Multiple Subscriber Number (MSN) - Limited
The ISDN standard MSN feature lets customers assign multiple extension to a
single BRI endpoint. The MSN feature works with BRI endpoints that allow the
Channel ID IE to be encoded as “preferred.”
Call-by-Call Service Selection
Enables a single ISDN-PRI trunk group to carry calls to a variety of services,
rather than requiring each trunk group to be dedicated to a specific service. It
allows you to set up various voice and data services and features for a particular
call.
CAMA - E911 Trunk Group
This form administers the Centralized Automatic Message Accounting (CAMA)
trunks and provides Caller’s Emergency Service Identification (CESID) informa-
tion to the local community’s Enhanced 911 system through the local Central
Office.
Facility and Non-Facility Associated Signaling
Allows an ISDN-PRI DS1/E1 interface D-channel to carry signaling information for
B-channels (voice or data). D-Channel Backup can also be administered to
increase system reliability.
Wideband Switching
Provides the ability to dedicate 2 or more ISDN B-channels or DSO endpoints for
applications that require large bandwidth. Certain applications, such as video
conferencing and high-speed data transmission, require extra bandwidth and it
becomes necessary to put several ISDN-PRI narrowband channels into one
wideband channel to accommodate the needs of these applications. This feature
supports both European and North American standards.
