Notes:
231 and 233: Signalling of connection start or end:
0 None signalling
1 Current break for time specified by par. 232 or 234
2 Polarity change (without return) Not recommended.
3 Polarity change with return, time of inverted polarity specified by parameter 232 or 234
4 Frequency impulse (typically 16 kHz), length see parameter 232 or 234, frequency see
parameter 235
5 Polarity change (without return, always): parameter 231 - polarity is changed on the
beginning of
both incoming and outgoing calls, parameter 234 - polarity is changed on
the end of call even if PBX hangs up first.
NOTE: Only for GSM calls! During PSTN calls, signalling is not generated by GSM
gateway, it is only passed thru from PSTN, if present.
