Chapter 3 - Network Installation
Connecting the Router to the Ethernet
If your twisted-pair hub is already in place, you can connect the router
to an active network without interrupting network activity. The router
must be powered off.
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 Ethernet connector on the back of the
unit.
Connecting a Line Device to the
MicroRouter 1220i
The MicroRouter 1220i supports high-speed synchronous operation
over a V.35 connector. It also supports lower speed synchronous/asyn-
chronous operation over an RS-232 connector.
The MicroRouter 1220i independently supports PPP, Frame Relay and
SMDS link protocols on WAN 0 and PPP and Frame Relay on WAN 1.
Connecting Devices to the V.35 Interface
This interface -- WAN 0 -- can be used to connect to a wide variety of
line communications devices, including those which support either
leased or dialed operation. Examples include leased 56K CSU/DSUs,
switched 56K CSU/DSUs, fractional T1 CSU/DSUs, ISDN terminal
adapters, and full T1/E1 rate CSU/DSUs.
You may select either dial-on-demand, redial if down (“always up”
mode), or leased line operation. This interface may also be set to
receive ISDN or switched 56 incoming calls.
To connect a device, first make sure that both units are powered off.
Then, simply connect a V.35 cable (not supplied) between the router
and the device.
