MPC Data Protocol
From Zenitel Wiki
The AlphaCom supports a subset of the MPC data protocol used with the classic Stentofon TouchLine exchanges. As it allows control of the AlphaCom exchange by mapping MPC commands to AlphaCom commands one-to-one it can be thought of as a variant of the simple link layer, but only for single-exchange (not AlphaNet) applications.
The output is broadcast of exchange events like dialled digits, station busy/free, connection and transfers. Note that it’s possible to send additional data strings from the AlphaCom’s Event Handler on this port also.
The AlphaCom supports a subset of the MPC Data Protocol for backward compatibility. This allowed some TouchLine generation equipment like PNCI, MLH and CRM to be used with the AlphaCom.

Availability
AlphaCom has supported a serial data port which outputs TouchLine formatted output messages since AMC 03.00. From software AMC 07.60, a limited subset of TouchLine input commands are supported also.
Disclaimer
The TouchLine input commands have been implemented by translating them to existing AlphaCom data protocol commands. This means that the commands may not behave 100% identical compared to a TouchLine exchange in all possible situations. You should think of it as a simple ASCII link layer protocol to AlphaCom functionality.
