Make the Link Connection(s)
By default the links are configured as permanent DTE interfaces. The clocking for each link
will be provided by the DCE device connected to each link.
The V.35 link modules require interface converters that convert from a DB25 connector to
a male 34-pin (V.35) connector used for the V.35 interface. Be sure to secure the cable
connector(s) to the bridge/router and the communications equipment with the connector
screws to prevent accidental disconnection.
The CSU/DSU module uses a RJ-48S connector to interface with the digital data service.
G.703 modules use a standard BNC connector with a 75 ohm cable.
The ISDN-ST interface module of the ISDN Router provides a RJ-45 connector to connect
to the RJ-45 connector of the NT1 provided with your ISDN service.
The ISDN-U interface module of the ISDN Router provides an integrated NT1 with a RJ-
45 connector to connect directly with your ISDN service.
Pinouts for the WAN connectors are listed in Appendix D of this manual.
