How many E1s are in an E3?

Working

E3 → 16 × E1

1. 16 × E1 in each E3 ITU-T G.70216 E1s, which is 4 E2s × 4 E1s.

• 16 E1s

Leftover capacity

1.600 Mbit/s of each E3 line rate (34.368 Mbit/s) sits outside 16 × 2.048 Mbit/s of E1 line rate (32.768 Mbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
