description
The TCM29C13, TCM29C14, TCM29C16,
TCM29C17, TCM129C13, TCM129C14, TCM129C16, and TCM129C17 are single-chip PCM codecs
(pulse-code-modulated encoders and decoders) and PCM line filters. They provide all the functions required
to interface a full-duplex (4-wire) voice telephone circuit with a TDM (time-division-multiplexed) system, and are
intended to replace the TCM2910A in tandem with the TCM2912C. Primary applications include:
•
•
•
•
•
Line interface for digital transmission and switching of T1 carrier, PABX, and central office telephone
systems
Subscriber line concentrators
Digital-encryption systems
Digital voice-band data-storage systems
Digital signal processing
