How many STM-1s are in a STM-64?

Working

STM-64 → 64 × STM-1

1. 64 × STM-1 in each STM-64 ITU-T G.70764 × STM-1.

• 64 STM-1s

Leftover capacity

0 bit/s of each STM-64 line rate (9.953280 Gbit/s) sits outside 64 × 155.520 Mbit/s of STM-1 line rate (9.953280 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
