CLI Command List

Message: Loop command sent to remote.

Send Remote T1Drop Payload 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 payload loopup command should cause the remote Access Bank II to perform a payload loopback on the T1 Drop interface. This takes the received T1 Drop DS0s, loops them in the framer, and sends them back to the T1 Drop output (see Figure 18-19). To loopdown the interface, use the send remote loopdown command.
