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.

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 Trunk Administration program LD 14. See
196 "Two-way, loop DR, tie trunk call states - incoming call through a
senderized, tandem PBX from a CO" (page
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,

also applies to incoming calls on a DID trunk from a CO.
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.
