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.
