2.2 DESCRIPTION

The Patton Model IM1/I4 QuikConnect™ is an Ethernet Bridge with built-in four (4) port hub. The IM1/I4 interface module provides LAN extension when used in conjunction with either the IM1/I, IM2RC/IA, or IM1/I4 modules. The module performs transparent Ethernet bridging and functions at the MAC level. As such, the mod- ule, and its communications infrastructure, is transparent to higher level protocols such as TCP/IP, DECnet, NETBIOS and IPX network protocols. Only broadcasts, multicasts, or frames destined for peered LAN are forwarded. The Model IM1/I4 is 802.3 compliant and supports PPP (RFC 1661) with Bridging Control Protocol (RFC 1638).

Once installed in the local Patton base unit, the Patton IM1/I4 works in a “plug and play” manner to forward LAN broadcasts, multi- casts and frames destined for the peered Ethernet LAN at the remote end (the Patton base unit at the remote end must be equipped with an IM/I, IM1/I4 or IM2RC/I module). Using the Patton IM1/I4, Ethernet LANs can be linked over leased 2-wire/4-wire, DDS, PCM and campus fiber circuits.

2.3 TYPICAL APPLICATION

The Model IM1/I4 QuickConnect™ is designed to plug directly into the rear of a Patton Electronics baseband modem (e.g. Model 1092A or 1095). The Model IM1/I4 is designed to be used as one of a pair of units. Figure 1 (below) illustrates a typical Model IM1/I4 instal- lation.
