Connecting the Router to the Ethernet
For thick and thin Ethernet networks you should have installed your Ethernet
cabling before you install the BR Router.
If you have a coax installation, the Ethernet network cable should be terminated at
both ends with 50 Ohm network terminating resistors, and a T-connector or
transceiver should be available at the location where you will connect the router.
If you are installing a twisted-pair connection, and the twisted-pair hub is already in
place, or a T-connector or thicknet transceiver is already installed on your Ethernet
cable, you can connect the router to an active network without interrupting network
activity.
The BR Router’s Ethernet interface features all three media connector types. The
active media connection will automatically be selected when you attach a cable.
Do not terminate inactive connectors on the router, as this may cause an
incorrect media type to be selected.
Connecting to Thick Ethernet
To connect the router to a thick Ethernet network, simply plug one end of a
transceiver cable into the DB-15 transceiver connector located on the back panel of
the unit. Then, plug the other end of the transceiver cable into the transceiver
which should already be attached to the thick Ethernet cable.
Connecting to Thin Ethernet
In order to connect the router to a thin Ethernet cable, connect a T-connector to the
BNC connector located on the rear panel of the unit.
Connecting to Twisted-Pair Ethernet
Before connecting the router to twisted-pair cabling you need an unshielded twisted-
pair cable that is already connected to your 10BaseT-compatible twisted-pair hub.
To connect the router to the twisted-pair network, simply plug the twisted-pair cable
into the RJ-45 connector on the back of the unit.
Connecting a Line Device to the BR Router
The BR Router supports high-speed synchronous or asynchronous operation over
one RS-232 connector.
The BR Router supports both PPP and Frame Relay link protocols on this WAN
port.
Connecting Devices to the RS-232C Port
This port -- marked WAN -- can be used to connect to synchronous or asynchronous
line communications devices at rates up to 128Kbps (115.2 Kbps async).
