5.5Digital 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.
