The procedure below describes how to connect to BRI lines.
Warning:
Note:
To connect to BRI lines:
1. Connect the BRI cable to the device's BRI RJ-45 port.
2. Connect the other end of the cable to your ISDN telephone or PBX/PSTN switch.
A BRI port can be configured either as TE (Termination Equipment/user side) or NT
(Network Termination/network side). The connector pinouts vary according to the
configuration, as shown below:
When configured as NT, the BRI port drives a nominal voltage of 38 V with limited current
supply of up to 100 mA. The voltage is of Power Source 1 type (line voltage). Power Source
2 is optional.
Hardware Installation Manual
To protect against electrical shock and fire, use a 26 AWG min wire to
connect the BRI ports to the PSTN.
The BRI module is a customer ordered item. This section is applicable only if
your device is installed with such a module.
