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.
