How many ds1 in oc3?

An OC-3 circuit has a data rate of 155.52 Mbps. A DS-1 line, also known as T1, has a data rate of 1.544 Mbps. To determine how many DS-1 lines are in an OC-3, you divide the OC-3 rate by the DS-1 rate: 155.52 Mbps / 1.544 Mbps ≈ 100. Therefore, an OC-3 can carry approximately 100 DS-1 lines.
