Modem/DSU Commands

Remote Digital Loopback (rdl)

(Disruptive)

Use the rdl command to place a remote DATAPHONE II Direct Distance Dial (DDD) modem in or out of a digital loopback state. Digital loopback disconnects the data terminal equipment interface leads from the modem and links the modem's receiver to its transmitter to create an internal loop for remote testing.

The rdl command provides two options, loopback and release. The loopback option places the modem in remote digital loopback testing. The testing will continue until you execute the rdl command again using the release option, or until you execute an Abort (abort) command to abort the test.

For most commands, NMS enables you to specify the destination for the command's results and schedule its execution. If the last page of the input form cannot accommodate the Destination for results and Schedule execution fields, an additional page is provided. For a complete description of these fields, refer to Chapter 1, Introduction.
