REMOTE PAGING
Remote Paging connects the base paging transmitter to the remote paging transmitter through an
MT-4E radio link for greater paging coverage. The paging encoder (or terminal) feeds the paging
information to the paging network card which generates the PURC® tones which are transmitted to
a remote receiver. The PURC® tones are then sent to the transmitter controller which generates the
analog or digital paging format and sends them to the paging modulator and transmitter. Remote
paging is shown in Figure 2-3.
