Best Answer

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 ds3?

A DS3 is a telecommunications circuit capable of transmitting and receiving 45 Mbps at the same time. A DS3 is generally delivered using an OC3 or higher capacity circuit then is muxed out to a DS3. A DS3 hands off as two 75Ohm coax cables.DS3 Cable Type734 Cable = 450 Feet (137.2M) RG59 Cable = 340 Feet (103.6M) 735 Cable = 225 Feet (68.8M) You can order this type of service from Intelletrace.com 415-493-2200

How many t1's ride on an oc3?

An OC3 breaks down to three DS3's. A DS3 Breaks down to 28 T1's. Therefore there are 84 T1's on an OC3. If you go one step further there are 672 DS0's on a DS3 or 2016 DS0's on an OC3. a DS0 is a 64k Channel equal to a single POTS line. http://techblog.intelletrace.com/what-is-a-ds3-hub/


How many t1 in a ds3?

DS3 is 44.7 Mbps and a T1 is 1.55 Mbps. So 1 DS3 = 28 T1s http://www.dslbroker.com/ds3.html


What is a T3 line?

T3 is the same as DS3 DS3 is a 44.736 Mbps Data Circuit or if channelized 28 T1's. T-carriers are made of multiple plain old telephone lines, but with many more channels (wires for transmission).
