I see what you did there, Gleek.

That guy says it's fine. As do others I've found. I have a call into US Signal for their advice.

Taking a single CAT cable and splitting the pins in the manner suggested increases the likelyhood of head end attenuation and may compromise the EMI and crosstalk protection along the length of the cable as well.
The proper way to terminate a T1 beyond the Dmark is using T-Span Cable. It’s what we use when quoting the extending of a Dmark ($3.60 per foot)
Some use Cat5
Others use Cat3
Bottom line is it “Should” work, but in this business no hard and fast rules exist.

I did a training course on a Siemens SMX 2100 about 12 years ago and I remember that the real telco guys were concerned they might get shocked by all the bare terminals labelled T1 until the instructor pointed out that they were not real T1s but at a lower voltage. The instructor also said the 1.5Mb/s of a T1 was based on the distance between the telco manhole covers in New York - they thought New York would use the most T1s and they could throw a repeater down each telco manhole. Given the tech at the time they ended up with 1.5Mb/s as what was a safe signal to transmit that distance.
