ISDN BRI Card
Overview
Overview
The ISDN BRI Service Cards enable service providers and enterprises to deploy high-
density, standards-based, ISDN Basic Rate Interface (BRI) services over one or more
T1 or DSL access lines using TDM or ATM transport. ISDN voice, data, and real-time
video applications may be cost effectively deployed as part of any integrated
broadband service delivery.
ISDN BRI
BRI provides an end-to-end digital connection for customers with voice, data and video
needs. BRI has 2 Bearer (B) channels at 64 Kbps for voice or data and 1 Data or Delta
(D) channel at 16 Kbps for signal and control. With some ISDN BRI devices, the two
B-channels can be aggregated together for 128 Kbps capacity.
3-DS0 BRITE Mode
The ISDN BRI Card supports the 3-DS0 BRITE mode of operation. In this mode, three
DS0 channels support a BRI channel, providing eight BRI per T1. The BRI channel
consists of two B and a D channel (2B+D) which is also transported in a full DS0. The
D-channel supports the Embedded Operations Channel (EOC) and is used to pass
signaling and other management information, such as loopback commands.
The following is an example of how a Axxius 800 with a ISDN BRI card can function
as a Line Unit Network Termination (LUNT) with central office applications, and a
Line Unit Line Termination (LULT) with subscriber lines.
