Connecting a Data BRI Port

You can connect the Data BRI port to the ISDN service provider as a backup link to the WAN port in
case the primary xDSL (general term referring to various forms of DSL, including global industry

The cabling requirements for the ISDN S/T connection are as follows:
•
•
Caution Both LAN and WAN ports use RJ-45 connectors. Use caution when connecting cables to these
connectors. To avoid damage to the router, do not connect telephone-network voltage (TNV) circuits
(such as ISDN or DSL circuits) to safety extra-low voltage (SELV) circuits (such as LAN circuits).

RJ-45–to–RJ-11 ISDN S/T cable is available upon request if the wall jack at the site requires an
RJ-11 connector. Contact your router reseller for the appropriate cable.
