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 DS3s are in an OC-1?
An OC-1 carries 1 DS3, per Telcordia GR-253.

DS3 in an OC-1
Working
OC-1 (STS-1) → 1 × DS3
- 1 × DS3 in each OC-1 (STS-1) Telcordia GR-253Asynchronous DS3 mapping into the STS-1 synchronous payload envelope.
- 1 DS3
Leftover capacity
7.104 Mbit/s of each OC-1 line rate (51.840 Mbit/s) sits outside 1 × 44.736 Mbit/s of DS3 line rate (44.736 Mbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
