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 DS2s are in an OC-1?
An OC-1 carries 7 DS2s, per Telcordia GR-253.

DS2s in an OC-1
Working
OC-1 (STS-1) → 7 × DS2
- 7 × DS2 in each OC-1 (STS-1) Telcordia GR-253Seven VT groups, one VT6 (DS2) each.
- 7 DS2s
Leftover capacity
7.656 Mbit/s of each OC-1 line rate (51.840 Mbit/s) sits outside 7 × 6.312 Mbit/s of DS2 line rate (44.184 Mbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
By bit rate only
Dividing the line rates gives 8.21, which floors to 8 DS2s by bit rate only. The standard mapping is 7. Use the mapping.
