BRI (Basic Rate Interface) ISDN Telephony Interface Module

XR0037

BRI (Basic Rate Interface) ISDN is a digital telephony interface (P/N XR0037) used to connect to the telephony provider, legacy PBX or ISDN telephone sets. There are two basic configurations for each BRI ISDN telephony interface 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).

    • Available in combined units with analog ports (see the “Astribank Telephony Interfaces Configurations” section on the Astribank page)

IP-PBX Integration

  • Each BRI ISDN telephony interface 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).
