Ok, we're both wrong. :-)

RJ48S is the DDS 56K standard, and is wired the way I mentioned.  I did some 
radio station digital STL's over 56KDDS circuits in my former position as a 
broadcast engineer, and misremembered.

The T1 standard is RJ48C, and is wired the way you mentioned.  Argh.  Long day 
fighting the firewall....
