5.2.8.
Surge Protection
Thyristor is sintalled between T or R and FG protect from extraneous surge.
5.2.9.
Bell Signal Genarator and Transmission
In ringing mode, the ringing DC offset and the ringing signal are summed within SLIC/CODEC in accordance with the
programmed values.
The SLIC/CODEC supplies the line with 65 Vrms.
The bell signal is generated with VBAT supplied to the SLIC/CODEC.
programmed values.
The SLIC/CODEC supplies the line with 65 Vrms.
The bell signal is generated with VBAT supplied to the SLIC/CODEC.
5.2.10.
EXT-CID Transmission
The SLIC/CODEC generates the extension Caller ID signals (FSK signal) with the CPU board control.
The data flow is shown below.
The data flow is shown below.
1) The CPU board control signals are received.
2) PLD controls the tone generator inside SLIC/CODEC.
3) The SLIC/CODEC generates Caller ID signals (FSK).
4) Caller ID signals are sent to extension ports.
