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 OC-3s are in an OC-12?
An OC-12 carries 4 OC-3s, per Telcordia GR-253.
4
OC-3s in an OC-12
Working
OC-12 → 4 × OC-3
- 4 × OC-3 in each OC-12 Telcordia GR-2534 × OC-3. Channelized OC-12 is 12 STS-1s.
- 4 OC-3s
Leftover capacity
0 bit/s of each OC-12 line rate (622.080 Mbit/s) sits outside 4 × 155.520 Mbit/s of OC-3 line rate (622.080 Mbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
