Connecting the Router
Connecting a Voice ISDN BRI Line
Use a straight-through RJ-45 cable to connect the Voice Basic Rate Interface (BRI) port to the ISDN
network through a telephone wall outlet or other device.
Caution
To prevent damage to the router, be sure to connect the BRI cable to the BRI connector only, and not to
any other RJ-45 connector.
To connect the Voice BRI line, follow these steps:
Connect one end of a straight-through RJ-45–to–RJ-45 cable to the Voice BRI port.
