KT8554B/7B
1 CHIP CODECS
INTRODUCTION
The KT8554B/7B are single-chip PCM encoders and decoders
(PCM CODECs) and PCM line filters. These devices provide
all the functions required to interface a full-duplex voice
telephone circuit with a time-division-multiplex (TDM)
system.
These devices are designed to perform the transmit encoding
and receive decoding as well as the transmit and receive filter-
ing functions in PCM system. They are intended to be used
at the analog termination of a PCM line or trunk.
These devices provide the bandpass filtering of the analog
signals prior to encoding and after decoding. These combina-
tion devices perform the encoding and decoding of voice and
call progress tones as well as the signalling and supervision
information.
