How many DS2s are in an OC-768?

An OC-768 carries 5,376 DS2s, per Telcordia GR-253.

DS2s in an OC-768

Working

OC-768 → 768 × OC-1 (STS-1) → 7 × DS2

768 × OC-1 (STS-1) in each OC-768 Telcordia GR-253768 × OC-1 (STS-1). Channelized OC-768 is 768 STS-1s.
7 × DS2 in each OC-1 (STS-1) Telcordia GR-253Seven VT groups, one VT6 (DS2) each.

768 OC-1s
768 × 7 = 5,376 DS2s

Leftover capacity

5.879808 Gbit/s of each OC-768 line rate (39.813120 Gbit/s) sits outside 5,376 × 6.312 Mbit/s of DS2 line rate (33.933312 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 6,307.52, which floors to 6,307 DS2s by bit rate only. The standard mapping is 5,376. Use the mapping.
