There are numerous valid entries for this field: use the online
help in the switch administration software to view all the
possible combinations. Here are what the elements used in
those combinations mean:
■auto — Used for immediate connection to a single preset
destination (incoming CO trunks, for example). No digits
are sent, because all calls terminate at the same place.
■cont — Continuous signaling is used with Italian E&M tie
trunks. The switch seizes a trunk by sending a continuous
seizure signal for at least the duration specified by the
Incoming Seizure Timer. Refer to ‘‘Trunk Signaling Type’’
on page 974 for more information.
■delay — The sending switch does not send digits until it
receives a delay dial signal (an off-hook signal foll o wed b y
an on-hook signal) from the far-end switch, indicating that
it’s ready to receive the digits.
■disc —Discontinuous signaling is used with Italian tie
trunks that use E&M signaling. The switch can seize a
trunk by sending a single, short signal for the duration
specified by the Normal Outgoing Seize Send field.
However, with the Three-Way Seizure option the calling
switch can also send routing information to the called
switch by sending one or a series of brief seizure signals.
■wink — The sending switch does not send digits until it
receives a a wink start (momentary off-hook) signal from
the far-end switch, indicating that it’s ready to receive the
digits.
■immed — The sending switch sends digits without waiting
for a signal from the far-end switch.
