ISDN U Cable
For pinout details of the ISDN cables, see Appendix A.
To connect the ISDN BRI port:
1
Turn off power to the router.
Caution:
Identify the router model and the ISDN BRI mark on the port when
making the connection. Plugging the connector in incorrectly can cause damage
to the router
2
Confirm the type of ISDN line provided by the telecommunications service
provider.
3
Connect the cable.
For the Router 3013:
a
If the line is ISDN U, use an NT1 adapter . Insert one end of the S/T cable into
the S/T port of the NT1, and the other end into the ISDN BRI port of the router.
b
If the line is ISDN S/T, insert the cable directly into the ISDN BRI port of the
router
For the Router 3015:
a
If the line is ISDN S/T, replace your router with a Router 3013.
b
If the line is ISDN U interface cable, connect the RJ-45 connector to the ISDN
BRI interface of the router, and connect the output terminal (OT) end to the
ISDN line through a telephone adapter.

During the installation of the router, you must verify whether the router has been
correctly installed by checking the following items:
■
There is enough heat-dissipation clearance around the router, and whether the
workbench is stable enough
■
Power is connected correctly
■
The ground wire of the router is correctly connected
■
The router is connected to other devices, such as the console terminal
