+DESCRIPTION
The purpose of the paging transmitter is to provide a modulated, high-level RF signal,
which sets off pagers within the coverage area of its associated antenna. The paging trans-
mitter receives modulation and control information from the transmitter controller, which
receives information from a control site. In a simulcasting environment, the control site
may feed several paging sites at once.
