I will see if I can perform that test on Monday AM and post the results. BTW,
the typical propogation delay through all the controllers is less that 5mS, so
pretty fast.

Incidentally, the Link-Comm board uses the 2.2 uF cap / pin 10 combination to
drive the COS output buffer... FWIW

an SCom 7k. I've always attributed it to COS line propagation delay in the
controller, but perhaps the 2.2 µF cap is the major culprit. We solved the
problem by using the onboard audio gating, which I see uses pins 6 & 7 of the
Micor squelch IC.
Maybe we can ask Link-Comm to do a timing test on their unit and then change
the 2.2 uF capacitor on pin 10 to something else and see if it changes the
attack/decay of the COS action?
Steve or Allan - you out there?
