Senderized operation for DID and two-way loop DR trunks

Incoming calls
If the far-end is senderized, the near-end can be operated 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
Figure 25 on page 72.
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 Succession CSE 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
Trunk Route Administration program LD 16.
The operation represented in Figure 25 also applies to incoming calls on a
DID trunk from a CO.
Outgoing calls
When DDL or WNK mode is used, outgoing calls require a stop/go signal
from the far-end so that the near-end cannot outpulse until the far-end is ready
to receive digits. See Figure 26 on page 73.
Note: Pseudo-answer supervision is provided by near-end at expiration
of end-of-dial timer. Where no far-end answer supervision is provided,
party at far-end hangs up after recognizing near-end call termination.
