#VRN Ringback Never Came Timer
Used when originating a voice/audio call (
#CLS=8
) to set the “Ringback Never Came” timer
value, i.e., an amount of time (in units of 100 ms) measured from completion of dialing. If
ringback is not detected within this period, the modem assumes the remote has picked up the
line and switches to Online Voice Command Mode.
VRN?
Displays the current setting of the #VRN command as an ASCII decimal value in
Result Code format.
VRN=?
Returns the message, “0-255”.
VRN=0
Turns off the “ringback never came timer.” After dialing, the modem sends VCON and
immediately enters Online Voice Command Mode.
VRN=n
Where
n
defines the period without ringback after dialing in 100 ms units.
-SDR Distinctive Ring
(Requires Feature #156.) Bits set high in this register enable the corresponding Distinctive
Ring detection and Result Code. Bits disabled set normal ring detection only. Range = Ø-7,
Default=Ø. (Saved in NVRAM via &W).
NOTE—
Current code does not discriminate between short (0.4 second) and long (0.8
second) ring pulses. Two Bellcore standard ring patterns (RINGS 3 and 4) will be reported as
RING3 (If RING 3 detection is active).
