Preface
The ISDN BRI Adapter Module provides connectivity for using Nortel
Networks™ dial services such as Dial Backup, Dial-on-Demand and
Bandwidth-on-Demand. The BRI provides two B channels, and supports full
D-channel signaling and call setup/teardown as defined in 1988 CCITT (now
ITU-T) Recommendation Q.921 and Q.931.
