 NT8D14 Universal Trunk card

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 Figure 128 on 

. 

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 System 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 129 on 

 also applies to incoming 

calls on a DID trunk from a CO.

 

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 130 on
