Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

Configuring an Unchannelized T3 Link

Sending a BER Test Pattern on the T3 Line

You can send a BERT pattern on the T3 line with the bert command in controller configuration mode.

bert pattern pattern interval time

where:

• pattern is:

–

0s, repetitive test pattern of all zeros (as 00000...)

–

1s, repetitive test pattern of all ones (as 11111...)

–

2^15, pseudorandom O.151 test pattern (32,768 bits long)

–

2^20, pseudorandom O.151 non-QRSS test pattern (1,048,575 bits long)

–

2^23, pseudorandom O.151 test pattern (8,388,607 bits long)

–

alt-0-1, repetitive alternating test pattern of zeros (0s) and ones (1s), (as 01010101)

• time is 1–14400 minutes.

Examples follow:

• Send a BERT pseudorandom pattern of 2^23 for 5 minutes.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0

Router(config-controller)# bert pattern 2^23 interval 5

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0

Router(config-controller)# bert pattern 2^23 interval 5

• Send a repetitive pattern of all ones for 14400 minutes (240 hours).

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0

Router(config-controller)# bert pattern 1s interval 14400

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0

Router(config-controller)# bert pattern 1s interval 14400

Note You can terminate a BER test during the specified test period with the no bert command.
