Re: Clear Channel on a T1

["Terrence Chatfield" <chat () gemnets com>]

    If this T-1 is for internet service, then what AT&T is charging you extra dollars
for is the ability to send more data through their network (port charge). 1.536 Mbps max
data rate for clear channel, vs 1.344 Mbps max data rate for non-clear channel.  There
should be no additional charge for the local loop, since all modern telecom equipment
inherently support both flavors of T-1s.
