Abstract Personal Communications Manager (APCM)

ABSTRACT

The Abstract Personal Communications Manager (APCM) is an Application programmers Interface (API) for telecommunications, providing simple and powerful interaction between communication applications and protocol software for circuit switched connections and transmission of voice and data. A few generic service primitives are developed through abstraction of the various call control operations.
