digital circuit multiplication equipment (DCME)

Digital Circuit Multiplication Equipment (DCME) is a multiplexing technique that optimizes the available bandwidth oftransmission systems

. DCMEs are circuit multipliers that were already used years ago in cost-intensive transmission systems used for voice communication, such as in submarine cables

or satellite connections.Circuit multipliers use the pauses in speech communication and transmit additional information

during these pauses.

Statistically, a telephone conversation consists of about 60% pauses, a fact that DCME technology takes advantage of. The

interface functions and performance specifications of DCME are described in the ANSI T1 reference lists under T1.309-1990. In addition, the International Telecommunication Union (ITU) addresses line multiplier sizing in Recommendations E.528 (02/96).
