CLI Language Reference
CLI Command List
Send Remote T1Drop Line Loopup
NOTE:
This command applies only to a remote Access Bank II connected
to the Access Navigator by a DS1 using Carrier Access FDL management
protocol. For normal operation, the loopback must be disabled by the
send
remote loopdown
command.
NOTE:
Only one port of the Access Bank II can be looped up at a time. If a
loopup command is received for a second port, the first port will be looped down
automatically before the second port is looped up.
NOTE:
To check remote loopback status, use the
read remote loopback
command. See Read Remote Loopback on page 18-51 .
Purpose:
Sends an out-of-band (FDL) message to a remote Access Bank II over the Access
Navigator DS1. It is used to verify T1 Drop signal processing.
When the operator enters a
send remote
command, the Access Navigator transmits
a message over the Carrier Access FDL management channel of the drop DS1. The
Access Navigator’s drop DS1 is the Access Bank’s T1 connection.
The
send remote t1drop line loopup
command should cause the remote
Access Bank II to perform a line loopback on the T1 Drop output. This takes the
received T1 Drop DS1 signal, loops it in the framer, and sends it back to the T1 Drop
output (see Figure 18-18). To loopdown the interface, use the
send remote loopdown
command.
