and CompuServe Frame Relay networks. The BPX, which was produced in 1993, increased the speed and sophistication of the Frame Relay offering. It also supported the 53 byte cells of the ATM standard instead the IPX's 24 byte cells. The original IPX product was also enhanced and re-introduced as the IGX. 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) StrataCom management and locations StrataCom's first CEO was Steve Campbell who later went to Packeteer. Dick Moley, who came from ROLM Corporation, served as its CEO for most of its existence. Dave Sant originally led sales, hiring Scott Kriens who later became CEO of Juniper Networks.

StrataCom went public in the fall of 1992 under the ticker symbol STRM. Three of its executives later formed SToRM Ventures. They were Tae HeaNahm, Ryan Floyd and Sanjay Subhedar Acquisition by Cisco Systems Cisco Systems acquired StrataCom in 1996 for US$4 billion.
