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-192s are in an ODU3?
An ODU3 carries 4 OC-192s, per ITU-T G.709 and Telcordia GR-253. This path maps OC-768 into ODU3 as a client, then follows that client's tributaries.

OC-192s in an ODU3
Working
ODU3 → 1 × OC-768 → 4 × OC-192
- 1 × OC-768 in each ODU3 ITU-T G.709Client mappingCBR OC-768, the same client rate as STM-256, mapped into OPU3.
- 4 × OC-192 in each OC-768 Telcordia GR-2534 × OC-192. Channelized OC-768 is 768 STS-1s.
- 1 OC-768
- 1 × 4 = 4 OC-192s
Leftover capacity
506.098983 Mbit/s of each ODU3 line rate (40.319218983 Gbit/s) sits outside 4 × 9.953280 Gbit/s of OC-192 line rate (39.813120 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
