Switches
The MPDM is equipped with the following switches:
■ ORIGINATE/DISCONNECT — This switch is located on the front panel. It
is used when originating and disconnecting a call from a terminal that does
not have a BREAK key.
■ SELF-TEST — This switch is located behind the front faceplate. It is used
to perform the self-test.
■ LOC LOOP/REM LOOP — This switch is located behind the faceplate. It is
used to perform the Local loop test or Remote loop test.
NOTE:
If you are using the Video Teleconferencing MPDM or the High Speed
Synchronous MPDM preassembled package, and the OFF/ANET switch is
set to ANET), the user-activated Remote Loop will not function since
Remote Loop requires Mode 2 handshake operation.
■ Options — The option switches are located behind the front faceplate.
There are two Dual In-line Package (DIP) option switches, one with
10 positions, the other with 12 positions. Twenty-one of the positions are
used to set the options. The other is a spare reserved for future use.
The RS-232-C interface card has eight DIP switches to set its options.
