MCPC - Multi Channel per Carrier

Multiple Channel Per Carrier refers to the multiplexing a number of digital data channels into a common digital bit stream, which is then used to modulate a single carrier that conveys all of the services to the end user.

The single carrier supports multiple communication channels, hence the term "multiple channel per carrier". These channels can be video, audio, telephony and data services. The term MCPC is frequently used in the context of DVB (Digital Video Broadcasting) systems, where the composite digital signal is referred to as a MPEG-2 Transport Stream or DVB multiplex. Applied to telephony, MCPC is a byproduct of SCPC (Single Channel per Carrier) combined with conventional TDM voice/data multiplexing.

MCPC - Multi Channel per Carrier; Typical Content solutionMulti Channel per Carrier is is the most popular method of satellite communications in the deregulated international markets driven by user demands.

Example: A VSAT Network provides a point to point satellite link between a Rural Automatic Exchange (RAX) and a Trunk Automatic Exchange (TAX) in a star configuration Each MCPC link provides a total of seven 16 Kbps channels out of which 6 voice/fax/data channels are for the users and one, multiplexed with 4.6 Kbps order wire, 9.6 Kbps voice/data and 1.8 Kbps ESC (Engineering Service Channel), is for the maintenance purpose.
