How many DS0s are in an E0?
An E0 carries 1 DS0, per ITU-T G.702.
1
DS0 in an E0
Working
E0 → 1 × DS0
- 1 × DS0 in each E0 ITU-T G.702E0 and DS0 are each one 64 kbit/s PCM channel.
- 1 DS0
Leftover capacity
0 bit/s of each E0 line rate (64 kbit/s) sits outside 1 × 64 kbit/s of DS0 line rate (64 kbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
