StrataCom - The IPX Product

The IPX Product

The cards in the original IPX system were:

• The PCC - The Processor Control Card - a Motorola 68000 based shelf control card
• The VDP - The Voice Data Processor - Implemented a VAD algorithm and packetized the voice
• The VCD - The Voice Compressor-Decompressor - Implemented ADPCM
• The TXR - The Transmit Receive Card - Implemented a T1 interface with packet queues
• The PIC - The Protection Interface Card - Allowed the T1 interfaces to be swapped

The cards in the second wave were

• The SDP - The Synchronous Data Processor - added V.35, RS-422, and RS-232 data to the IPX (this card was a very early use of Xilinx FPGAs & StrataCom was their largest customer for a time)
• The CDP - The Circuit Data Processor - Added E1 and integrated echo cancellation

The card in the third wave was

• The FRP - The Frame Relay Processor - Added Frame Relay to the IPX (implemented the SAR function in Motorola 56000 DSP's)
