Type Of Ds1 Facility - AT&T MERLIN LEGEND Release 3.0 Programming Summary Manual

Type of DS1 Facility

Type of DS1 Facility
Use this procedure to specify the type of facility (T1 or PRI) connected to a
100D (DS1) module. If T1 type is programmed, and the channels are used for
emulation and/or AT&T Switched Network (ASN), you must specify the type of
channel emulation. If the type is T1 and the type of channel emulation is tie
trunk, you must specify the transmit/receive loss parameter settings are also
selected. The two valid settings are as follows:
TIE-PBX. Select when emulated tie trunks are used to connect to
another communications system (such as PBX or Centrex). 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). The
transmit/receive parameter is set to 0/6.
If you select T1, channels can emulate ground-or loop-start trunks, tie trunks,
or DID trunks in any combination. Note that unused channels must be
specified as unequipped.
If either T1 or PRI is selected, channels can be used for ASN services. When
T1 channels are used for ASN services, each channel must be programmed
for tie trunk emulation.
If you select PRI, you must also perform additional procedures. At a minimum,
the Framing Mode and Zero Code Suppression procedures must be
performed. See "PRI Facilities" for more information.
