Trunk Group
Issue 5 October 2002 1265555-233-506
NOTE:
The value in this field affects the appearance of the Incoming Partial Dial
(sec) field on the Administrable Timer Page.
Version
Use this field to adjust the signaling on multi-country CO trunk circuit packs.
Entries in this field adjust signaling characteristics on these circuit packs to match
the signaling characteristics of the public network in a specific country. The field
appears only for CO, FX, and WATS trunk groups when the Country field is
5, 16,
or
23.
Wink Timer (msec)
This field allows you to reduce the risk of glare by controlling part of call setup.
Requirements for the United States domestic network specify that the wink signal
for wink-start trunks must begin within 5 seconds after a trunk is seized. For
trunks with a delay-dial start, the wink must not last longer than 5 seconds. While
some circuit packs are hard-coded to allow the full 5 seconds in both cases, other
circuit packs allow you reduce the allowed start time and duration, thus reducing
the window in which glare could occur.
Unlike other fields on this screen, the Wink Timer field therefore controls 2
different variables. What your entry does depends on the outgoing value in the
Trunk Type (in/out) field.
Valid entries Usage
If the Country field is 5, the Version field only controls TN2147 ports.
a Enter a to use standard signaling for the Netherlands public
network.
b
Enter b to use country 1 (U.S.) signaling. The value b is
appropriate if your switch is connected to a central office
using an Ericcson AXE-10 switch.
If the Country field is
16 or 23, the Version field sets the input impedance
value and only controls TN465C (vintage 2 or later) ports.
a Enter a to set input impedance to 600 Ohms.
b
Enter b to set input impedance to 900 Ohms. The value b is
appropriate in Brazil.
