Damn straight ! <vbg>

Actually I'm glad to hear there are still that many guys that do 
networking & telephony on here!

For the rest of ya', and those that admonished me for not simplifying 
the equation, it was a sort of inside joke.  The US phone system uses 
a 64Kbit/sec standard for a digital voice line.  A T1 circuit 
time-division-multiplexes 24 of those onto a 1.54 Mbit/sec circuit 
commonly carried on two copper pairs.  When they started being used 
for Internet and WAN services, bandwidth was sometimes throttled down 
to a portion of the full available, for "fractional T1".  We pay 
about $595/month for a T1 circuit at work, and only half the 
bandwidth or about 768Kbs in & out -- Only a 3rd or less the speed 
than what you commonly get on residential cable/DSL but snappy 
outbound and very reliable.  Or if you're ~really~ 
curious:  http://en.wikipedia.org/wiki/Digital_Signal_1
