Page 502Primary Rate Interface (PRI) and T1
■ Signaling mode (for T1 service only)
NOTES:
1. Most of these settings are dependent upon the central office and the
type of service (T1 or PRI) to which you subscribe.
2. In Release 6.0 and later systems (Hybrid/PBX mode only), tandem PRI
and tandem T1-emulated tie trunks are set up using type of service,
framing format, line coding, line compensation, and clock
synchronization options; they can use the same settings as other PRI
and T1 tie trunks. For details, see
System Programming .
Type of Service 31
The system supports two types of service for DS1 facilities: T1 and PRI. The 100D
module can be programmed to operate in either type of service. T1 service
transmits and receives voice and analog data, as well as digital data in Release
4.0 and later communications systems; PRI transmits and receives voice, analog,
and digital data. Any combination of the following AT&T Switched Network (ASN)
Services can be provided through a T1 or a PRI line/trunk:
■ Megacom WATS service for domestic outgoing long-distance voice calls
■ Megacom 800 service for domestic toll-free incoming voice calls
■ Software-Defined Network (SDN) for voice and circuit-switched data calls
■ MultiQuest
®
for 900 service numbers
PRI interacts with the ACCUNET Switched Digital Service for 56-kbps, 64-kbps
restricted, and 64-kbps clear circuit-switched data calls. T1 supports ACCUNET
Switched Digital Service or other circuit-switched data service at 56 kbps in
Release 4.0 and later.
T1 and PRI support Shared Access for Switched Services (SASS), which allows
both Megacom and Megacom 800 services to be offered over the same line. This
eliminates the need to have separate incoming and outgoing lines/trunks when
these services are chosen.
In Release 4.2 and later systems, when PRI is selected as the type of service, any
combination of the following MCI and local exchange carrier services are
supported, in addition to the AT&T services supported in prior releases:
■ MCI services include:
— MCI PRISM. For domestic outgoing long-distance and international
voice calls; domestic outgoing 56-kbps restricted as well as 64-kbps
restricted or unrestricted circuit-switched data calls.
— MCI 800. For domestic toll-free incoming voice calls.
— MCI Vnet. For domestic incoming and outgoing voice calls; or for
outgoing 56-kbps restricted as well as 64-kbps restricted or unrestricted
circuit-switched data calls.
