2Modem/DSU Commands
2-1916800-A2-GB31-20 January 1997
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.
