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~
