| RJ48C is *not* standard ethernet cable. The twisted pairs are grouped 
| differently. Ethernet cables work OK for T1s if they are only 2 or 3 
| metres long. Long ethernet cables give high error rates when used for T1s.

According to the t1 techs I've been dealing with, a standard ethernet cable
will work (we have been using a 3 foot segment approx 1m)  In fact the only
configuration that lights all lights is a standard ether cable. T1 cross-over
doesn't create a proper link and lights on the t100p and smart jack indicate
a failed condition.
