2.2 DESCRIPTION
The
Patton IM1/I
QuikConnect™
Ethernet WAN bridge module
installs in Patton’s copper and fiber base units to provide seamless
Ethernet LAN extension. The Patton IM1/I performs the bridging
function between two physically separate Ethernet LANs at the MAC
level. Operation of the Patton IM1/I is transparent to higher network
level protocols such as TCP/IP, DECnet, NETBIOS and IPX. The
Patton IM1/I is 802.3 compliant and supports PPP (Point to point
protocol) with bridging control protocol (RFC 1638).
Once installed in the local Patton base unit, the Patton IM1/I works
in a “plug and play” manner to forward LAN broadcasts, multicasts and
frames destined for the peered Ethernet LAN at the remote end (the
Patton base unit at the remote end must also be equipped with an IM1/I
module). Using the Patton IM1/I, peered Ethernet LANs can be linked
over leased 2-wire/4-wire, DDS, PCM and campus fiber circuits.
