Chapter 5 Configuring the Channelized Mode
Configuring a Channelized T3 Link
•
Set the first T1 line into network line loopback.
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
controller T3 1/0
Router(config-controller)#
t1 1
loopback network line
In the preceding example, network line loopback loops the data back toward the network (before the
T1 framer).
•
Set the first T1 line into network payload loopback.
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
controller T3 1/0
Router(config-controller)#
t1 1
loopback network payload
In the preceding examples, network payload loopback loops just the payload data back toward the
network at the T1 framer.
•
Set the first T1 line into remote line inband loopback.
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
controller T3 1/0
Router(config-controller)#
t1 1 loop remote line inband
In the preceding example, remote line inband loopback sends a repeating five-bit in-band pattern (of
00001) to the remote end, requesting that it enter into a network line loopback.
•
Set the first T1 line into remote line FDL ANSI loopback.
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
controller T3 1/0
Router(config-controller)#
t1 1 loop remote line fdl ansi
In the preceding examples, remote line FDL ANSI loopback sends a repeating 16-bit ESF data link
code word (of 00001110 11111111) to the remote end, requesting that it enter into a network line
loopback.
•
Set the first T1 line into remote line FDL bellcore loopback
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router (config)#
controller t3 1/0
Router (config-controller)#
t1 1 loop remote line fdl bellcore
In the preceding example, remote line FDL Bellcore loopback sends a repeating 16-bit ESF data link
code word (of 00010010 11111111) to the remote end, requesting that it enter into a network line
loopback.
•
Set the first T1 line into remote payload FDL ANSI loopback.
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
controller T3 1/0
Router(config-controller)#
t1 1 loop remote payload fdl ansi
In the preceding example, remote payload ANSI loopback sends a repeating 16-bit ESF data link
code word (of 00010100 11111111) to the remote end, requesting that it enter into a network
payload loopback.
