Technologies: IP stack, HTTP/S protocols, ethernet, LANs, IP layers 2/3/4, OpenWRTSynopsis: comScore is a data collection service. I wrote client code to collect URLs, data, stats, byte counts, etc. for the eventual upload to servers for collation, graphing and finally sales. Development involved teamwork with a number of other engineers. Technologies.

Sterling, VA, USA (and Montreal, Canada)

Technologies: ISIS, VxWorks, NetBSD, GNU tools, layer 3Synopsis: Hyperchip was building a petabit router. I helped modify GateD IP routing software. GateD is a freeware package that supports a number of IP, layer 3, routing protocols including BGP, OSPF and ISIS. My work involved the modification of ISIS to run under VxWorks and NetBSD.

Sterling, VA, USA

Technologies: Solaris clonable streams driver, TCP/IP, layer 2Synopsis: IPOptical was building a petabit router. I wrote a Solaris layer 2.5, clonable streams driver, which I plumbed into the Solaris TCP/IP stack. This layer provided inter-processor communication for the router.

Reston, VA, USA

Technologies: PC telephony, Natural Microsystems, Linux, Solaris, VRU, REXX scripts, OracleSynopsis: PriceInteractive sold VRU (Voice Response Unit) services to AT&T, Sprint, banks and numerous other businesses. I wrote a Solaris based VRU using Natural Microsystems PC telephony cards.

Herndon, VA, USA

Technologies: outbound dialing, Mitel, Zarlink, Natural Microsystems, firmware, T1, 68000, ksh, bash scriptsSynopsis: ITC sold an outbound dialer. I designed the telephony portion of this dialer using Mitel components. This included all the hardware (analog line circuits, analog trunk, T1 trunk, crosspoint, conference circuit, DTMF sender, etc.). I also.

Reston

Technologies: X.25 packet switching hardware, 68000, DRAM, T1Telenet was an originator of X.25 packet switching technology and services. I worked on various components including switching and transmission over T1 spans.

Kanata, Ontario

Technologies: 68000, DMA, DRAM, crosspoint switches, DTMF, conferencing, Digital Signal Processing.Mitel was a major manufacturer of TDM based PBXs. I designed the common control for the SX200D, a 200 digital, TDM line PBX. This included the processor, DRAM, and a DSP for DTMF tone generation and conferencing. I developed a means to message between.

Brockville, Ont. Canada

Technologies: #5 Crossbar, Strowger switches, DTMF senders/receivers, dial pulse signalingSynopsis: GTE was a common carrier and major manufacturer of telecom equipment. At GTE I was credited with developing a universal multi-frequency ringing generator and a loop powered ring code detector for party lines.

Victoria, BC, Canada

I published a paper on a high speed smear camera I designed and built.

Montreal, Canada Area

CP Tel was upgrading from a circuit switched 33 milliamp current loop data transmission network, to a fully digital, nationally synchronized data network. I worked on the clock recovery system, which was based on an Austron LORAN C, RF clock receiver.
