The operation of the decoder is controlled by a
pager control address (1EH) in conjunction with
a pager data address (1FH). Upon receipt of a
valid call the data ready interrupt is generated.
The POCSAG paging code
The CCIR Radio paging Code No.1 (POCSAG
Code) is constructed according to the follow-
ing rules:
A transmission consists of a preamble fol-
lowed by a batch of complete code words. Each
batch begins with a synchronization codeword
(SC). The format of the signal is illustrated in
the following Figure.
E ach transmission begins with a preamble to
achieve bit synchronization. The preamble is
a pattern of one and zero; 10101010... re-
peated for a period of at least 576 bits.
Codewords are transmitted in batches. E ach
batch consists of a synchronization codeword
followed by 8 frames. Each frame consists of 2
codewords. The eight frames are numbered 0
through 7. All pagers are similarly divided
into 8 groups. Each pager is assigned to one of
the 8 frames according to the 3 least signifi-
cant bits (LSB) of its 21-bit identity code (ad-
dress). The 3 bits are called “Receiver Identity
Code” (RIC).
