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
