APOC
Advanced Pager Operating Code. A new mode, developed by Philips
Telecom and announced in 1993, that offers higher speed and some new
features while retaining backwards compatibility with POCSAG. Supports
bit rates between 1200 to 6400 or about 1200 to 3200 baud using 2-PAM/FM
or 4-PAM/FM modulation. Extended addressing is supported, allowing
support for more then 2 million pagers. As of mid-1996, Philips has
dropped APOC and instead settled a cross-licensing deal with Motorola
for access to FLEX.
