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 DS1s are in an OC-192?

An OC-192 carries 5,376 DS1s, per Telcordia GR-253.

DS1s in an OC-192

Working

OC-192 → 192 × OC-1 (STS-1) → 28 × DS1

192 × OC-1 (STS-1) in each OC-192 Telcordia GR-253192 × OC-1 (STS-1). Channelized OC-192 is 192 STS-1s.
28 × DS1 in each OC-1 (STS-1) Telcordia GR-253Seven VT groups × four VT1.5 (DS1).

192 OC-1s
192 × 28 = 5,376 DS1s

Leftover capacity

1.652736 Gbit/s of each OC-192 line rate (9.953280 Gbit/s) sits outside 5,376 × 1.544 Mbit/s of DS1 line rate (8.300544 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 6,446.42, which floors to 6,446 DS1s by bit rate only. The standard mapping is 5,376. Use the mapping.
