Chapter 5 - Testing the Modem
5.5 Digital Loopback Test (Local/Manual)
(Synchronous Mode)
This test must be run when you have a data connection with another
modem. To initiate the Digital Loopback Test (local/manual), DIP-Switch #9
must be in the UP 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 (local/manual), pull out and then reinsert
modem card into modem card cage.
