A DS3 can do 45Mbps Bidirectional Simultaneously.
DS3 bandwidth can reach speeds of up to 45 Megabits per second on both upload and download. It can both upload and download simultaneously without speed loss.
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.

There are 3 DS3's in an OC3. Generally an OC3 or higher capacity circuit will be used to deliver a DS3 due to distance limitations of the DS3. http://www.intelletrace.com/internet-services/OC3-Internet-Services.html www.intelletrace.com Wholesale Internet for Business
DS3 is 44.7 Mbps and a T1 is 1.55 Mbps. So 1 DS3 = 28 T1s http://www.dslbroker.com/ds3.html
A DS3 has 28 T1's http://techblog.intelletrace.com/what-is-a-ds3-hub/
3 ds3 in stm1
how many DS3's are in an OC192
672 DS0 make 1 DS3
an OC48 has 48 DS3's.
T3 is the same as DS3. DS3 is a 45Mbps Data Circuit
A DS3 can do 45Mbps Bidirectional Simultaneously. That is 5.63 MBps
