Send Remote RS232 Line 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 CAC FDL channel of the drop DS1. The Access Navigator’s drop DS1 is the Access Bank’s T1 connection.

The send remote rs232 line loopup command should cause the remote Access Bank II to perform a line loopback in the RS-232 interface. This takes the received RS- 232 data signal, loops it back in the RS-232 interface, and sends it back to the RS-232 output (see Figure 18-13). To loopdown the interface, use the send remote loopdown command.
