Connecting a Voice ISDN BRI Line Chapter 3 Connecting the Router Note If you have specified the use of a private line automatic ringdown (PLAR) off-premises extension (OPX) connection mode for an FXO voice port (with loop resistance less than 8000 Ohm), you must ensure that the soft-offhook option is enabled on the port. This option allows a stepped offhook resistance during seizure which avoids overloading the circuit during offhook in the event that ringing voltage is present on the circuit at the same time as the trunk seizure. The stepped offhook resistance is initially set to 800 Ohms, then adjusts to 50 Ohms when ringing voltage is not present. To enable soft-offhook command on the port, and to access the connection command with plar opx syntax, see the Cisco Command Lookup Tool. Connecting a Voice ISDN BRI Line Use a straight-through RJ-45 cable to connect the voice BRI port to the ISDN network through a telephone 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: Step 1 Connect one end of a straight-through RJ-45-to-RJ-45 cable to the Voice BRI port. Note When the interface is configured as NT and is connecting to a TE device, use a crossover cable.

Connecting the Router

Connecting a Voice ISDN BRI Line

Note

If you have specified the use of a private line automatic ringdown (PLAR) off-premises extension (OPX)

connection mode for an

FXO voice port (with loop resistance less than 8000 Ohm), you must ensure

that the soft-offhook option is enabled on the port.

This option allows a stepped offhook resistance during seizure which avoids overloading the circuit

during offhook in the event that ringing voltage is present on the circuit at the same time as the trunk

seizure. The stepped offhook resistance is initially set to 800 Ohms, then adjusts to 50 Ohms when

ringing voltage is not present.

To enable

soft-offhook

command on the port, and to access the

connection

command with plar opx

syntax, see the

Cisco Command Lookup Tool

Connecting a Voice ISDN BRI Line

Use a straight-through RJ-45 cable to connect the voice BRI port to the ISDN network through a

telephone 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:

Step 1

Connect one end of a straight-through RJ-45–to–RJ-45 cable to the Voice BRI port.

Note

When the interface is configured as NT and is connecting to a TE device, use a crossover cable.
