DS1 Facilities 4
Use the procedures in this section to program the following options for DS1
(digital signal level 1) facilities (T1 or PRI) connected to a 100D (DS1) module:
■ Type of DS1 facility
—T1
— ISDN (Integrated Services Digital Network) Primary Rate Interface
(PRI)
■ Switched 56 Dial Plan Routing
■ Frame Format
■ Zero Code Suppression
■ Signaling Mode
■ Line Compensation
■ Channel Service Unit
Type of DS1 Facility 4
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.
NOTE:NOTE: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.
