NOTES:
1. You cannot mix T1 and Primary Rate Interface (PRI) service on the same
100D module. Any of the following AT&T Switched Network (ASN)
Services can be provided through a T1 or PRI facility: Megacom
WATS,
Megacom 800, Software Defined Network (SDN), and MultiQuest
. PRI
also supports Call-by-Call Service Selection and some ACCUNET
switched digital services. T1 supports Shared Access for Switched
Services (SASS) and ACCUNET Switched Digital Service (or other
circuit-switched data service) at 56-kbps. Both support Dialed Number
Identification Service (DNIS).
2. The MERLIN LEGEND Communications System supports Centrex
service with loop-start lines only. The system does
not
support a timed
switchhook flash with ground-start trunks or ground-start emulation on
DS1 facilities in any mode of operation (Hybrid/PBX, Key, or Behind
Switch).
