How many DS1s are in a DS2?

Working

DS2 → 4 × DS1

1. 4 × DS1 in each DS2 ANSI T1.107Four DS1s, bit-stuffed up to the 6.312 Mbit/s DS2 line rate.

• 4 DS1s

Leftover capacity

136 kbit/s of each DS2 line rate (6.312 Mbit/s) sits outside 4 × 1.544 Mbit/s of DS1 line rate (6.176 Mbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
