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.
