CLI Language Reference
CLI Command List
Message:
Loop command sent to remote.
Send Remote RS232 TSI 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 RS-232 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 rs232 tsi network loopup
command should cause the
remote Access Bank II to perform a network loopback on the RS-232 data. This takes
the received RS-232 DS0 from the network T1, loops it in the Time Slot Interchange
(TSI), and sends it back to the T1 output (see Figure 18-13).
The
send remote rs232 tsi equipment loopup
command should cause the
remote Access Bank II to perform an equipment loopback on the RS-232 signal. This
takes the received DS0 from the RS-232 equipment interface, loops it in the Time Slot
Interchange (TSI), and sends it back to the RS-232 output (see Figure 18-14). To
loopdown the interface, use the
send remote loopdown command.
