5-3 Ring
When you connect WellGate 2540 FXO gateway Lines to local PABX’s extension
or PSTN switch, please configure proper
Ring Cadence (Ring ON time and Ring
OFF time)
according to
the PABX or PSTN ring Cadence specification.
Without configuring Ring Cadence to FXO gateway properly according to PABX
or PSTN Ring Cadence, FXO may detect Ring signal in a strange behavior and
cause abnormal operation.
WellGate 2540 factory default Ring Cadence setting is 1 seconds ON, 2
seconds OFF. Some PABX or PSTN provides 1 second ON and 3 seconds OFF
Ring Cadence. In this case, please configure WellGate 2540 Ring Cadence to 1
second ON and 3 seconds OFF to match incoming Ring signal. (See Figure 5-3
Ring setting.)
Note:
if you have no idea what is the PABX or PSTN ring cadence, please to
change the ring on and ring off to
8000
. When have an incoming call which
WellGate 2540 can’t pick up it.
