to the highest possible rate on a given loop length with a given

margin. The algorithm was first of it's type for this technology in

the industry. Subsequent, (less efficient) algorithm by a competitor

(Brooktree) was awarded multiple patents and generated millions of

dollars in revenue.

. Designed and implemented several innovative management algorithms,

including Telco's Remote Powering of CPE, FXO/FXS POTS channel

transport within an embedded HDSL timeslot, Lifeline POTS fallback

state machine and Doubler (back to back HTU-C + HTU-R) alarm
