low: loop interruptiion time for collect calls (incoming traffic)
high: feeding interruption from PSTN (incoming traffic)
low: polarity reversal from PSTN (incoming traffic)
high: feeding interruption from PSTN (outgoing traffic)
low: polarity reversal from PSTN (outgoing traffic)
high: answer loop (incoming traffic)
low: release recognition by feeding interruption from PSTN before answer (incoming traffic)
high: loop start and earth calling
low: charge or answer pulse (outgoing traffic)
version ≠ V2.3 (SICOFI -Power ON only in
high: ground pulse to PSTN (l1)
low: dial tone supervision (outgoing traffic)
high: Delayed activation of line supervision
low: last look noise suppression (multiple of 4 ms)
** The parameter P12, short timers S1, S2 and S14 are used for 12kHz and 16 kHz charge recognition.
Any value changing of one of those parameter can influence the other parameter.
