There is no direct mapping of E1 to DS3. The only way to connect the two is using an MPLS network.

A DS3 is 45Mbps. An E1 is 2Mbps. The bandwidth of 22.5 E1's can traverse a DS3.

In order to directly connect an E1 as would a T1 to a DS3 you would need an E3

An E3 is 34 Mbps and 16 E1's could connect to it.

What is the max e1 ckts on a ds3 circuit?

This question actually is unanswerable. A DS3 or T3 has 28 DS1 or T1's. A E3 has 16 E1's There is no comparison between the two. A DS3 moves data at 45Mbps an E3 is 34 Mbps. they can not directly connect together. This includes their subrates. An E1 can not connect directly to a T1 without a converter.

What are the 5 types of digital dedicated lines?

The five types of digital dedicated lines include T1, T3, E1, E3, and fiber optic lines. T1 lines provide 1.544 Mbps, while T3 lines offer 44.736 Mbps, primarily used in North America. E1 lines, common in Europe, support 2.048 Mbps, and E3 lines provide 34.368 Mbps. Fiber optic lines can offer significantly higher speeds and bandwidth, suitable for extensive data transmission needs.
