NOTE:
In Release 6.0 and later systems, you may order a point-to-point T1 circuit
in order to provide amplification but not switching for a PRI tandem trunk
that carries calls over long distances. PRI tandem trunks are preferable to
T1 tandem trunks. Consult your Lucent Technologies representative for
advice.

If the type is T1 and the type of channel emulation is tie trunk, you must specify
whether the lines/trunks are TIE-PBX, Toll, or Switched 56 Data service. The valid
settings are as follows:

settings are as follows:
■
TIE-PBX. Select when emulated tie trunks are used to connect to another
communications system (such as PBX or Centrex). For releases prior to
Release 6.0, the transmit/receive parameter is set to 0/4.

■
Toll. Select when emulated tie trunks are used for ASN services (such as
Megacom‚ Megacom 800, or Software Defined Network). For releases
prior to Release 6.0, the transmit/receive parameter is set to 0/6.

NOTE:
The parameters listed in the two above items are for releases prior to
Release 6.0. In Release 6.0 and later systems, the transmit/receive
gains are determined by the call constituents.

If the type is T1 and S56 Data Network Service is selected (available only in
Release 4.0 and later), you must specify the following parameters:

Direction. Specifies whether the trunk operates in one- or two-way
direction. For one-way trunks, Outgoing Only or Incoming Only must also
be specified.

Trunk Seizure Type. Trunk seizure type is programmed independently for
incoming or outgoing directions. Select one of the following: Wink Start,
Delay Start, or Automatic Start.
