Page: 48 / 256

NOTE: The CT3/T3-F0 line module supports only the 2^11 , 2^15 , and 2^20-O153 options.
•
0s —Repetitive test pattern of all zeros, 00000...
•
1s —Repetitive test pattern of all ones, 11111...
•
2^11 —Pseudorandom test pattern, 2047 bits in length
•
2^15 —Pseudorandom test pattern, 32,767 bits in length
•
2^20-O153 —Pseudorandom test pattern, 1,048,575 bits in length
•
2^20-QRSS —Pseudorandom QRSS test pattern, 1,048,575 bits in length
•
2^23 —Pseudorandom test pattern, 8,388,607 bits in length
•
alt-0-1 —Repetitive alternating test pattern of zeros and ones, 01010101...
NOTE: The BERT patterns supported when testing the T1 layer vary depending on the
line module and I/O module assembly you are using.
•
Specify the duration of the test in the range 1–1440 minutes.
•
Optionally, specify the unframed keyword to overwrite the framing bits.
•
Example
host1(config-controll)# t1 2 bert pattern 2^11 interval 10 unframed
•
Use the no version to stop the test that is running.
•
See t1 bert.
t1 loopback
•
Use to configure a loopback.
•
Specify one of the following options:
NOTE: The CT3/T3-F0 line module does not support the remote line inband option.
•
local —Loops the router output data back toward the router at the T1 framer; on
supported line modules, also sends an alarm indication signal (AIS) out toward the
network
•
network { line | payload }—Specify the line keyword to loop the data back toward
the network before the T1 framer and automatically set a local loopback at the HDLC
controllers. Specify the
payload keyword to loop the payload data back toward the
