Channelized T3 Feature Card


This chapter describes the channelized T3 (CT3) feature card and includes the following sections:

Overview

The CT3 feature card provides physical line termination for a channelized T3 ingress trunk line. It uses an onboard multiplexer to multiplex 28 channelized T1 lines into a single channelized T3 line. (See Figure 4-1.)

Figure 4-1 CT3 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.


The CT3 feature card provides physical line termination for up to 672 DS0 channels and uses onboard High-Level Data Link Control (HDLC) controllers to terminate digital (ISDN) calls.

You can use the bantam jack ports on the feature card to monitor a T1 line or to test any of the individual T1 channels in drop and insert mode.

You can install a CT3 feature card in any feature card slot in a universal gateway chassis.

Online Insertion and Removal of the CT3 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 CT3 Feature Card

To remove the CT3 feature card, follow these steps.


Note The OIR procedure for the CT3 feature card is similar to that for the T1 or E1 feature card. See the "Online Insertion and Removal Example for the T1 or E1 Feature Card" section on page 3-6 for an example of the output during OIR of an E1 feature card.



Step 1 Determine which slot the feature card is in (see Figure 4-2 and Figure 4-3) 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 4-3 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 the 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 feature card that is associated with the CT3 feature card.

Router# show controller t3 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.


Note The OIR procedure for the CT3 feature card is similar to that for the T1 or E1 feature card. See the "Online Insertion and Removal Example for the T1 or E1 Feature Card" section on page 3-6 for an example of the output during OIR of an E1 feature card.


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 4-4 and Figure 4-5.)

Figure 4-5 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 4-6 and Figure 4-7.)


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

Figure 4-7 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 a feature card slot on the carrier card is to remain empty, install a blank cover over the open feature card slot to ensure proper airflow inside the chassis. (See Figure 4-8.)

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



Note When you replace a feature card with a new feature card of the same type in the same slot, 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 CT3 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 4-9 and Figure 4-10.)

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 4-11 and Figure 4-12.)

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