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.
This is an odd if not obvious question to answer. If you go to http://www.telegeography.com/products/map_traffic/index.php you will see that there are millions of fiber optic cables running under the ocean, under the ground, in drainage pipes, and on telephone poles. You'll find fiber in the oddest places. Ever notice that 6 inch wide cut in the street that runs for miles? Fiber. Fiber is the backbone of all data, voice, telemetry, and other types of commutations. It's capacity to carry (depending on the type of fiber) data at light speed, millions of connections at one time is unsurpassed.. One simple strand of fiber can carry more than one stream of data. Different spectrums of light are utilized to maximize capacity. Typically one cable contains mutable fibers. Thus multiplying it's capacity. I seriously doubt that anyone cutting one under sea cable or even a terrestrial cable would cause much damage. The redundancy and nature of the Internet and telecommunications world is (in many cases) over built. If one cable goes down, another takes over. The Internet was designed this way for military purposes. Before the Internet existed it was called ARPANET. It carried both military and public data. The network was split due to security issues. Now we have the Internet and Milnet. Many engineers believed that the deployment of fiber would not be rapid enough to feed the growth of the Internet and other networks. At one point Bill Gates was about to deploy over 800 LEO (low earth orbit) satellites. The fiber beat him and the project was shelved. Before fiber all we basically had was copper and satellites. Copper's ability to handle data pales in comparison to fiber. I hope this answered the question. Justin Petersen

No. Carbon nanotubes are the strongest man-made fiber, spider silk is the strongest animal-made fiber, and linen (from flax) is the strongest natural plant fiber.
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
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
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/

A DS3 can do 45Mbps Bidirectional Simultaneously.
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
T3 is the same as DS3. DS3 is a 45Mbps Data Circuit
A DS3 can do 45Mbps Bidirectional Simultaneously. That is 5.63 MBps
