Trunk Type
Use this field to control the seizure and start-dial signaling used on this trunk group. Entries in this field
vary according to the function of the trunk group and must match the corresponding setting on the far-end
server or switch. This field appears for CO, DID, FX, and WATS trunk groups.
See Transmission and supervisory signaling on page 1743 for more information. Procedures in Tips for
Working with Trunk Groups on page 349 give specific suggestions for signaling to use with different
types of trunk groups.
Valid entries Usage
ground-start Use ground-start signaling for two-way trunks whenever possible:
ground-start signaling avoids glare and provides answer
supervision from the far end.
loop-start In general, try to use loop-start signaling only for one-way trunks.
Loop-start signaling is susceptible to glare and does not provide
answer supervision.
auto/auto The term before the slash tells Communication Manager how and
when it will receive incoming digits. The term after the slash tells
Communication Manager how and when it should send outgoing
digits.
•
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.
•
delay — The sending server running Communication
Manager 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 server or switch, indicating that it’s ready
to receive the digits.
•
wink — The sending server running Communication
Manager 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 running Communication
Manager sends digits without waiting for a signal from the
far-end server or switch.
