Point-to-Point System

A point-to-point configuration (Figure 6) is a simple arrangement con-
sisting of just two radios—a master and a remote. This provides a sim-
plex or half-duplex communications link for the transfer of data between
two locations.

Tail-End Link ("MAS Extension")

A tail-end link can be used to extend the range of a traditional (licensed)
MAS system. This might be required if an outlying site is blocked from
the MAS master station by a natural or man-made obstruction. In this
arrangement, an MDS 9810 radio links the outlying remote site into the
rest of a licensed MAS system by sending data from that site to an asso-
ciated MDS 9810 installed at one of the licensed remote sites. (See
Figure 7).
As the data from the outlying site is received at the licensed remote site,
it is transferred to the licensed radio (via a local cable connection) and
is then transmitted to the MAS master station in the usual manner. Addi-
tional details for tail-end links are given in Section 4.3 (Page 21).
