| Description | This is an object for an E & M signaling protocol like
wink-start for this ds0. The difference is that the
address-control signal is different from wink. The originating
VISM, on receiving a seize (AB=11) from the PBX,
responds by sending the delay-dial (AB=11) signal back
to the PBX. When the originating VISM is ready to collect
the digits, it sends a start-dial (AB=00) signal.
This operation is symmetric. So the terminating VISM, on
seizing a trunk, should receive AB=11
(as an ack that the trunk is operational). Subsequently,
when it receives the start signal (AB=00) from
the connected PBX, it should outpulse the digits.
The rest of the operation is similiar to wink-start.
The allowed range for this object is 70..1000.
In delay-dial operation, the outgoing interface (this interface),
after receiving a delay-dial signal (AB=11) from the connected
equipment, waits for the start-dial signal (AB = 00) before
sending the digits to the connected equipment.
The start-dial signal tells this interface that the
connected equipment is ready for the digits.
This object specifies the time in milliseconds, after which
incoming AB=00 will be interpreted by this interface as the
start dial signal. |
