How many E3s are in a STM-0?
A STM-0 carries 1 E3, per ITU-T G.707. This is a client mapping of E3 into STM-0.

Leftover capacity
17.472 Mbit/s of each STM-0 line rate (51.840 Mbit/s) sits outside 1 × 34.368 Mbit/s of E3 line rate (34.368 Mbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
