ISDN BRI Interfaces
This section describes how to cable the BRI interfaces.
Connecting to BRI Lines
The device provides up to four BRI S/T ports. These ports connect to ISDN terminal equipment
such as ISDN telephones. 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 that provides eight ISDN ports. When
configured as NT, the BRI port drives a nominal voltage of 38 V with limited current supply of up to
100 mA.
● BRI port cabling must be routed only indoors and must not exit the building.
● To protect against electrical shock and fire, use a 26 AWG min wire to connect the
BRI ports to the PSTN.
BRI interfaces are a separate orderable item.
Cable specifications:
■ Cable: 26 AWG min.
■ Connector Type: RJ-45
■ Connector Pinouts:
