... EXTRACTION LOGIC RES A1 Rev. 3.1 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 kbit/sec channels multiplexed to/from a 2048 kbit/sec serial PCM bit stream ...

... These are the inputs for primary rate PCM input streams VDD Positive Supply Voltage Data Bus I/O Port. These are the bi-directional data pins to the microprocessor interface. Only 5 bits are used when data is written into AS3588A (D4 to D0) Data Ready Output. DR This active high signal goes low for signalling purposes Page ...

... OP OUTPCM 7 to OUTPCM 4 Functional Description The AS3588A is a digital time / space crosspoint switching matrix and is designed to switch data from eight primary rate input ports operating at 2048 kbit/s to eight primary rate 2048 kbit/s output ports. Simultaneously it allows its controlling microprocessor to read PCM output channels or write to PCM output channels (Messaging) ...

... OR2 should be carried out with separate read strobes which are responsible of stepping through the instruction flow. Software Control AS3588A performs two switching functions and four auxiliary functions for diagnostic purposes and data in- sertion from the microprocessor interface. 1) PCM CHANNEL CONNECTION This function connects a PCM input channel to a PCM output channel ...
