
If the priority is set to never, data calls are never bumped in favor of voice calls.
If the priority is set to disable, data calls are handled as indicated by the set phone DOV command.
The voice priority mode is dependent on several factors, including the following:
Cisco 700 series routers have a Distinctive Ring Manager (DRM) that can support distinctive ringing cadences for up to six external devices using the set phone command. These external devices can be a telephone or fax machine. Each POTS interface can support up to three devices.
To make a manual ISDN call on a specified link to a specified telephone number, use the call command.
CAll [object] [number]
object | Can consist of a link or a channel. |
number | The telephone number of the remote ISDN device. If no telephone number is entered, the router calls the number configured in the current profile with the set number command. If no number is entered and the current profile has not been configured with a number, this command has no effect. |
None
System or profile mode
The object parameter can take one of these forms:
1. Connection
A logical data stream that connects the unit to the remote device. A connection can have multiple links associated with it. The syntax format for connection is as follows:
C#
2. Link
A logical 64/56-kbps data path assigned to users, numbered sequentially beginning with one. The unit is limited to two links. The two syntax formats for link are as follows:
L# or #
The # parameter can be either 1 or 2.
The three syntax formats for a connection and an associated link are as follows:
C#/L# or C#/# or #/#
3. Channel
Channels provide a physical data path over the WAN. Channels are one or more time slots kept in sequence through the WAN that do not require any kind of inverse multiplexing. The unit can support 64-kbps channels or (in INS release only) 128-kbps channels. The syntax format for a channel is as follows:
CH#
The # parameter can be 1 or 2.
If no link number is specified, the call is placed on both links. If no destination telephone number is specified, the unit uses the number configured for the current profile.
The following example makes a manual call on the second link to 408 555-1212 while in profile mode for profile 2503:
Host:2503> call 2 4085551212
set button
set number
To specify when an on-demand ISDN call will be made, use the demand command.
DEmand [link] [THreshold = kbps] [DUration= seconds] [SOurce =WAN | LAn | BOth]
link | Specifies the link with which all the following parameters are associated. |
THreshold | Minimum data rate (in kbps) that must exist on the channel before the call will be made. The range is 0 to 128.1 Inband negotiation traffic (traffic that terminates at the router) is not taken into account for the threshold level. |
DUration | Length of time (in seconds) that the traffic is to be above the data threshold before the call is made. The range is 1 to 255. |
SOurce | Source of traffic that is counted. |
WAN | Traffic received from the ISDN line. |
LAn | Traffic received from the LAN. |
BOth | The value of LAN or the ISDN traffic, whichever is higher. |
| 1The data rate measured is the data that the router intends to forward across the ISDN line, so the data rate might actually exceed the physical capacity of the line. |
Channel 1---threshold 0 duration 1 source lan
Channel 2---threshold 48 duration 1 source both
System or profile mode
On-demand dialing must be enabled with the set auto command.
The following example determines when on-demand dialing will take place for profile 2503:
Host:2503> demand 1 threshold 10 duration 2 source lan
This specifies that link 1 will dial if 10 kbps is continuously exceeded for 2 seconds.
set auto
set delay
set ppp callback
set ppp negotiation retry
set ppp negotiation count
set ppp bacp
set ringback
set timeout
timeout
show negotiation
To manually terminate an ISDN call, use the disconnect command.
DIsconnect [object | ALl]
object | ISDN B channel or link. Can be 1 or 2. If no channel or link is entered, any connected calls are terminated. |
ALl | Disconnects all calls. |
None
Profile mode
The object parameter can take one of these forms:
1. Connection
A logical data stream that connects the unit to the remote device. A connection can have multiple links associated with it. The syntax format for a connection is as follows:
C#
2. Link
A logical 64/56-kbps data path assigned to users, numbered sequentially beginning with one. The unit is limited to two links. The two syntax formats for link are as follows:
L# or #
The # parameter can be either 1 or 2.
The three syntax formats for a connection and an associated link are as follows:
C#/L# or C#/# or #/#
3. Channel
Channels provide a physical data path over the WAN. Channels are one or more time slots kept in sequence through the WAN that do not require any kind of inverse multiplexing. The unit can support 64-kbps channels or (in INS release only) 128-kbps channels. The syntax format for a channel is as follows:
CH#
The # parameter can be 1 or 2.
The router may automatically reconnect the call after using the disconnect command. This can occur if on-demand dialing is enabled and a telephone number has been entered with the set number command. If the router receives enough packets to meet the demand threshold parameters, a new call is made.
The following example disconnects a call on the first link:
Host> disconnect 1
The following example disconnects any calls on both links of the current connection:
Host> disconnect
set number
To reassign a released service profile identifier (SPID) to the router, use the establish command.
EStablish [spidid]
spidid | Specify the number of the SPID you are establishing (1 or 2) as set by the set spid command. |
None
System mode
This command is applicable only in the United States. It reassigns one of the SPIDs after it has been released to a device other than the router. For example, if you have two SPIDs and the router is using both of them for data, one of the SPIDs has to be released if an ISDN phone is to be used.
The following example reassigns the SPID ID2 to the router following a release:
establish 2
The following is a typical sequence of events:
1. A unit has two calls established.
2. A call is disconnected by the user to free the B channel.
3. User releases the second SPID by entering: REL 2. The message "Terminal Identifier Unassigned" displays.
4. The same SPID is activated by the user in another ISDN TE on the same DSL.
5. Use of the other TE is finished and the user frees the SPID.
6. User reactivates the SPID in the unit by entering: ES 2.
7. A second channel call is made by the user of the unit.
release
To release the Layer 2 link and Terminal Identifier (TEI) Unassigned associated with a SPID so that it can be used by another device on the same ISDN line (SBus), use the release command.
RElease [spidid]
spidid | Specify the number of the SPID you are releasing (1 or 2) as set by the set spid command. (North America only.) |
None
System mode
Use this command when your ISDN line only supports two SPIDs and one B channel per SPID (DMS-100). When released, the SPID still resides in memory, so you do not have to reenter the SPID. To reassign the SPID back to the router, use the establish command.
The following example releases the Channel 1 SPID from the router so that it can be used by another device on the same ISDN line:
Host> release 1
establish
To delete one or all of the directory numbers, use the reset directory number command.
REset DIrectorynumber ALl | number [.subaddress]
ALl | Deletes all the directory numbers entered with the set directory number or set phone command. |
number | Deletes the specified directory number that has been entered with the set directory number or set phone command. |
.subaddress | Subaddress of a device on a multipoint ISDN line. Can consist of 1 to 10 digits. |
None
System mode
If you reset all of the directory numbers, the RCAPI number is automatically reset.
To delete a directory number entered with the set directory number use one of the following commands:
Host> reset di all Host> reset di 14085559020
set directory number
set phone
set rcapi number
PHONE1 | PHONE2 | The directory number set (and ringing cadence) for each telephone interface will be disassociated. |
DOV | All of the DOV (Data Over Voice) directory numbers set are disassociated (a maximum of two). |
None
System mode
This command applies only to routers with analog telephone support.
To disassociate a directory number that has been entered with the set phone command:
Host> reset phone1
set phone
To extend the connection (after the idle time out has expired) based on the frequency of the Advise of Charge During Call (AOC-D), use the set aoctimeout command. The feature is also known as the fee pulse mode.
SEt AOctimeout ON [seconds] | OFfON | Enables the action time. |
seconds | The seconds required to terminate the logical connection. We recommend using the default value. This parameter has a range of 1 to 120 seconds. |
OFf | Disables the action time. |
4 seconds
Profile mode
The aoctimeout command can only be used in conjunction with the set timeout command. Before using this command, configure the set timeout command parameters, threshold kbps and duration seconds.
The following example enables the use of AOC-D supplemental service:
Host: set aoctimeout on
set timeout
To set voice encoding, use the set alawvoice command.
SEt ALawvoice ON | OFf
ON | Voice encoding is set to A-law. |
OFf | Voice encoding is set to micro-law (µ-law or Mu-law). |
On
System mode
For the NET3 switch type, the set alawvoice command changes the voice encoding to micro-law for countries such as Taiwan. Most countries that use the NET3 switch type use A-law voice encoding. This command is needed for countries (such as Taiwan) that require micro-law.
The following example sets voice encoding to A-law:
Host> set alawvoice on
To enable or disable on-demand dialing, use the set auto command.
SEt [link] AUto ON | OFf
link | |
|---|---|
ON | Enables on-demand dialing. |
OFf | Disables on-demand dialing. |
channel 1---enabled (on)
channel 2---enabled (on)
Profile mode
The following example disables on-demand dialing for the second channel:
Host> set 2 auto off
demand
set ppp callback
set ppp negotiation retry
set ppp negotiation count
set ppp bacp
set ringback
set timeout
show negotiation
To enable or disable automatic service profile identifiers (SPID) detection, use the set autodetection command.
SEt AUTODetection ON | OFf
ON | Specifies a North American switch with auto detection enabled. You must enter the directory number, including the area code. |
OFf | Disables the auto detection feature. You must enter the SPID numbers and switch type. |
Off
System mode
The auto-SPID and auto-switch detection features simplify the use of ISDN terminal equipment because there are fewer parameters to enter. Before the feature is enabled, the user only enters the local directory numbers and area code. No SPID number or switch type is required. This reduces the possibility of mistakes made by the user or the carrier.
During the detection process, the control software tries to register SPIDs with the switch based on the local directory numbers and area code. After a successful registration, the control software stores the detected SPIDs and switch type in NVRAM, as if they were entered by the user.
If auto detection fails to register SPIDs with the ISDN switch, the system prompts the user with an error message. The user will be required to manually enter SPID number(s) and switch type.
The auto-detection feature only applies to North American ISDN switches, usually a 5ESS Custom, DMS-100 Custom, NI1, or NI2 switch. The auto-detection mechanism might not work with any other switch, such as Siemens switch.
The user can enter up to six directory numbers in software Release 4.0(1) and higher, three for each interface. Including the area code helps the auto detection software speed up the registration process.
The following limitations are inherit in SPID auto detection.
The following example disables on-demand dialing for the second channel:
Host> set 1 directorynumber 4085551234 Host> set 2 directorynumber 4085552345 Host> set autodetection on
set directory number
set spid
set switch
To set a backup number, use the set backupnumber command.
SEt [link] BackupNUmber = [subaddress]
link | Logical 64/56-kbps data path assigned to users, numbered sequentially beginning with one. The unit is limited to two links. |
|---|---|
BackupNUmber | 1 to 20-digit telephone number of a device. |
.subaddress | Subaddress of a device on a multipoint ISDN line. Can consist of 1 to 10 digits. |
Profile mode
Cisco 700 series routers can place a call to a backup telephone number when an outgoing call is made. The call might not be successful because the receiving side is busy or does not answer. Cisco 700 series routers support second number fail-over for manual and auto data calls. Both the called number and the backup numbers must be configured.
The following example sets up a backup number:
Host> set backupnumber 18885551212
set number
To make and disconnect data calls, use the set button command.
SEt BUtton STandard | username | OFf
STandard | Used if no selection was made (the Standard profile telephone number is used). If you make more than one choice, the last one will be effective. |
OFf | Disables the button. |
System mode
This command applies only to Cisco 770 series routers and associates a profile with the ISDN make and break button. To use this command, choose an existing profile. The status of the button is displayed in the output of the show configuration command issued in system mode.
Table 5-2 summarizes the B-channel connection status and the button operation.
| Current Status | Button Operation |
|---|---|
No calls up | Make a data call |
1 Data call only | Disconnect data call |
2 Data calls | Disconnect both data calls |
1 Voice call only | Make a data call |
2 Voice calls | No action |
1 Data call and 1 Voice call | Disconnect data call |
The following example sets the button to use the Standard profile:
Host> set button standard
call
To disable or enable the call waiting, use the set callwaiting command.
SEt CALLWaiting [INterface=PHONE1 | PHONE2] ON | OFf
PHONE1 | PHONE2 | Sets call waiting for each specified telephone interface. |
ON | Enables call waiting. |
OFf | Disables call waiting. |
Enabled
System mode
This command applies only to routers with analog telephone support. If a fax machine or modem is connected to the analog telephone interface PHONE2, disable call waiting for PHONE2.
The following example disables the call waiting interface on PHONE2:
Host> set callwaiting IN=PHONE2 OFF
To change the call conference feature access code, use the set conference command.
SEt CONference = accesscode
accesscode | Call used by the service provider to activate the call conference feature. |
60
System mode
This command applies to NI1 and DMS switches only. Feature access codes for a particular supplementary service varies from ISP to ISP. There is no range for these codes.
The following example changes the code used by the service provider to activate the call:
Host> set conference = 66
groupnumber | Set a ring cadence for the analog telephone equipment for a specific country. |
1 (North America)
System mode
This command only applies to routers with analog telephone support. Ring cadences for the analog telephone equipment differ for each country. This command allows you to choose the appropriate ring cadence.
Table 5-3 lists each country group, associated group number, and the associated ring cadences.
| Country Group | Group Number | Ring Cadence |
|---|---|---|
USA, Canada | 1 | 2 41 |
Australia, Ireland, Singapore, United Kingdom, Malaysia | 2 | 0.4 0.2 0.4 2 |
Austria, Portugal, Sweden | 3 | 1 5 |
Belgium | 4 | 1 3 |
Denmark, Finland, Germany, Greece, Italy, Luxembourg, Mexico, Netherlands, Norway, Switzerland | 5 | 1 4 |
Finland, Sweden | 6 | 1 9 |
France | 7 | 1.5 3.5 |
Hong Kong | 8 | 0.4 0.2 0,4 3 |
Japan, Korea | 9 | 1 2 |
Spain | 10 | 1.5 3 |
| 1Underlined value indicates the ring duration in seconds. The numbers that are not underlined indicate a silence. |
The following example sets the current country group value to 1. The appropriate ring cadence takes effect immediately:
Host> set countrygroup 1
To set the time between unsuccessful demand call attempts, use the set delay command.
SEt [link] DElay seconds
link | Link to which the delay time applies. If no link is entered, the delay time is set for both links. |
DElay | Number of seconds between unsuccessful call attempts. This value can be between 10 and 32767 seconds. Another call is attempted when the delay time has expired only if the parameters set by the demand command are met. |
Link 1---30 seconds
Link 2---30 seconds
System mode
The delay time applies to all ISDN demand call attempts.
If the routers at both ends of an ISDN connection are configured with on-demand dialing enabled and the same delay time, unsuccessful calls can lead to a nonterminating error condition. This condition occurs when each router repeatedly tries to call the other at exactly the same delay time. Neither call will be successful, and both routers will repeat the call attempt at the same delay interval.
The following example sets the first channel to retry demand calls every 15 seconds:
Host> set 1 delay 15
demand
set backup number
To enter the router directory number, use the set directorynumber command.
SEt [spidid] DIrectorynumber = number [.subaddress]
spidid | The SPID ID can be 1 or 2. Depending on your ISDN service provider, your line might be assigned one or two SPIDs. If no SPID ID is specified, the directory number is associated with SPID1 in the case of switches with SPIDs. |
number | The directory number assigned by the telephone company. Can have 2 to 20 digits. For Cisco 760 and Cisco 770 series routers, a maximum of six directory numbers are allowed. For Cisco 750 series routers, a maximum of two directory numbers are allowed. |
.subaddress | Subaddress of a device on a multipoint ISDN line. Can have 1 to 10 digits. |
No directory number is configured.
System mode
To delete a directory number, use the reset directory number command.

766> set 1 di 5551234 766> set 2 di 5551235
If your BRI line is not assigned SPIDs, use the set directory number command without the spidid argument to configure the router with the directory numbers, for example:
766> set di 5551234
reset directory number
show voicerouting
To select the tone provided by the switch or the tone generated by the unit locally, use the set internaltones command.
SEt INTernaltones None | DIaltone | All
None | All tones are provided by the switch. |
DIaltone | Dialtone is generated locally. All the other tones are provided by the switch. |
All | All the tones are provided locally. |
None
System mode
This command applies only to European ISDN Net3 and 1TR6 switches.
Host> set internaltones none
To enable multidestination dialing, use the set multidestination command.
SEt MUltidestination ON | OFf
ON | Enables multidestination dialing. The router, through the use of profiles, is able to connect to multiple remote locations over ISDN. |
OFf |
Off (disabled)
System mode
When setting multidestination, make sure you are not creating a bridging loop.
The following example enables multidestination dialing:
Host> set multidestination on
To enter the ISDN telephone number that each link calls, use the set number command.
SEt [link] NUmber = [number .subaddress]
link | The link to which the telephone number is assigned. This number can be 1 or 2. If no link is specified, the number is applied to both links. |
|---|---|
number | The telephone number called when dialing on demand. The number can consist of 1 to 32 digits. This number should include all numbers required for the router to complete the call (for example, access codes and area codes). |
.subaddress | The subaddress of a device on a multipoint ISDN line. The address can be 1 to 10 digits. |
No ISDN telephone numbers configured.
Profile mode
To delete a number entered with the set number command, enter the command without the telephone number.
The following example sets a telephone number that is automatically dialed for profile 2503:
Host:2503> set 1 number 14085551234
The following example deletes the dialed number for profile 2503:
Host:2503> set 1 number
set auto
set plan
Use the set link permanent command to enable permanent connections.
SEt link PErmanent ON | OFf
link | Specifies channel 1, channel 2 or D, where the D channel has AO/DI configured. |
PErmanent | Specifies permanent mode of operation. |
ON | Enables permanent mode. |
OFf | Disables permanent mode. |
Off
Profile mode
Customers and Internet service providers (ISPs) in areas served by carriers providing flat-rate ISDN can have their lines connected permanently. This overrides any timeout and threshold parameters. It also allows the flexibility of having one or more channels permanently up.
This feature is not dependent on the switch for permanent connections and can work on any switch type.
On power up, the router tries to bring up all permanent connections. If for any reason a connection gets disconnected, the router attempts to reconnect.
If permanent mode is specified for more than one link on a single profile, all links come up only if Multilink PPP is configured. If the D channel is configured for permanent mode, it comes up only if no other B channels are active.
If the idling D channel configured for permanent mode is disconnected, it will not come up if any B channel is already connected, until the B channel call is discontinued. Permanent mode can be configured for three links only, two B channels and the D channel, across all profiles. If you enter this command after having configured it for two B channels and the D channel, an error message displays on the console screen.
The permanent mode setting overrides only timeout and threshold parameters and not other events such as
These events cause the line to be disconnected, but in permanent mode the router attempts to restore the line immediately.
show configuration
show demand
unset permanent
To select the interface to which the voice calls are routed, use the set phone command.
SEt PHONE1 | PHONE2 | DOV number [.subaddress][ring1 | ring2 | ring3]
PHONE1 PHONE2 | The telephone interface to which the voice calls will be routed. If no interface has been associated with an incoming voice call, the default routing will be to PHONE1. |
DOV | (Data Over Voice) If a directory number is associated with the DOV interface, all incoming voice calls to that number will be treated as data over voice calls and routed to the Ethernet interface. |
number | The directory number associated with that interface. There is one directory number per telephone interface. Two directory numbers can be assigned to be data over voice. |
.subaddress | Subaddress of a device on a multipoint ISDN line. This number can have 1 to 10 digits. |
ring1 | Specifies the ringing cadence. If the ringing cadence is not specified, the original country's tone is generated. Ring 1 signals DRM to route the incoming call to output port 1. |
ring2 | Specifies the ringing cadence. If the ringing cadence is not specified, the original country's tone is generated. Ring 2 signals DRM to route the incoming call to output port 2. |
ring3 | Specifies the ringing cadence. If the ringing cadence is not specified, the original country's tone is generated. Ring 3 signals DRM to route the incoming call to output port 3. |
PHONE1
System mode
If you are connected to a 5ESS Custom switch and you have assigned multiple directory numbers to a SPID, an incoming voice call destined for a secondary directory number is routed as the primary directory number. As a result, the call is routed to a different phone interface or uses a different ring cadence than expected.
The Distinctive Ringing feature provides up to three distinctive ring cadences that can be assigned to directory numbers.
Ring Type 1 | 2 seconds on, 4 seconds off |
|---|---|
Ring Type 2 | 0.8 seconds on, 0.4 seconds off, 0.8 seconds on, 4 seconds off |
Ring Type 3 | 0.4 seconds on, 0.2 seconds off, 0.4 seconds on, 0.2 seconds off, 0.8 seconds on, 4 seconds off |
The following example sets the telephone interface, directory number, and ring cadence:
Host> set phone1 6592651 ring1
reset phone
To set the numbering plan for outgoing calls, use the set plan command.
SEt PLan NOrmal | INternational | NAtional | SUbscriber | UNknown ISDN | ABbreviated | CEntrex| NEtwork
NOrmal | Unknown numbering type with unknown numbering plan (most common case). |
INternational | The international numbering type with ISDN numbering plan. |
NAtional | The national umbering type with ISDN numbering plan. |
SUbscriber | Local numbering type with ISDN numbering plan. |
UNknown ISDN | Unknown numbering type with ISDN numbering plan. |
ABbreviated | Abbreviated numbering type with private numbering plan. |
CEntrex | |
NEtwork | Network specific numbering type with private numbering plan. |
Normal
Profile mode
The numbering plan is the type of telephone numbering plan the router uses when making calls. Numbering plans are predefined settings that configure calls so that they conform to telephone system requirements.
The following example sets the router to use the international numbering plan when making calls:
Host> set plan international
To set the router's ringback number, use the set ringback command.
SEt [link] RIngback [number [.subaddress]]
link | The ISDN B channel to which the ringback number applies. Can be 1 or 2. If no channel is specified, the ringback number applies to both channels. |
number | The number sent to the remote router to make a callback to the Cisco router (your local router phone number). Can be 1 to 32 digits. This number must include all the digits necessary for the remote router to complete a call to the Cisco router, for example, area and access codes. |
.subaddress | Specifies a particular device on a multipoint ISDN line. Can be 1 to 10 digits. |
No ringback number is configured.
Profile level
The ringback number is the number string used by the remote router to make a callback to your router. If a remote router is calling in from a different area code, requires a different access codes or a country code, it might be necessary to specify that ringback number in each profile. For example, the ringback number for a remote router in the same area code might be 555-1234 while the ringback number for a remote router outside the area code might be 1408555-1234, and the ringback number for a remote router on a PBX might be 95551234.
If BACP or BAP is used, the ringback number has another function; to make a second-channel call, the router uses a combination of the number it used to make the first-channel call, and the remote router's second-channel ringback number.
For example, the Cisco router calls 555-1234 to reach the first channel of the remote router. If the second channel telephone number is 555-5678, set the remote router's second-channel ringback number to 5678. The Cisco router uses the prefix of the first number it called (555) plus the second channel's ringback number (5678) to make the second call.
The following example sets the number that a remote router uses when making a callback to the Cisco router on the first ISDN B channel:
Host> set 1 ringback 14155551234
demand
set auto
set ppp callback
set ppp negotiation retry
set ppp negotiation count
set ppp bacp
set timeout

To set the speed of data calls, use the set speed command.
SEt SPeed 56 | 64 | AUto | VOice
56 | Outgoing calls are made and connected at 56 kbps. Incoming calls are connected at 56 kbps. |
|---|---|
64 | Outgoing calls are made and connected at 64 kbps. Incoming calls are connected at 64 kbps, unless Bearer Capability (BC) indicates the call is at 56 kbps. In this case, calls are connected at 56 kbps. |
AUto | Outgoing calls are attempted at 64 kbps. If unsuccessful, the call is retried. Incoming calls are connected at the speed indicated by BC and ISDN messages. |
VOice | Outgoing calls are made using Voice Bearer Capability (VBC) and data is transferred at 56 kbps. Used for Data Over Voice (DOV). This parameter is used only in the United States. Incoming calls are connected as in auto mode. |
Auto
Profile mode
The voice keyword should be used only with ISDN switch types 5ESS, DMS or NI1.
The following example sets the speed for data calls to 64 kbps for profile 2503:
Host:2503> set speed 64
To enter a service profile identifier (SPID), use the set spid command. (North America only.)
SEt [spidid] SPId [spidnumber]
spidid | (Optional if there is only one SPID) Used as a convenient single-digit number to identify the actual long SPIDs allocated by service providers. |
spidnumber | Number identifying the service to which you have subscribed. This value is assigned by the ISDN service provider and is usually a ten-digit telephone number with some extra digits. The SPID number can consist of 1 to 20 digits. |
No SPIDs are configured.
System mode
To delete a previously entered SPID, use the set spid command without the SPID number argument.
The following example sets two SPIDs for the line:
Host> set 1 spid 0408555123401 Host> set 2 spid 0405555123402
The following example deletes the first SPID:
Host> set 1 spid

PERM64 | Dedicated line service that enables the unit to use a single 64-kbps data stream connected to one port. With this option, Channel 1 runs at 64 kbps, and Channel 2 is not used. NTT's Super Digital service is an example of a leased line server. (Japan) |
PERM128 | Dedicated line service that enables the unit to use a single 128-kbps data stream connected to one port. With this option, Channel 1 and 2 are combine to run at 128 kbps. (An example is Japan NTT's HSD service.) |
PERM2X64 | Bundles the B channels even if they are not synchronized. (When the unit is set in PERM128 mode, only one PPP session runs at 128 kbps, and both B channels must be synchronized.) |
The switch type depends on which image of the Cisco IOS-700 software is loaded. For example, if your image is c760-in.b-US.41-1, the default is 5ESS.
System mode
Not all switch settings are available to all users. The switch type available depends on the type of software loaded into the unit.
perm2x64 enables the router to use both of the 64-kbps data streams for connecting to the remote end. In this mode, the B channels are bundled together to total 128 kbps, with the help of Multilink PPP (MLP).
When the unit is set in PERM128 mode, only one PPP session runs at 128 kbps and both B channels must be synchronized. PERM2X64 mode bundles the B channels even if they are not synchronized.
The following example configures the ISDN switch type as DMS:
Host> set switch dms
To configure the amount of time the ISDN line remains idle before disconnecting, use the set timeout command. This command sets the same parameter as the timeout duration command.
SEt [link] TIMEout [seconds | OFf]
link | The ISDN link to which the timeout parameters apply. |
seconds | Time (in seconds) that the ISDN line will remain idle before disconnecting. Can be between 1 and 32767 seconds. |
OFf | The ISDN line will not disconnect automatically. |
Off
Profile mode
The following example configures both ISDN B channels to disconnect after 5 minutes for profile 2503:
Host:2503> set 1 timeout 300 Host:2503> set 2 timeout 300
demand
set aoctimeout

To change the call conference feature access code, use the set transfer command.
SEt TRansfer = accesscode
accesscode | Call used by the service provider to activate the call transfer feature. |
9
System mode
This command applies to NI1 and DMS switches only.
The following example changes the code used by the service provider to activate the call:
Host> set transfer = 67
INcoming | Priorities are being set for incoming calls. |
OUtgoing | Priorities are being set for outgoing calls. |
INterface | Takes the values of PHONE1 or PHONE2. When neither is specified, it will apply to both PHONE1 and PHONE2. |
ALways | Sets voicepriority to be active under all circumstances. Data calls are always bumped for voice calls. |
COnditional | Sets voicepriority to disconnect data calls only if the network connection can be guaranteed (that is only if there are two data calls to the same destination). |
NEver | Disables voicepriority; data calls are never bumped for voice calls. |
Always
System mode
Voice priority can be set in a variety of ways. Table 5-4 lists the settings and the modes for inbound calls.
| Inbound Calls | |||
|---|---|---|---|
Mode | 2 data channels destination A | 1 data channel to destination A, 1 data channel to destination B | 1 data channel to destination A, but the offered channel is the one in use |
Always | Bump 1 data channel when inbound call is answered by going off-hook | Bump 1 data channel when inbound call is answered by going off-hook | Bump data call when inbound is answered |
Conditional | Bump 1 data channel when inbound call is answered by going off-hook | No bump; ring busy | No bump; ring busy |
Never | No bump; ring busy | No bump; ring busy | No bump; ring busy |
Table 5-4 lists the settings and the modes for outbound calls.
| Outbound Calls | |||
|---|---|---|---|
Mode | 2 data calls to destination A | 1 data call to destination A and 1 data call to destination B | 1 data call to destination A, but the telephone's channel is the one in use |
Always | Bump 1 data call when the telephone goes off-hook | Bump 1 data call when the telephone goes off-hook | Bump the existing dataphone when the call goes off-hook |
Conditional | Bump 1 data call when the telephone goes off-hook | No bump; ring busy | No bump; ring busy |
Never | No bump; ring busy | No bump; ring busy | No bump; ring busy |
The following example configures voice priority for incoming calls on both telephone interfaces to conditional mode:
Host>set voicepriority conditional
To display the current status of the ISDN line and both B channels, use the show status command.
SHow STatusSystem or profile mode
The following example shows output from the show status command:
