Notes:
• The lifeline splitter cable is a separate orderable item.
• Analog Lifeline cabling is applicable only if the device is ordered with FXS interfaces.
• The number of supported Lifelines depends on the device’s hardware configuration.
For the combined FXS/FXO configuration, one Lifeline is available; for the 12-FXS
configuration, up to three Lifelines are available.
5.5 ISDN BRI Interfaces
5.5.1 Connecting to BRI Lines
The device provides up to eight 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.
