Type II caller ID information — The Si2494/39 will display “+VCDIR:” followed by raw caller
ID information including checksum.
+VDR = n
Distinctive Ring.

1,0
Enable distinctive ring. The ISOmodem will report DROF and DRON result
codes only. DROF and DRON are reported in 100 ms units.
1,x
Enable distinctive ring. The ISOmodem will report DROF and DRON result
codes as well as well as a RING result code x/10 seconds after the falling
edge of a ring pulse. DROF and DRON are reported in 100 ms units.
+VGR
Receive Gain Selection.
The <gain> parameter has a range of 112-134 with 128 being the nominal value. This repre-
sents a range of -48 dB to 18 dB. The default is 128 (0 dB). This command is used to control
the receive gain at the DTE from either the Si3000 Codec or the DAA. The purpose is to
adjust the DTE receive gain for the TAM voice stream during idle state.
+VGT
Transmit Gain Selection.
The <gain> parameter has a range of 112-134 with 128 being the nominal value. This repre-
sents a range of -48 to 18 dB. The default is 128 (0 dB). This command is used to control the
transmit gain at the DTE to either the Si3000 Codec or the DAA. The purpose is to adjust the
DTE transmit gain for the TAM voice stream during idle state.
+VIP
Load Voice Factory Defaults.
+VIT
DTE/DCE Inactivity Timer.
The <timer> parameter has a range of 0–255 with units of seconds.
The default is 0 (disable).
