Configuring Unchannelized mode for the Cisco PA-MC-2T3+
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:
•
•
Examples follow:
•
•
You can terminate a BER test during the specified test period with the no bert command.
Note
OL-3526-05
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.
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
