8-12 MTR3000 Wireline: Functional Theory Of Operation
WL HLGT ALC Mode This field, if enabled, automatically adjusts the transmit audio up to
-4/+6dB to compensate for changes in the line levels. This adjustment is
made when high level guard tone (HLGT) is detected. As such, the ALC
cannot be used with the DC Remote Control or no remote control modes.
WL Monitor Mode This field defines the behavior of the Monitor function as either latching or
momentary. When set to latching, the base station/repeater receiver’s
squelch is opened until the next High Level Guard Tone (HLGT) is sent via
the console. When set to momentary, the base station/repeater receiver’s
squelch is opened for four seconds.
WL PTT Dropout Timer This field specifies the allowed hold over time after the loss of low level
guard tone (LLGT) before the base station/repeater dekeys. This
parameter allows for momentary LLGT loss without dekeying the base
station/repeater. LLGT is a tone generated by the console or deskset which
signals the Wireline to issue a push to talk (PTT) to the base station/
repeater.
WL Revert Channel This field selects the revert channel of the base station/repeater. The revert
channel is the channel that the base station/repeater will return to after a
call is completed. If the revert channel is set to "no revert", then after the
call is complete, the base station/repeater will remain on the channel of the
completed call.
