1.3.3 Point-to-Point LAN Extension

A point-to-point configuration
consisting of an Access Point and a Remote unit. This provides a com-
munications link for transferring data between two locations.

1.3.4 Serial Radio Network Connectivity

The transceiver provides a path for serial devices to migrate to
IP/Ethernet systems. Many radio networks in operation today still rely
on serial networks at data rates of 9600 bps or less. These networks can
use the transceiver as a means to continue using the serial service, while
allowing the infrastructure to migrate to an IP format.
A Remote transceiver with its serial port connected to a GE MDS
serial-based radio, such as the MDS x790/x710, MDS TransNET and
others, provides a path for bringing the data from the older radio into the
IP/Ethernet environment of a Mercury-based system.

1.3.5 Multiple Protocols and/or Services

Prior to the introduction of Ethernet/IP-based radios, two radios were
often used to service two different types of devices (typically connected
