For delay dial or wink start modes, stop/go signaling (off hook/on hook or

battery/ground reversal) is returned by the Meridian 1 after receipt of the

seizure signal. The delay dial (stop) signal begins immediately upon seizure

and ends (go signal) 384 ms later. The wink start (stop) signal begins 384

ms after seizure and ends (go signal) 256 ms later. The far-end detecting

the go signal may start pulsing after the standard delay (normally 55 ms,

minimum). Stop/go signaling, in addition to the signaling function, serves as

an integrity check to help identify a malfunctioning trunk.

If required, the near-end can be conﬁgured to provide pseudo-answer

supervision at expiration of the end-of-dial timer. End-of-dial timer settings

are made at the EOD (non-DTMF) or ODT (DTMF) prompts in the Trunk

Route Administration program LD 16.

The operation represented in Figure 194 "Two-way, loop DR, TIE trunk call

states - incoming call through senderized, tandem PBX from a CO/FX/"

(page 645) also applies to incoming calls on a DID trunk from a CO.

If the far-end is senderized, the near-end can operate in any mode:

Immediate Start (IMM), Delay Dial (DDL) or Wink (WNK) start, as assigned

at the STRI prompt in the TrunkAdministration program LD 14. See Figure

196 "Two-way, loop DR, tie trunk call states - incoming call through a

senderized, tandem PBX from a CO" (page 647).

Note: If a ground start trunk, the outpulse towards ofﬁce occurs after

ground detection. If a loop start trunk, the outpulse towards ofﬁce

occurs one second later.

For immediate start, following the seizure signal,the far-end starts pulsing

after the standard delay (normally 65 ms, minimum).

For delay dial or wink start modes, stop/go signaling (off hook/on hook or

battery/ground reversal) is returned by the CS 1000 after receipt of the

seizure signal. The delay dial (stop) signal begins immediately upon seizure

and ends (go signal) 384 ms later. The wink start (stop) signal begins 384

ms after seizure and ends (go signal) 256 ms later. The far-end detecting

the go signal starts pulsing after the standard delay (normally 55 ms,

minimum). Stop/go signaling, in addition to the signaling function, serves as

an integrity check to help identify a malfunctioning trunk.

If required, the near-end can be conﬁgured to provide pseudo-answer

supervision at the expiration of the end-of-dial timer. End-of-dial timer

settings are made at the EOD (non-DTMF) or ODT (DTMF) prompts in the

TrunkRoute Administration program LD 16.
