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 ODU2?
An ODU2 carries 64 OC-3s, per ITU-T G.709 and Telcordia GR-253. This path maps OC-192 into ODU2 as a client, then follows that client's tributaries.

OC-3s in an ODU2
Working
ODU2 → 1 × OC-192 → 64 × OC-3
- 1 × OC-192 in each ODU2 ITU-T G.709Client mappingCBR OC-192, the same client rate as STM-64, mapped into OPU2.
- 64 × OC-3 in each OC-192 Telcordia GR-25364 × OC-3. Channelized OC-192 is 192 STS-1s.
- 1 OC-192
- 1 × 64 = 64 OC-3s
Leftover capacity
83.993924 Mbit/s of each ODU2 line rate (10.037273924 Gbit/s) sits outside 64 × 155.520 Mbit/s of OC-3 line rate (9.953280 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
