Description This module eliminates the need for an external ISDN terminal adapter. The ASN supports two ISDN BRI/DUAL synchronous net modules and up to three quad ISDN BRI net modules. It provides two 64-Kbps B-channels for data and one 16-Kbps D-channel for signaling. The rate adaption for 56- and 64-Kbps transmission rates on B-Channels is also supported each BRI port can be multidropped on the same link with other ISDN devices.
