Overview

You can install a T1 or E1 feature card in any feature card slot of the universal gateway chassis. (See Figure 3-1 through Figure 3-3.)

Figure 3-1 2-Port T1 or E1 Feature Card

Figure 3-2 4-Port T1 or E1 Feature Card

Figure 3-3 8-Port T1 or E1 Feature Card


Note The Cisco AS5350XM and Cisco AS5400XM universal gateways each support only one type of WAN feature card at a time. See Chapter 7, "Troubleshooting," for more information.


Each T1 or E1 feature card provides physical line termination for multiple DS-0 channels and uses onboard HDLC controllers to terminate digital (ISDN) calls. For network specifications, see Table 3-1 and Table 3-2. You can use the bantam jack ports on the feature card to monitor a line.

Online Installation and Removal of the T1 or E1 Feature Card

To remove a feature card without dropping any calls or connections, you will need to take the feature card out of service by using the busyout command to disable the feature card. The busyout command is executed on a per-feature card basis and will disable the card after waiting for the active services to terminate.

If there are active calls on the feature card after you execute the busyout command, wait for the calls to drop. To view the status of the termination process, use the show busyout command.


Caution The online installation and removal (OIR) of new cards should be done only during times of low CPU utilization, such as during maintenance.


Caution To avoid erroneous failure messages, remove or insert only one feature card at a time.

When you replace a feature card in a slot with a new feature card of the same type, the system software recognizes the new feature card and brings up the trunk interfaces automatically.

If you replace the existing feature card with a new feature card of a different type, you must reconfigure the system. For configuration details, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide.

Removing the T1 or E1 Feature Card

To remove the T1 or E1 feature card, follow these steps.


Note An example showing the output from each command is provided after the procedure. See the "Online Insertion and Removal Example for the T1 or E1 Feature Card" section.



Step 1 Determine which slot the feature card is in (see Figure 3-4 and Figure 3-5) by entering the show chassis slot command in privileged EXEC mode:

Router# show chassis slot


Note These commands are not valid for slot 0. Slot 0 is the motherboard.


Figure 3-4 Slot Numbering on the Cisco AS5350XM Chassis

Figure 3-5 Slot Numbering on the Cisco AS5400XM Chassis

Step 2 Initialize the software busyout procedure by entering the busyout command:

Router# busyout slot-number

Step 3 Check busyout status for the slot, by entering the show busyout command.

Router# show busyout slot-number

Step 4 You can use the clear port command to immediately disable active calls on a universal port, dial-only, or voice feature card. For more information on the universal port or dial-only feature card, see Chapter 5, "Universal Port and Dial-Only Feature Cards." For more information on the voice feature card, see Chapter 6, "Voice Feature Card." Use the show controller command to show the card that is associated with the T1 or E1 feature card.

Router# show controller t1/e1 slot-number/control-number timeslot timeslot-number
Router# clear port slot-number/port number


Note The clear port command applies only to universal port, dial-only, or voice feature cards.


Step 5 Verify that the OK/MAINT LED is off; this indicates that the feature card is offline and ready to be removed.


Note The OK/MAINT LED is green before you enter the busyout command. After you enter the busyout command, the LED changes to yellow. The LED turns off after all calls are disconnected and resources are taken out of service, indicating that busyout is complete.


Step 6 Attach an ESD-preventive wrist strap.


Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001


Step 7 Disconnect all interface cables from the feature card and secure them out of the way.

Step 8 Loosen the two captive screws that secure the feature card to the chassis until each screw is free of the chassis. (See Figure 3-6 and Figure 3-7.)

Figure 3-6 Loosening the Captive Screws on the Cisco AS5350XM Universal Gateway

Figure 3-7 Loosening the Captive Screws on the Cisco AS5400XM Universal Gateway

Step 9 Grasp the feature card handle with one hand. Pull the card toward you until the card slides free of the chassis. Grasp the ventilated metal cover with your other hand to support and guide the feature card out of the slot. (See Figure 3-8 and Figure 3-9.)


Caution Avoid touching any pins or circuit board components when you remove or install a feature card.

Figure 3-8 Removing the Feature Card from the Cisco AS5350XM Universal Gateway

Figure 3-9 Removing the Feature Card from the Cisco AS5400XM Universal Gateway

Step 10 After you remove the feature card from the chassis, set it aside on an ESD-preventive mat.

Step 11 If the feature card slot is to remain empty, install a blank cover over the open feature card slot to ensure proper airflow inside the chassis. (See Figure 3-10.)

Installing the T1 or E1 Feature Card


Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001



Warning The E1 interface card may only be installed in an ACA-permitted customer equipment or a Data Terminal Equipment (DTE) that is exempted from ACA's permit requirements. The customer equipment must only be housed in a cabinet that has screw-down lids to stop user access to overvoltages on the customer equipment. The customer equipment has circuitry that may have telecommunications network voltages on them. Statement 90



Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open. Statement 89



Note When you replace a feature card in a slot with a new feature card of the same type, the system software recognizes the new feature card and brings up the trunk interfaces automatically. If you replace the existing feature card with a new feature card of a different type, you must reconfigure the system. For configuration details, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide.


To install the T1 or E1 feature card, follow these steps:


Step 1 Attach an ESD-preventive wrist strap.

Step 2 Slide the feature card into the slot until the connector pins make contact with the carrier card backplane connector. (See Figure 3-11 and Figure 3-12.)

Figure 3-11 Installing the T1 or E1 Feature Card in the Cisco AS5350XM Universal Gateway

Figure 3-12 Installing the T1 or E1 Feature Card in the Cisco AS5400XM Universal Gateway

Step 3 Align the captive screws with their holes, and seat the card completely.

Step 4 Tighten the screws to secure the feature card to the chassis. (See Figure 3-13 and Figure 3-14.)

Figure 3-13 Tightening the Captive Screws on the Cisco AS5350XM Universal Gateway

Figure 3-14 Tightening the Captive Screws on the Cisco AS5400XM Universal Gateway

Step 5 Check the card LEDs to verify that the card is working properly. For information about feature card LEDs, see Chapter 7, "Troubleshooting."



Note For information about configuring the T1 or E1 ports, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide.


Configuring Input Impedance for the E1 Feature Card

You can set the input impedance of the E1 feature card before or after running the setup script. For information on configuring the universal gateway with the setup script, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide.

Configuration

To set the input impedance for the E1 feature card, use the line-termination command.

 
Command
Purpose
Step 1
Router> enable
Password: password 
Router# 

Enters enable mode.

Enter the password. You have entered enable mode when the prompt changes to Router#.

Step 2
Router# configure terminal
Enter configuration commands, one per line. End
with CNTL/Z.
Router(config)#

Enters global configuration mode. You have entered global configuration mode when the prompt changes to Router(config)#.

Step 3
Router(config)# controller e1 0
Router(config-controller)# 

Enter the controller number on which you are configuring input impedance.

Step 4
Router(config-controller)# line-termination 
75-ohm

Sets the input impedance to 75 ohm for the controller. The factory-set default is 120 ohm. Repeat Step 3 and Step 4 for the other controllers.

Step 5
Router(config-controller)# Ctrl-Z 
Router#
%SYS-5-CONFIG_I: Configured from console by 
console

Returns to enable mode.

This message is normal and does not indicate an error.

Verification

To verify the impedance, enter the show running-config command.


Note By default, input impedance is 120 ohm. In the following example, the input impedance was successfully changed to 75 ohm using the line-termination 75-ohm command. Some of the configuration has been deleted for readability.
