MDS iNET 900 - Point-To-Point LAN Extension; Backhaul for Serial Radio Networks

1.2.2 Point-to-Point LAN Extension
A point-to-point configuration (Figure 1-3) is a simple arrangement
consisting of an Access Point and a Remote unit. This provides a com-
munications link for the transfer of data between two locations.

1.2.3 Backhaul for Serial Radio Networks
One of the primary design features of the iNET design provides a path
for serial devices to migrate to IP/Ethernet. Most radio networks in oper-
ation today rely on serial networks at data rates of 9600 bps or less.
These networks can use an iNET as the means to continue using the
serial service, while allowing the rest of the infrastructure to migrate to
an IP format.
Operational radio networks built with MDS radios, such as
MDS 9790/9710 and MDS 9810, can be supported by an iNET 900
Remote using one serial port for the data stream, and the other for net-
work-wide diagnostics. In the case of older MDS radios, where a single
port is used for data and diagnostics, the capabilities are doubled. The
data streams are delivered to an IP socket in an application, or in serial
format using the Access Point.
