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 ODU2?
An ODU2 carries 192 DS3s, per ITU-T G.709 and ITU-T G.707. This path maps STM-64 into ODU2 as a client, then follows that client's tributaries.

DS3s in an ODU2
Working
ODU2 → 1 × STM-64 → 64 × STM-1 → 3 × DS3
- 1 × STM-64 in each ODU2 ITU-T G.709Client mappingCBR STM-64 mapped into OPU2.
- 64 × STM-1 in each STM-64 ITU-T G.70764 × STM-1.
- 3 × DS3 in each STM-1 ITU-T G.707Three VC-3s, each able to carry a DS3.
- 1 STM-64
- 1 × 64 = 64 STM-1s
- 1 × 64 × 3 = 192 DS3s
Leftover capacity
1.447961924 Gbit/s of each ODU2 line rate (10.037273924 Gbit/s) sits outside 192 × 44.736 Mbit/s of DS3 line rate (8.589312 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
By bit rate only
Dividing the line rates gives 224.36, which floors to 224 DS3s by bit rate only. The standard mapping is 192. Use the mapping.
