Analog Tones

Analog tones can be sent as a two-tone or ﬁ ve / six tone format. The two-tone analog paging technique

transmits two sequential audio tones, of different tone durations, to address a pager. The ﬁ ve / six tone

analog paging format was an improvement on the two-tone format, in that it can address more pagers

and can also save battery life in the pagers by addressing in groups (a group of pagers not addressed,

will not come out of sleep mode, saving battery life). The analog tone encoding format can support tone

only as well as tone and voice paging. In a voice page, after transmitting the tone and waiting a short

period, the speaker of the pager is connected directly to the analog signal so that transmitted analog

voice signals are heard on the pager.

Other Paging Protocols

There are many other paging protocols such as the Swedish MBS format, NEC, ERMES (the European

Radio Message Standard), and ReFLEX™, Motorola’s two-way paging protocol.
