Basic Configuration

This chapter describes how to use the Cisco IOS software command-line interface (CLI) to configure basic access server functionality, including:

Follow the procedures in this chapter to configure the access server manually or if you want to change the configuration after you have run the setup script (described in "First-Time Configuration."

This chapter does not describe every configuration possible--only the most commonly used configuration procedures. For advanced configuration topics and procedures, go to "Advanced Configuration."

You can also view these publications on the Documentation CD-ROM that arrived with your access server, or you can order printed copies separately.

If you are experienced using the Cisco IOS software, you might find the "Where to Go Next" section at the end of this chapter a useful reference for configuration.

Note   If you skipped ""Using Cisco IOS Software," and you have never configured a Cisco access server, return to this chapter and read it now.

Configuring the Host Name and Password

One of the first configuration tasks you might want to do is configure the host name and set an encrypted password. Configuring a host name allows you to distinguish multiple Cisco access servers from each other. Setting an encrypted password allows you to prevent unauthorized configuration changes.

Configure

	Command	Purpose
Step1	5400>enable Password: password 5400#	Enter enable mode (also called privileged EXEC mode) and enter the password. You have entered enable mode when the prompt changes to 5400#.
Step2	5400#configure terminal Enter configuration commands, one per line. End with CNTL/Z. 5400(config)#	Enter global configuration mode. You have entered global configuration mode when the prompt changes to Router(config)#.
Step3	Router(config)# hostname 5400 5400(config)#	Change the name of the access server to a meaningful name. Substitute your host name for 5400.
Step4	5400(config)# enable secret guessme	Enter an enable secret password. This password provides access to privileged EXEC mode. When a user types enable at the EXEC prompt (5400> ), they must enter the enable secret password to gain access to configuration mode. Substitute your enable secret for guessme.
Step5	5400(config)# line con 0 5400(config-line)# exec-timeout 0 0 5400(config-line)# exit 5400(config)#	Enter line configuration mode to configure the console port. When you enter line configuration mode, the prompt changes to 5400(config-line)#. Prevent the access server's EXEC facility from timing out if you do not type any information on the console screen for an extended period. Exit back to global configuration mode.

Verify

To verify that you configured the right host name and passwords:

• Enter the show config command:

5400(config)# show config
Using 1888 out of 512000 bytes
!
version XX.X
.
.
!
hostname 5400
!
enable secret 5 $1$60L4$X2JYOwoDc0.kqa1loO/w8/
.
 

Check the host name and encrypted password displayed near the top of the command output.

• Exit global configuration mode and attempt to reenter it using the new enable password:

5400# exit
 
5400 con0 is now available 
Press RETURN to get started. 
5400> enable 
Password: guessme 
5400# 

---

Tips If you are having trouble:

---

• Make sure you entered the correct passwords.

• Passwords are case sensitive.

---

Configuring Alarms

Facility alarms currently monitor the following failure events:

5400# no facility-alarm detect rps

Configure

	Command	Purpose
Step1	5400>enable Password: password 5400#	Enter enable mode (also called privileged EXEC mode) and enter the password. You have entered enable mode when the prompt changes to 5400#.
Step2	5400#configure terminal Enter configuration commands, one per line. End with CNTL/Z. 5400(config)#	Enter global configuration mode. You have entered global configuration mode when the prompt changes to 5400(config)#.
Step3	5400(config)#facility-alarm detect interface [interface type] [slot/port]	Turn on alarm when interface goes down. Enter interface type and slot/port designation.
Step4	5400(config)#facility-alarm detect controller [t1 | e1 | t3] [slot/port]	Turn on alarm when controller goes down. The slot values range from 1 to 7. The port values range from 0 to 7 for T1 and E1. For T3, the port value is always 0.
Step5	5400(config)#facility-alarm detect modem-board [slot]	Turn on alarm when modem board present in slot# fails.
Step6	5400(config)#facility-alarm detect rps	Turn on alarm when RPS failure event is detected, any of the following failures will turn on the alarm. I/P voltage failure O/P voltage failure Overvoltage condition Multiple failures
Step7	5400(config)# facility-alarm detect temperature	Turn on alarm if thermal failure event is detected.
Step8	5400(config)# facility-alarm detect fan	Turn on alarm if fan failure event is detected.
Step9	5400(config-if)#Ctrl-Z 5400#	Return to enable mode.

Verify

To see the status of the alarms, enter the show facility-alarm command:

5400# show facility-alarm
    Device            State
    ------            -----
 
  FastEthernet0/0      UP
  Modem Card 4         UP
 
 Facility Alarm is ON

---

Tips If you are having trouble:

---

• Make sure the cable connections are not loose or disconnected.

• Make sure you are using Number 12 or 14 AWG copper wires to connect to the alarm port terminal blocks.

• Make sure your alarm is operational.

---

Configuring FastEthernet

Assign an IP address to the FastEthernet interface of your access server so that it can be recognized as a device on the Ethernet LAN. The FastEthernet interface supports 10- and 100-Mbps speeds with the 100BaseT and 10BaseT routers, hubs, and switches.

Configure

	Command	Purpose
Step1	5400>enable Password: password 5400#	Enter enable mode (also called privileged EXEC mode) and enter the password. You have entered enable mode when the prompt changes to 5400#.
Step2	5400#configure terminal Enter configuration commands, one per line. End with CNTL/Z. 5400(config)#	Enter global configuration mode. You have entered global configuration mode when the prompt changes to 5400(config)#.
Step3	5400(config)#interface fastethernet 0/0 5400(config-if)#	Enter Ethernet interface configuration mode, where 0/0 is the slot/port designation.
Step4	5400(config-if)#ip address 172.16.254.250 255.255.255.0	Assign an IP address and subnet mask to the interface.
Step5	5400(config-if)#speed 100	Assigns speed 100 Mbps to FastEthernet. This is the default value. Note   See Table 3-1 for details on using different combinations of speed and duplex options.
Step6	5400(config-if)#duplex full	Sets FastEthernet to operate at full duplex. Note   To use the auto-negotiation capability (that is, detect speed and duplex modes automatically), you must set both speed and duplex to auto. Setting speed to auto negotiates speed only, and setting duplex to auto negotiates duplex only. Note   See Table 3-1 for details on using different combinations of duplex and speed.
Step7	5400(config-if)#no shutdown	Brings up the interface and enables a connection to the network.
Step8	5400(config-if)#Ctrl-Z 5400#	Return to enable mode.

Table 3-1: Using Different Duplex and Speed Options

Duplex Mode	Speed Mode	Action
auto	auto	Auto negotiates speed and duplex modes.
auto	100/10	Auto negotiates duplex mode.
half/full	auto	Auto negotiates speed mode.
half	10	Sets 10 Mbps for speed and half-duplex for duplex.
full	10	Sets 10 Mbps for speed and full-duplex for duplex.
half	100	Sets 100 Mbps for speed and half-duplex for duplex.
full	100	Sets 100 Mbps for speed and full-duplex for duplex.

Verify

To verify the IP address, configured speed and duplex mode operations:

• Enter the show arp command to verify the IP address:

5400# show arp

Configuring Synchronous Serial Interfaces for WAN Support

Configure the synchronous serial interfaces on the motherboard to connect to a WAN through a CSU/DSU.

This section describes how to enable the serial interface, specify IP routing, and set up external clock timing on a DCE or DTE interface. To use a port as a DTE interface, you need only connect a DTE adapter cable to the port. When the system detects the DTE mode cable, it automatically uses the external timing signal. To use a port in DCE mode, you must connect a DCE interface cable and set the clock speed with the clock rate configuration command. You must also set the clock rate to perform a loopback test.

Configure

	Command	Purpose
Step1	5400>enable Password: password 5400#	Enter enable mode (also called privileged EXEC mode) and enter the password. You have entered enable mode when the prompt changes to 5400#.
Step2	5400#configure terminal Enter configuration commands, one per line. End with CNTL/Z. 5400(config)#	Enter global configuration mode. You have entered global configuration mode when the prompt changes to 5400(config)#.
Step3	5400(config)# interface serial 0/0	Specify the first interface to be configured.
Step4	5400(config-int)# ip address 172.22.4.67 255.255.255.0	If IP routing is enabled, assign an IP address and subnet mask to the interface.
Step5	5400(config-int)# clock rate 2015232	Configure the external clock signal only if you are configuring a DCE interface. The available options include 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 56000, 64000, 128000, and 2015232.
Step6	5400(config-int)# no shutdown	Change the shutdown state to up and enable the interface.
Step7	5400(config-controller)#Ctrl-Z 5400#	Return to enable mode.

Verify

To verify you have configured the interfaces correctly:

• Specify one of the new serial interfaces with the show interfaces serial port command and verify that the first line of the display specifies the interface with the correct slot number. Also verify that the interface and line protocol are in the correct state: up or down.

• Display the entire system configuration file with the show configuration command. Verify that the configuration is accurate for the system and each interface.

Tips If you are having trouble, make sure the network interface is properly connected and terminated.

Configuring Channelized T1 and E1 Dial Feature Cards

On a Cisco AS5400, you can allocate the available channels for channelized E1 and T1 in the following ways:

• All channels can be configured to support ISDN PRI.

• If you are not running ISDN PRI, all channels can be configured to support robbed-bit signaling (also known as channel-associated signaling), which enables a Cisco AS5400 modem to receive and transmit analog calls.

• All channels can be configured in a single channel group.

• Mix and match channels supporting ISDN PRI and channel grouping.

• Mix and match channels supporting ISDN PRI, robbed-bit signaling, and channel grouping across the same T1 line. For example, on the same channelized T1 you can configure the pri-group timeslots 1-10 command, channel-group 11 timeslots 11-16 command, and cas-group 17 timeslots 17-23 type e&m-fgb command. This is a rare configuration because it requires you to align the correct range of timeslots on both ends of the connection.

Note   For configuration information about leased line or non-dial use, see section "Configuring Synchronous Serial Interfaces for WAN Support" and the Cisco IOS Configuration Fundamentals Configuration Guide publication available online.

Controller Numbering

The CT1/E1 controller numbering convention is dfc-slot/port in CLI commands. DFC slot numbering starts from the motherboard and works up from left to right. Slot 0 is reserved for the motherboard. The CT1/E1 DFC slots are numbered sequentially from 1 to 7. Port numbering is from 0 to 7.

Configure

	Command	Purpose
Step1	5400>enable Password: password 5400#	Enter enable mode (also called privileged EXEC mode) and enter the password. You have entered enable mode when the prompt changes to 5400#.
Step2	5400#configure terminal Enter configuration commands, one per line. End with CNTL/Z. 5400(config)#	Enter global configuration mode. You have entered global configuration mode when the prompt changes to 5400(config)#.
Step3	5400(config)#controller [t1 | e1] slot/port 5400(config-controller)#	Enter controller configuration mode to configure your controller slot and port. The slot values range from 1 to 7. The port values range from 0 to 7 for T1 and E1.
Step4	5400(config-controller)#framing esf	Enter your telco's framing type.
Step5	5400(config-controller)#linecode b8zs	Enter your telco's line code type.
Step6	5400(config-controller)#Ctrl-Z 5400#	Return to enable mode.

Verify

To verify your controller is up and running and no alarms have been reported:

• Enter the show controller command and specify the controller type, slot, and port numbers:

5400# show controller t1 1/7
T1 1/7 is up.
  No alarms detected.
  Framing is ESF, Line Code is AMI, Clock Source is Line Primary.

Note the following:

• The controller must report being up.

• No errors should be reported.

The TDM subsystem troubleshooting commands are not used during normal system operation. Instead, the Cisco IOS commands show the current status and settings of the TDM backplane, enable debug output for display to the user when TDM programming occurs, and provide a set of test commands to test the functionality of the TDM path. TDM commands are generally used only by a Cisco technical support representative during troubleshooting of data continuity problems.

---

Note   For details on the TDM feature, refer to the Cisco IOS software configuration guide and command reference publications. These publications are available on the Documentation CD-ROM that came with your access server, on the World Wide Web from Cisco's home page, or you can order printed copies.

---

---

Tips If you are having trouble:

---

• First decide if the problem is due to the T1 or E1 line or with a particular channel group. If the problem is with a single channel group, you have a potential interface problem. If the problem is with the T1 or E1 line, or with all channel groups, you have a potential controller problem. (See "Configuring CT1 Channel Groups" section).

• To troubleshoot your E1 or T1 controllers, first check that the configuration is correct. The framing type and line code should match to what the service provider has specified. Then check channel group and PRI-group configurations, especially to verify that the timeslots and speeds are what the service provider has specified. At this point, the show controller t1 or show controller e1 commands should be used to check for T1 or E1 errors. Use the command several times to determine if error counters are increasing, or if the line status is continually changing. If this is occurring, you need to work with the service provider.

Configuring Channelized T3 Dial Feature Card

Your AS54-DFC-CT3 card offers 28 individual T1 channels (bundled in the T3) for serial transmission of data. The CT3 link supports the maintenance data link channel in C-Bit parity mode and also payload and network loopbacks. The T1s multiplexed in the CT3 link supports facilities data link (FDL) in extended super frame (ESF) framing.

Additionally, you can allocate your CT1 channels in the manner that was described in the "Configuring Channelized T1 and E1 Dial Feature Cards" section .

Controller Numbering

The CT3 controller numbering convention is dfc-slot/port in CLI commands. DFC slot numbering starts from the motherboard and works up from left to right. Slot 0 is reserved for the motherboard. The DFC slots are numbered sequentially from 1 to 7. Port number value is always 0.

Under the CT3, the CT1 controller numbering convention is dfc-slot/port:channel in CLI commands. Port numbering values range from 1 to 28.

Configuring CT1 Channel Groups

You can configure up to 24 channel groups for each CT1 on your AS54-DFC-CT1 and AS54-DFC-CT3 cards for backup links or serial backhaul connections.

First, you must define the timeslots that belong with each channel group. Channel groups are numbered 0 to 23, and timeslots are numbered 1 to 24. Defining a channel group creates a serial interface; defining multiple channel groups creates an equal number of serial interfaces that you can configure independently.

The channel group numbers for each CT1 controller can be arbitrarily assigned.

Configure

Perform the following task in controller configuration mode to define the channel groups and timeslots:

	Command	Purpose
	5400(config-controller)# channel-group number timeslots range [speed {48 | 56 | 64}]	Define the channel group number and, if needed, circuitspeed.1 Note   Working with your local service provider, you can create channel-groups with from one to 24 timeslots. These timeslots can be in any order, contiguous or noncontiguous.

1In the United States, channel-group speeds can be either 56 kbps or 64 kbps; the default is 56 kbps. If 64 kbps is used, it is recommended to be used with framing type of ESF and a linecode of B8ZS. The speed you select must match the speed provided by the telephone company.

After you define the T1 channel groups, you can configure each channel group as a serial interface. In other words, you can think of each channel group as a virtual serial interface. Subinterface configuration is also supported on the created serial interface.

Perform the following task in global configuration mode to enter interface configuration mode and configure the serial interface that corresponds to a channel group:

	Command	Purpose
	5400(config)# interface serial slot/port:channel-group	Define the serial interface for a CT1 channel group.

Verify

The following example shows a channelized T1 controller configured for channel groups and an ISDN PRI group. The pri-group command and the channel-group command cannot have overlapping timeslots; note the correct timeslot configuration.

Configuring ISDN PRI

Your AS54-DFC-8CT1, AS54-DFC-8CE1 and AS54-DFC-CT3 cards support ISDN PRI. ISDN, which uses the D channel for signaling and the B channels for user data provides out-of-band signaling.

Channelized T1 ISDN PRI offers 23 B channels and 1 D channel. Channelized E1 ISDN PRI offers 30 B channels and 1 D channel. Channel 24 is the D channel for T1, and channel 16 is the D channel for E1.

For a complete description of the commands mentioned in this chapter, refer to the Dial Solutions Command Reference available online.

Request PRI Line and Switch Configuration from a Telco Service Provider

Before configuring ISDN PRI on your Cisco router, you need to order a correctly provisioned ISDN PRI line from your telecommunications service provider.

• Verify if the outgoing B channel calls are made in ascending or descending order. Cisco IOS default is descending order however, if the switch from the service providers is configured for outgoing calls made in ascending order, the router can be configured to match the switch configuration of the service provider.

• Ask for delivery of calling line identification. Providers sometimes call this CLI or automatic number identification (ANI).

• If the router will be attached to an ISDN bus (to which other ISDN devices might be attached), ask for point-to-multipoint service (sub addressing is required) and a voice-and-data line.

Table 3-2 provides a sample of the CT1 configuration attributes you might request for a PRI switch.

Table 3-2: CT1 Configuration Attributes

Attribute	Value
Line format	Extended Superframe Format (ESF)
Line coding	Binary 8-zero substitution (B8ZS)
Call type	23 incoming channels and 23 outgoing channels

Controller Numbering

The CT1/E1 controller numbering convention is dfc-slot/port in CLI commands. DFC slot numbering starts from the motherboard and works up from left to right. Slot 0 is reserved for the motherboard. The CT1/E1 DFC slots are numbered sequentially from 1 to 7. Port numbering is from 0 to 7.

The CT3 controller numbering convention is dfc-slot/port in CLI commands. DFC slot numbering starts from the motherboard and works up from left to right. Slot 0 is reserved for the motherboard. The DFC slots are numbered sequentially from 1 to 7. Port number value is always 0.

Under the CT3, the CT1 controller numbering convention is dfc-slot/port:channel in CLI commands. Port numbering values range from 1 to 28.

Note   Your Cisco AS5400 supports a total of 248 ISDN channels. If you are configuring individual T1 channels of your CT3 for backup links or serial backhaul connections, the CT1s must be configured into channel-groups--each channel-group using 24 timeslots or channels. For example, to configure 6 CT1s (6*24), 144 ISDN channels are in use leaving a remainder of 104 (248-144) channels for ISDN use. See "Configuring CT1 Channel Groups" section.

Tips If you are having trouble:

---

• Make sure the cable connection is not loose or disconnected if the Layer 1 Status is "Deactivated." This status message indicates a problem at the physical layer.

• There may be a problem with your telco or the framing and line code types you entered may not match your telco's. A Layer 2 error indicates that the access server cannot communicate with the telco. There is a problem at the data link layer.

Configuring ISDN NFAS on CT1 PRI Groups

ISDN Non-Facility Associated Signaling (NFAS) allows a single D channel to control multiple PRI interfaces. A backup D channel can also be configured for use when the primary NFAS D channel fails.

When configuring NFAS for channelized T1 controllers configured for ISDN, you use an extended version of the ISDN pri-group command to specify the following :

• The range of PRI timeslots to be under the control of the D channel (timeslot 24).

• The function to be performed by timeslot 24 (primary D channel, backup, or none); the latter specifies its use as a B channel.

• The group identifier number for the interface under this D channel's control.

Note   Your Cisco AS5400 must connect to a Primary-4ess, Primary-DMS 100 or Primary-NI switch (see Table 3-3). It must also have a channelized T1 controller and, as a result, be ISDN PRI capable.

Configure

To configure ISDN NFAS, complete the following tasks in controller configuration mode:

Command	Purpose
5400(config-controller)# pri-group timeslots 1-24 nfas_d primary nfas_interface number nfas_group number	On one channelized T1 controller, configure the NFAS primary D channel.
5400(config-controller)# pri-group timeslots 1-24 nfas_d backup nfas_interface number nfas_group number	On a different channelized T1 controller, configure the NFAS backup D channel to be used if the primary D channel fails.
5400(config-controller)# pri-group timeslots 1-24 nfas_d none nfas_interface number nfas_group number	On other channelized T1 controllers, configure a 24 B channel interface, if desired. (Optional)

Take a Channel or Interface Out of Service

You can take a specified channel or an entire PRI interface out of service or put it into one of the other states that is passed in to the switch.

To do so, complete one of the following tasks in interface configuration mode:

Command	Purpose
5400(config-controller)# isdn service dsl number b_channel number state state-value	Take an individual B channel out of service or set it to a different state.
5400(config-controller)# isdn service dsl number b_channel 0 state state-value	Set the entire PRI interface to the specified state.

These are the supported state values:

• 0--In service

• 1--Maintenance

• 2--Out of service

Verify

• Monitor NFAS groups by entering the show isdn nfas group number command:

Configuring the D Channels for ISDN Signaling

The ISDN D channels carry the control and signaling information for ISDN calls--for both circuit-switched data calls and analog modem calls. All incoming ISDN analog modem calls that come in on an ISDN PRI receive signaling information from the ISDN D channel.

When you configure ISDN PRI on the CT1 or CE1 controller (see "Configuring ISDN PRI"), in effect you automatically create a serial interface that corresponds to the PRI group time slots. This interface is a logical entity that is associated with the specific controller. After the serial interface is created, you must configure the D channel serial interface. The configuration applies to all the PRI B channels (time slots) for that pri group.

Note   When you configure your CT1 controller for an NFAS backup D channel, a serial interface is automatically created only when your primary D channel fails. See "Configuring ISDN NFAS on CT1 PRI Groups."

Configure

	Command	Purpose
Step1	5400>enable Password: password 5400#	Enter enable mode (also called privileged EXEC mode) and enter the password. You have entered enable mode when the prompt changes to 5400#.
Step2	5400#configure terminal Enter configuration commands, one per line. End with CNTL/Z. 5400(config)#	Enter global configuration mode. You have entered global configuration mode when the prompt changes to 5400(config)#.
Step3	5400(config)#interface serial 1/0:23 5400(config-if)#	Enter serial interface configuration mode. After configuring the CT1 controller, a corresponding D channel serial interface is created instantly. For example, serial interface 1/0:23 is the Dchannel for CT1 controller 1. You must configure each serial interface to receive incoming and send outgoing modem signaling. Note   On a CE1 PRI line, the serial interface is 1/0:15.
Step4	5400(config-if)#ip address 172.16.254.254 255.255.255.0	Assign an IP address and subnet mask to the interface.
Step5	5400(config-if)#isdn incoming-voice modem	Configure all incoming voice calls to go to the modems.
Step6	5400(config-if)#dialer-group 1	Assign serial interface to dialer group1. The dialer group number is used with the dialer-list command to determine which packets meet the criteria specified by the dialer-list command and activate the ISDN connection.
Step7	5400(config-if)#encapsulation ppp	Changes the default to encapsulation ppp so you can enter ppp commands.
Step8	5400(config-if)#ppp multilink	Enable PPP1 multilink on the serial interface.
Step9	5400(config-if)#ppp authentication chap pap	Enable CHAP2 and PAP3 authentication on the serial interface.
Step10	5400(config-if)# peer default ip adress pool default	Support dial-in PC clients.
Step11	5400(config-if)#Ctrl-Z 5400#	Return to enable mode.

1PPP = Point-to-Point Protocol. 2CHAP = Challenge Handshake Authentication Protocol. 3PAP = Password Authentication Protocol.

Configuring E1 R2 Signaling

R2 signaling is an international signaling standard that is common to channelized E1 networks. You can configure a channelized E1 interface to support different types of R2 signaling, which is used in older analog telephone networks.

Note   The Cisco implementation of R2 signaling has 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 collection. 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 assigned to router B, the ANI number is assigned to router A. Also, note that ANI is similar to Caller ID.

---

Tips If the connection does not go up, check the following:

---

• Loose wires, splices, connectors, shorts, bridge taps, and grounds

• Backwards transmit and receive

• Mismatched framing types (for example, CRC-4 and no-CRC-4)

• Transmit and receive pair separation (crosstalk)

• Faulty line cards or repeaters

• Noisy lines (for example, power and crosstalk)

If you see errors on the line or the line is going up and down, check the following:

• Mismatched line codes (HDB3 versus AMI)

• Receive level

• Frame slips because of poor clocking plan

When the E1 controller comes up, you will see the following message:

%CONTROLLER-3-UPDOWN: Controller E1 0, changed state to up

Configuring Clocking

The Time-Division Multiplexing (TDM) bus on the Cisco AS5400 backplane can receive an input clock from one of four basic sources on the Cisco AS5400:

• An AS54-DFC-8CT1/CE1 (8PRI CT1/CE1) card

• An AS54-DFC-CT3 card

• An external T1/E1 clock source feed directly through the Building Integrated Timing Supply (BITS) interface port on the motherboard

• Free-running clock provides clock from an oscillator

---

Note   Building Integrated Timing Supply (BITS) is a single building master timing supply. BITS generally supplies DS1 and DS0 level timing throughout an office. In North America, BITS are the clocks that provide and distribute timing to a wireline network's lower levels.

---

Dial Feature Card Ports

The TDM bus can be synchronized with any DFC cards. On the 8PRI CT1/CE1 DFC, each port receives clock from the T1/E1 line. The CT3 DFC uses an M13 multiplexer to receive the DS1 clock. Each port on each DFC trunk slot has a default clock priority. Also, clock priority is configurable through the dial-tdm-clock priority CLI command.

External Clock

The TDM bus can be synchronized with an external clock source that can be used as an additional network reference. If no clocks are configured, the system will use a primary clock through a software-controlled default algorithm. If you want the external clock as the primary clock source, you must configure it using the dial-tdm-clock priority CLI command; the external clock is never selected by default.

Free-Running Clock

If there is no good clocking source from a DFC card or an external clock source, then the free running clock from the local osciallator is used through the dial-tdm-clock priority CLI command.

The following table lists commands to help you configure the clock source and clock source priority used by the TDM bus:

	Command	Purpose
Step1	5400>enable Password: password AS5800-1#	Enter the enable command. Enter your password. You are in privileged EXEC mode when the prompt changes to 5400#.
Step2	5400#configure terminal Enter configuration commands, one per line. End with CNTL/Z. AS5800-1(config)#	Enter global configuration mode by typing the configure command. The example is using the terminal configuration option. You are in global configuration mode when the prompt changes to 5400(config)#.
Step3		Depending on your configuration:
a.	5400(config)# dial-tdm-clock priority priority# {external | freerun | slot/ds1 port} or	Configure the 8PRI CT1/CE DFC clock priority, trunk slot and port that is providing the clocking source. Priority range is defined as a value between 1 and 99. DFC slot is defined as a value between 1 and 7. DS1 port number controller is defined as a value between 0 and 7. Note   DS1 port specifies T1 port.
b.	5400(config)# dial-tdm-clock priority priority# {external | freerun | slot/ds3 port:ds1 port}	Configure the CT3 DFC clock priority, trunk slot and port that is providing the clocking source. Priority range is defined as a value between 1 and 99. DFC slot is defined as a value between 1 and 7. DS3 port specifies the T3 port. DS1 port number controller is defined as a value between 1 and 28. Note   Clock with priority of 100 cannot drive the TDM clock.
Step4	5400(config)#Ctrl-Z 5400#	Press the Return key to verify your command registers, then type Ctrl-Z to return to privileged EXEC mode.
Step5	5400#copy running-config startup-config	Save your changes when ready.

Configuration Examples

In the following example, BITS clock is set at priority 1.

5400(config)# dial-tdm-clock priority 1 external 
5400(config)# exit
5400#
 

In the following example, a trunk clock from an 8 PRI CT1 DFC is set at priority 2 and uses slot 4 and ds1 port (controller) 6.

5400(config)# dial-tdm-clock priority 2 4/6
5400(config)# exit
 

In the following example, a trunk clock from a CT3 DFC is set at priority 2 and uses slot 1, ds3 port 0, and ds1 port 19.

5400(config)# dial-tdm-clock priority 2 1/0/:19
5400(config)# exit
 

In the following example, free running clock is set at priority 3.

5400(config)# dial-tdm-clock priority 3 free
5400(config)# exit

Verify

You can verify the system primary and backup clocks; status of all trunk DFC controller clocks; information and history of last 20 TDM clock changes and the events that caused them.

• Verify your default system clocks using the show tdm clocks command:

Configuring the Asynchronous Group Interface

You can assign the asynchronous interfaces to a group so that you can configure them as a group, instead of individually.

TimeSaver Because there are so many asynchronous interfaces on the access server, configuring them as a group will save you time.

Configure

	Command	Purpose
Step1	5400>enable Password: password 5400#	Enter enable mode (also called privileged EXEC mode) and enter the password. You have entered enable mode when the prompt changes to 5400#.
Step2	5400#configure terminal Enter configuration commands, one per line. End with CNTL/Z. 5400(config)#	Enter global configuration mode. You have entered global configuration mode when the prompt changes to 5400(config)#.
Step3	5400(config)#interface group-async 1 5400(config-if)#	Place all asynchronous interfaces in a single group, so that you configure the same parameters quickly on all interfaces at one time.
Step4	5400(config-if)#group-range 1/1 1/48 Building configuration... 5400(config-if)#	Define the group range of the interface. The number you use with the group-range command depends on the number of asynchronous interfaces you have on your access server. That is, if your access server has 48 asynchronous interfaces, you can specify group-range 1/1 1/48. If 60, specify group-range 1/1 1/60.
Step5	5400(config-if)#Ctrl-Z 5400#	Return to enable mode.

Verify

To verify your group interface configuration:

• Enter the show interface async command to check if the protocol is up:

• Enter the show dialer map command to make sure the dialer map is up:

5400# show dialer maps
Dynamic dialer map ip 10.2.1.1 name customer1 () on As4/87
Static dialer map ip 21.0.0.2 name customer2 (22222) on Se3/3:23

---

Tips If you are having trouble:

---

• Enter the show async status command to check for errors and local and remote addresses:

• You can also view debug messages for PPP negotiation and authentication using the debug ppp negotiation and debug ppp authentication commands. When you finish viewing the messages, turn off the messages by entering no debug ppp negotiation and no debug ppp authentication commands.

Configuring the NextPort Dial Feature Card

Rather than the more traditional line/modem one-to-one correspondence, lines are mapped to a Service Process Element (SPE) that resides on the NextPort DFC (also referred to as the AS54-DFC-108NP). Associated SPE firmware serves a function similar to modem code on a MICA modem.

One SPE provides modem services for six ports, with additional ports per SPE. Busyout and shutdown can be configured at the SPE or port level. The NextPort DFCs available for the Cisco AS5400 provide 18 SPEs for a total of 108 ports per DFC.

The Cisco AS5400 NextPort DFC performs the following functions:

• Converts pulse code modulation (PCM) bitstreams to digital packet data.

• Forwards converted and packetized data to the main processor, which examines the data and forwards it to the backhaul egress interface.

• Supports all modem standards (such as V.34 and V.42bis) and features, including dial-in and dial-out.

Note   This release supports modem and digital service types only. For further information in this document, refer to "Managing and Troubleshooting the NextPort Dial Feature Card." For detailed information about NextPort Cisco IOS CLI commands, refer to the NextPort Port Service Management for Cisco AS5400 Universal Access Server.

SPE Firmware

SPE firmware is automatically downloaded to a NextPort DFC from the Cisco AS5400 when you boot the system for the first time or when you insert a NextPort DFC while the system is operating. When you insert DFCs while the system is operating, the Cisco IOS image recognizes the cards and downloads the required firmware to the cards.

The SPE firmware image is bundled with the access server Cisco IOS image. The SPE firmware image uses an auto detect mechanism, which enables the NextPort DFC to service multiple call types. An SPE detects the call type and automatically configures itself for that operation. The firmware is upgradeable independent of Cisco IOS upgrades, and different firmware versions can be configured to run on SPEs in the same DFC.

The NextPort DFC supports the modem standards and features listed in Table 3-7.
