Chapter 5 - Testing the Modem

5.6 Digital Loopback Test (Remote/Automatic)
(Synchronous Mode)

This test must be run when you have a data connection with another
modem. To initiate the Digital Loopback Test (remote/automatic), DIP-
Switch #9 must be in the DOWN position, then place DIP-Switch #16 in the
opposite position it is currently (the modem requires a state of change in
Switch #16 to activate Loopback tests). Once you receive an OK message
from your modem (if responses are enabled), the local modem is placed in
Digital Loopback mode.

To exit the Digital Loopback Test (remote/automatic), pull out and then
reinsert modem card into modem card cage.
