How many STM-4s are in a STM-64?

Working

STM-64 → 16 × STM-4

1. 16 × STM-4 in each STM-64 ITU-T G.70716 × STM-4.

• 16 STM-4s

Leftover capacity

0 bit/s of each STM-64 line rate (9.953280 Gbit/s) sits outside 16 × 622.080 Mbit/s of STM-4 line rate (9.953280 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
