Description
Pulse dial make time (ms units).
Pulse dial interdigit time (ms units).
DTMF power level—16-bit format is 0x0(H)(L)0 where H is the
(–)dBm level of the high-frequency DTMF tone and L is the (–)dBm
level of the low-frequency DTMF tone. Note that twist may be speci-
fied here.
DTMF on time (ms units).
DTMF off time (ms units).
Ring frequency high—Maximum frequency ring to be considered a
valid ring. RGFH = 2400/(maximum ring frequency).
Ring delta
Ring cadence minimum ON time in seconds multiplied by 2400.
Ring cadence maximum total cadence in seconds multiplied by
2400.
This is a bit-mapped register.
Pre-dial delay-time after ATD command that modem waits to dial
(ms units). The Si2456/33/14 stays on-hook during this time.
Flash Hook Time. Time corresponding with “!” or “&” dial modifier
that the Si2456/33/14 goes on-hook during a flash hook (ms units).
Loop current debounce on time (ms units).
Loop current debounce off time (ms units).
Transmit level (1 dB units)—Sets the modem data pump transmitter
level. Default level of 0 corresponds to –9.85 dBm.
Transmit level = –(9.85 + XMTL) dBm. Range = –9.85 to –48.
