General Description

AS3588A is designed for switching PCM channels

under microprocessor control in digital exchanges,

PBX or Central Office equipment. It provides a non

blocking digital switching matrix for up to 256x256

64 kbit/sec channels.

Each of the eight serial inputs and outputs consists of

32 64 kbit/sec channels multiplexed to/from a 2048

kbit/sec serial PCM bit stream.

Simultaneously it allows its controlling microprocessor

to read PCM output channels or to write to PCM

output channels.
