You did notice that I was doing the calculation for 33600bps?

David,
 
I want to thank you for posting the above formula for calculating file
transfer speeds. I made up a chart for x2 transfer speeds by
extrapolating from average 300-33600 speeds. Your formula shows that my
table to be within 1% of calculated speeds.
 
Mike's posting caused me to try the formula to confirm his and your
figures. 31200 calculates to 3637 cps which confirms what Mike said.
However 33600 calculates to 3917 cps so it looks like your calculator or
typing finger needs a tune-up. (g)

Subj: inside wiring

MF> Not 12 gauge, 22 gauge.
Mike, the original message which you quoted was discussing the use of Romex 
12/2 or 12/3 wiring.

Ummm.... 12 gauge armour wire might be a trifle of overkill for phone use.
