For example, the customer site is assigned the addresses

192.168.1.0/24 through 192.168.1.1/24. The address
192.168.1.1/24 is also the default gateway for the remote
network. The above settings remove any routing/forwarding
intelligence from the CPE. The associated Cisco configuration
will set serial interface (s0) to accommodate half bridging for
the above example.

Authentication is optional under PPP. In a point-to-point

leased-line link, incoming customer facilities are usually fixed
in nature, therefore authentication is generally not required. If
the foreign device requires authentication via PAP or CHAP,
the PPP software will respond with default Peer-ID consisting
of the units Ethernet MAC address and a password which
consists of the unit’s Ethernet MAC address.

Some networking systems do not define network numbers

in packets sent out over a network. If a packet does not have
a specific destination network number, a router will assume
that the packet is set up for the local segment and will not
forward it to any other sub-network. However, in cases where
two devices need to communicate over the wide-area,
bridging can be used to transport non-routable protocols.

Figure 3 illustrates transparent bridging between two

routers over a serial interface (s0). Bridging will occur
between the two Ethernet Interfaces on Router A (e0 and e1)

5.3 CONNECTION TO THE LINE INTERFACE MEDIA

Instructions for connecting the line interface media (twisted pair , or

fiber optic cable) are contained within the base unit user manual.
Please refer to the base unit manual for connection details.

5.4 CONNECTING TO AC OR DC POWER

Instructions for connecting the power supply Universal Interface

AC Power Supply and DC Power Supply option) are contained within
the base unit user manual. Please refer to the base unit manual for
connection details.

WARNING!

The Model IM1/I interface card has been

specifically designed to work with UI and DC versions of
Patton Electronics base units. Use with 120/230VAC
versions could result in damage to the unit. If you are
unsure of your base unit power supply, please contact
Patton Electronics technical support at (301)975-1000 or at
[email protected].

Notice!

Any terminal cable connected to the Model IM1/I

must be shielded cable, and the outer shield must be 360
degree bonded–at both ends–to a metal or metalized backshell.
