Carrier Access Access Navigator Manual De Usuario

Loop command sent to remote.

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.

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.

To check remote loopback status, use the read remote loopback 

command. See Read Remote Loopback on 

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.
