BRI Service on the AN, ANH, and ASN
The Access Node (AN), Access Node Hub (ANH™), and Access Stack Node
(ASN) support the BRI standard for ISDN using an integrated ISDN/BRI module.
The integral ISDN BRI functionality allows you to connect directly to the ISDN
network, as opposed to connecting via a terminal adapter. With BRI support, you
reduce equipment costs and simplify connections to an ISDN switch.
The BRI implementation supports all three dial services. In addition, the
implementation supports an ISDN leased-line application (only for Germany).
Later chapters in this book describe how to configure each service for connection
to an ISDN network.
B Channel Support
In keeping with the BRI standard, each port on the ISDN/BRI module provides
two 64 Kb/s B channels for data transmission, allowing communication with two
remote locations simultaneously.
D Channel Support
The router supports full 16 Kb/s D channel signaling and call setup and tear down
between the router and ISDN switch. The D channel implementation complies
with ITU-T (formerly CCITT) 1988 recommendations Q.921 and Q.931, with
signaling support for the following countries:
• INS-64, KDD, and NTT for Japan
• TS013 for Australia
• National ISDN 1, AT&T 5ESS Custom, and NT DMS-100 Custom for the
United States, Canada
• Swissnet 3 for Switzerland
• NET3 for: Austria, Belgium, Denmark, France, Germany, Italy, Netherlands,
Norway, Spain, Sweden, Switzerland, United Kingdom
Bay Networks implementation does not allow you to send data across the D
channel.
