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.
