based advanced TDMA PHY cable upstream
implementation.
Implements pre-equalization for improved
performance in heavily impaired cable channels.
Enables digital cable set-top boxes, modems and
telephony implementations.
Provides self-contained subscriber and headend system
with seamless interface between subscriber and
headend components.
Windows software for running test functions and
scripts enable user-based evaluation tools with fast
turn-up.
Windows software API for register, memory and
control access allows visibility to system performance
for design comparisons and tradeoffs.
