Carrier Access Access Navigator Remote loopdown command, Example send remote 9 t1 tsi loopup

CLI Language Reference

CLI Command List

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 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 18-75and 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 <n> t1 tsi loopup command should cause the remote Access Bank II to perform a Time Slot Interchange (TSI) loopback. This takes the received DS0 data, loops it in the TSI, and sends it back to the T1 output (see Figure 18-17). To loopdown the interface, use the send remote loopdown command.
