Reference Guide for the Model RT328 and Model RH348 ISDN Routers
Warning: Several of the connectors and connection cables are very similar. It is important that you use the correct cable for each connection and that you do not connect the ports incorrectly, because serious damage to your router could result.
Connecting the Serial Cable (Optional)
Plug one end of the 9-pin RS-232 cable into the MGR (manager) port on the router. Plug the other end into a serial port (such as COM1 or COM2) of your PC. You must use the included 9-pin to 25-pin adapter if your PC has only a 25-pin port available.
Connecting to the ISDN Port
In regions where the S interface version of the router is used, the ISDN cable will have two 8-pin RJ-45 connectors. Plug one end of the cable into the ISDN port of the router and connect the other end to an NT1 (Network Termination) device, a DSU device, or an S-interface wall jack.
In regions where the U interface version of the router is used, your ISDN cable will have an 8-pin RJ-45 connector on one end and either an 8-pin RJ-45 (earlier versions) or a 6-pin RJ-11 (later versions) connector on the other end. Plug one 8-pin connector into the ISDN port of the router. Connect the other end of the cable directly to your ISDN wall jack. Your wall jack may have either an 8-pin RJ-45 or a 6-pin RJ-11 connector. A 6-pin cable connector will plug into the center of an
8-pin wall jack, but if you have a 6-pin jack and an 8-pin cable connector, you must either change the jack or get a cable with two 6-pin connectors.
Connecting the Ethernet Cable
The Model RT328 router supports two types of Ethernet connections. Follow the procedure that is appropriate for your installation.
