DISA Card (KX-T96191) Functions
1.
4 OGM trunks.
OGM duration: 30 seconds,
OGM Capacitor Backup: 5 days.
The number of OGM: 1,
Recording Algorithm: ADPCM.
2.
4 CO-to-CO speech paths without amplifier.
A CO-to-CO speech path consists of up-path and down-path.
Up-path is from call-originate CO to call-answer CO, and 1 DTMF receiver and one speech
end detector is connected to it.
Down-path is from call-answer CO to call-originate CO and one speech end detector is
connected to it.
3.
Speech end detector.
Speech end detector detects call progress tones.
DISA Card (KX-T96191) Operation
1.
The LED indicator on the DISA card lights when the system reset or DISA local reset
occurs.
AGC Card (KX-T96193) Functions
Automatic Gain Control card
1.
4 CO-to-CO speech paths with AGC amplifier and Echo-Suppressor.
A CO-to-CO speech path consists of up-path and down-path, up-path is from call-originate
CO to call-answer CO, and AGC amplifier is inserted and speech end detector is connected.
The Maximum amplification of AGC is 10 dB.
The Echo-Suppressor is inserted in a CO-to-CO speech path.
2.
4 DTMF receivers.
DTMF transceiver is used as DTMF repeater.
So, AGC card microprocessor controls DTMF repeater.
3.
8 Speech End Detectors.
Speech end detector of AGC is quite the same as that of the DISA card.
AGC Card (KX-T96193) Operation
The LED indicator on the AGC card lights when the system reset or AGC local reset occurs.
RMT Card (KX-T96196) Functions
Remote Circuit card
Modem (300/1200 bps) for remote administration.
RMT Card (KX-T96196) Operation
The LED indicator on the RMT card lights when the system reset or RMT local reset occurs.
