Quantity is how many containers you have. The result is how many tributaries fit, the path, and the leftover line rate. The choices stay in the URL, so you can share them.

How many E1s are in an E3?
An E3 carries 16 E1s, per ITU-T G.702.
16
E1s in an E3
Working
E3 → 16 × E1
- 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.
