18-86 August 2003 Access Navigator - Release 1.8
CLI Language Reference
CLI Command List
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 signal processing in the Access Bank II. Payload
loopbacks can be used with unframed PRBS and QRSS test patterns (see Send DS1
Payload <pattern> on page 18-75 and Send DS1 Payload <pattern> Test on
page 18-77).
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 t1 payload loopup command should cause the remote Access
Bank II to perform a payload loopback. This takes the received DS0s from the T1,
loops them in the framer, and sends them back to the T1 output (see Figure 18-16). To
loopdown the interface, use the send remote loopdown command.

This command applies only to a remote Access Bank II connected

protocol. For normal operation, the loopback must be disabled by the send
