How many DS3s are in a STM-0?
A STM-0 carries 1 DS3, per ITU-T G.707. This is a client mapping of DS3 into STM-0.

Leftover capacity
7.104 Mbit/s of each STM-0 line rate (51.840 Mbit/s) sits outside 1 × 44.736 Mbit/s of DS3 line rate (44.736 Mbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
