An interesting article. A couple questions/comments:

What is: silence suppression. I laughed at first, but it must be time-compression that just encodes the duration of the silence in a small number of packets and recreates 'real-time silence' on the other end. It wouldn't seem there'd be much bandwidth savings. It only saves bandwidth if someone else can use it. Seems too sparse and uncorrelated to other channels to be of much practical use, BWDIK.

<<The evolutionary cycle quickly will move to six channels, then 12 and, within a year, there will be DSPs capable of running a T1's worth of channels on a single chip, Gellman says. "Next year, we'll see a single board with capacity to handle T3 (45 megabits per second [mbps]) sitting behind a 5ESS," he adds.>>

Seems a bit ambitious to me.

"The next step is to move from .42 micron to .25 micron [semiconductor circuit] technology, which we already have in house."

Nothing particular here, except that it surprised me. TI's bleeding edge multi-core DSP's are already fabbed in .18u I believe. I assume that's the TI product they refer to for the T3 case due to the large MIPS requirement to process so many channels simultaneously.


oop, gotta run. more later
