DCP Operation

Loc Analog Loop

This test is not available when using V.34 modulation in Multiport mode.

Loc Analog Loop performs a local analog loopback (CCITT V.54 Loop 3), Figure 3-4, that verifies modem operation as well as the connection between the DTE and modem. The modem must be offline and in Synchronous or Asynchronous Direct mode to perform this test, otherwise Invalid Command appears.

NOTE

If you are performing a Local Analog Loop test on a TMp modulation that is running a test pattern with a constant flow of data, you must toggle the RTS switch off and then on to allow the modem to train up.
