AMI with 24 channels is 1344000bps (56000 by 24).  (A continuing
crisis with many LECs is that data links are set up as AMI/D4, when
there's usually no reason not to run B8ZS/ESF.  When our drop was put
in, the technician installed the B8ZS/ESF line, then proceeded to
configure the CSU/DSU for AMI/D4.  Sigh.)
