Using the Test Port

Trunk Card Bantam Jacks

The test port is a set of bantam jack connectors located at the bottom of the CT3 front panel (see

Figure 3-4). The bantam jacks 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 or to monitor

an individual T1 circuit in monitor mode.

Drop-and-Insert Mode

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 particular T1 line to the test port, follow these steps:

Enable drop-and-insert mode by entering the test trunk drop-insert on privileged EXEC command as

Step 1

follows:

AS5800# test trunk drop-insert on

Note

Step 2

Push and quickly release the push button below the LED to toggle to the port number. The push button

is labeled "MONITOR #" in Figure 3-3.

Note

Push and hold the push button for two or more seconds.

Step 3

The letter "D" (indicating drop-insert) is displayed in the front panel LED, indicating that the particular

T1 line has been dropped to the test port.

Note

Disable the drop-and-insert mode after testing the T1 lines. We recommend that you disable

Step 4

drop-and-insert mode to prevent accidental use of the push button on the CT3 board.

To disable drop-and-insert mode, enter the test trunk drop-insert off privileged EXEC command as

follows:

AS5800# test trunk drop-insert off

3-8

In drop-and-insert mode, the T1 line is dropped out of service. To prevent accidental use of the push

button in drop-and-insert mode, use the test trunk drop-insert privileged EXEC command to

disable the drop-and-insert mode on the specified T3 controller.

In monitor mode, you can monitor only the ingress side of the T1 line. The T1 line being monitored

is not disrupted, and the line maintains its HDLC and modem connections through TDM.

The shelf/slot/unit identifies the T1 to the CT3 controller.

You must release the push button within 2 seconds to advance through the port

numbers (from 1 to 28). After port 28, the display returns to port 1.

To select another port number, press the push button again and hold it for two or

more seconds. You can now toggle to another port number.
