Using the Bantam Jack Ports to Monitor T1, E1, and CT3 Feature Cards

Using the Bantam Jack Ports to Monitor T1, E1, and CT3 Feature

Cards

Monitor mode is available on the T1, E1, and CT3 feature cards. If a T1 controller does not come up, or

if a large number of errors are associated with a particular controller, you might be able to use the test

port to determine whether the problem is in the feature card or in an external T1 line. by using the test

port. The test port is a set of bantam jack ports located on the front panel of the T1, E1, and CT3 feature

cards. (See

Figure 7-7

.)

Figure 7-7

Bantam Jack Ports

In monitor mode, you can monitor only the ingress side of the T1 line without disrupting that line.

The bantam jack ports located on the front panel of the feature cards allow the connection of an external

test device (for example, a FIREBERD test device) to monitor the individual T1 circuits in monitor

mode. Use software commands to select a T1 line. For information on software commands, see the

Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide

.

Passive monitoring equipment is used to listen on the TX MON and RX MON jacks during regular

operation to detect T1 errors.

Connecting test equipment to the following bantam jack ports provides various functions:

•

TX MON can monitor signals coming out of the test port without interrupting normal data

transmission.

•

RX MON can monitor signals going in to the test port without interrupting normal data transmission.

Using Drop and Insert Mode on the CT3 Feature Card

The bantam jack ports located on the front panel of the CT3 feature card allow the connection of an

external test device (for example, a FIREBERD test device) to test any of the 28 individual T1 circuits

in drop and insert mode. Once drop and insert mode is enabled, a T1 circuit can be dropped out of service

by using the push button on the CT3 feature card.

The

test trunk drop-insert

privileged EXEC command is used to enable or disable drop and insert mode

on a T3 controller. When the system initially boots up, the drop and insert mode is disabled on all T3

controllers.

To drop a T1 circuit to a test port, follow these steps:

Step 1

Enable drop and insert mode by entering the

test trunk drop-insert on

port-number

privileged EXEC

command as follows:
