DID Control
Description:
Decide upon which address supervision signalling protocol that you will use. This decision will
depend upon the type of supervision that is compatible with the CO requirements.
Immediate
Start:
this protocol for rotary (pulse dial) lines. With this protocol, the CO will
not expect address supervision signalling and may begin pulsing the dialing digits as soon as 65
msec. after it connects to the line.
Wink
Start: With this protocol, the CO will expect address supervision signalling. After the
CO connects to the line, the
Plus will reverse the polarity of the line for a period of 200
when it is ready to receive digits (that is, the DTMF receiver is available for tone dial
lines). This “wink” signal indicates to the CO that the DXP
is ready to receive incoming
digits. After the wink occurs and the line polarity returns to normal, the CO will begin sending
the dialing digits. If the CO does not see the wink within 4 to 8 seconds (heavy traffic timings),
it may route the call to network reorder or retry the call on another line.
Typically, a CO will
try to dial two times. A second failure will result in network reorder. Wink start protocol is the
best choice for its combination of integrity checks and retrial capabilities.
Delay Start:
With this protocol, the CO will expect address supervision signalling.
Approximately
msec. after the CO connects to the line, the DXP Plus will reverse the
polarity of the line for a period of at least 140 msec. It will hold this reversal until it is ready to
receive incoming digits. At that time, it will return the polarity to normal. After the line
polarity returns to normal, the CO will begin sending the dialing digits. If the CO does not see
the line polarity return to normal within 4 to 8 seconds, it will route the call to network reorder.
There is no requirement for the CO to retry failures on lines with delay dial signalling.
