5.2.1

Connecting BRI Lines

The BRI ports can be connected to ISDN terminal equipment such as ISDN telephones or
PBXs. Each BRI port can be configured either as termination equipment/user side (TE) or
network termination/network side (NT). Up to eight terminal equipment (TE) devices can be
connected per BRI S/T port, using an ISDN S-bus providing eight ISDN ports. When
configured as NT, the BRI port drives a nominal voltage of 38V with limited current supply
of up to 100 mA.
Warning:
the BRI ports to the PSTN.
Note: BRI interface is a customer-ordered item which is supported only on specific
hardware configurations. For more information, contact your AudioCodes sales
representative.
