Trunk Signaling Type
This field controls the signaling used by members in private network trunk groups,
mainly in Italy, Brazil, and Hungary. This field appears if the Group Type is
access, aplt, diod, rlt, tandem, or tie. Entries in this field affect which timers
appear on the Administrable Timers page.
Valid entries Usage
cont
(continuous)
E&M trunks in Italy, Brazil, and Hungary can use either
continuous or discontinuous signaling. Each entry specifies a
set of signals and available timers used in the process of setting
up and releasing connections. The type of signaling you select
on your switch must match the signaling type administered on
the far-end switch. Use these values only when all trunk group
members are assigned to ports on a TN464F, TN2464, or
TN2140 circuit pack. Entering one of these values causes the
Send Release Ack, Receive Release Ack, and Send Answer
Supervision fields to appear. Refer to ‘‘
Trunk Type (in/out)’’
on page 984 for more information.
dis
(discontinuous)
blank If this field is blank, ports from any other tie trunk circuit pack
may be added as trunk group members.
Use the following entries for tie trunks in Main-Satellite/Tributary networks. Each
entry defines a function of the trunk group in the network. Use these values only
when all trunk group members are assigned to a TN497 circuit pack.
tgu
(for outgoing
trunks)
Enter
tgu at the main switch to administer a tie trunk group
connected to a satellite switch. (This same group should be
administered as
tge at the satellite.)
tge
(for incoming
trunks)
Enter
tge at a satellite switch to administer a tie trunk group
connected to the main switch. (This same group should be
administered as
tgu at the main switch.)
tgi
(for internal
trunks)
Enter
tgi at to administer a two-way tie trunk group between 2
satellites or between the main switch and a satellite. (This trunk
group should be administered as
tgi on both switches.)
