For example, in voice, Tc=125 msec may cause pain :)

A minor correction about "frame-relay traffic-rate" commend in the
map-class frame-relay.
After you specified traffic-rate, everything displayed will be in
bit-per-second, but internally all other values, such as Bc, Be, CIR,
mincir are still be calculated in tc=125ms.
