Description

PT7A8980/8980L is designed to handle data in ST-BUS

format. It interfaces with a microprocessor to switch

PCM-encoded voice or data in application areas such as

modern digital exchange, PBX and Central Office.

PT7A8980/8980L can simultaneously connect up to 256

channels of 64 kbit/s each. It has 8 data stream inputs

and 8 data stream outputs. Each data stream consists of

32 multiplexed 64 kbit/s channels which is compatible to

2048 kbit/s ST-BUS format.

Its microprocessor interfaces not only allow access to

the internal registers and memory, but also provide means

to read from the input channels or to write to the output

channels.
