| Question 5 |
How many DS1 signals are transported on a DS3 signal ?
| 24 | |
| 672 | |
| 14 | |
| 28 |
Question 5 Explanation:
→ A Digital Signal 3(DS3) is a digital signal level 3 T-carrier. It may also be referred to as a T3 line.
1.The data rate for this type of signal is 44.736 Mbit/s (45 Mb).
2.DS3 uses 75 ohm coaxial cable and BNC connectors.
3.This level of carrier can transport 28 DS1 level signals within its payload.
4.This level of carrier can transport 672 DS0 level channels within its payload.
