BRI (Basic Rate Interface) ISDN is a digital telephony interface used to connect to the telephony provider, legacy PBX or ISDN telephone sets.
There are two basic configurations for each BRI port - TE (Terminal) - connects to telephony provider and NT (Network) - connects to ISDN phones (requires power supply option) or legacy PBX (as PSTN ISDN trunks).
BRI ISDN Models
The Xorcom BRI module supports two configurations:
- 2 ports (dual BRI) supporting 4 channels
- 4 ports (quad BRI) supporting 8 channels
- 4 ports (quad-port BRI) supporting 16 channels
Each set of ports can be licensed separately (and remotely) allowing field upgrade.
Each module has dip-switches to set each port to either NT or TE mode. Power for ISDN phones is supplied by the module. Status LEDs for each port indicate active settings (TE or NT) and line status (no activity, layer 1 active, layer 2 active).
The BRI module is available in both the Astribank full size (1U) chassis as well as in the compact 10" units.
One BRI module (with up to eight BRI ports) may be installed in a single Astribank or Xorcom IP-PBX unit. Use the on-line Product Configurator wizard to determine the most suitable configuration to fit your needs.
