Screen Reference
Trunk Group
Trunk Type (in/out)
Use this field to control the seizure and start-dial signaling used on this trunk group. The setting of the
Trunk Signaling Type field can affect the entries allowed in this field. In addition, settings may differ for
incoming and outgoing trunks.
Valid entries
auto
cont
delay
disc
immed
wink
2-wire-ac
2-wire-dc
3-wire
Tip:
When incoming trunks use the setting immed/immed, the far-end media server or switch
seizes the trunk and sends digits without waiting for acknowledgment from the receiving
end. When traffic is heavy, the receiving server or switch may not immediately attach a
Touch Tone Receiver to a call and therefore lose digits. Use wink-start trunks or increase
the dial-guard timer value on the far-end server or switch to avoid this problem.
NOTE:
The value in this field affects the appearance of the Incoming Partial Dial (sec) field on the
Administrable Timer Page.

Usage
There are numerous valid entries for this field: use the online help in
Communication Manager 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
server/switch seizes a trunk by sending a continuous seizure signal for at
least the duration specified by the Incoming Seizure Timer. See
on page 1285 for more information.
•
delay — The sending switch does not send digits until it receives a delay
dial signal (an off-hook signal followed by 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 media server or 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 end can
also send routing information to the called end by sending one or a series of
brief seizure signals.
•
wink — The sending server or switch does not send digits until it receives a
a wink start (momentary off-hook) signal from the far-end server or switch,
indicating that it's ready to receive the digits.
•
immed — The sending server or switch sends digits without waiting for a
signal from the far-end server or switch.
These entries are used with CO trunks in Russia: enter the type of connection to
your central office. Check with you network service provider if you don't know
what type of connection they're using. To use these entries, the Country field must
be 15 and the CO trunks must use ports on a TN2199 circuit board.
