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.
I know Murray is making this test hard! lol. anyway. its T3
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.
In sdh radio 63 E1's are there
There are 63 e1's in sdh STM-1 = 63 x E1; STM-4 = 63 x 4 E1; STM-16 = 63 x 16 E1; STM-64 = 63 x 64 E1.
Bmi- T3 British Airways- T3 Flybe- T3 Lufthansa- T1 * All these airlines go to Dusseldorf.
There are 63 E1 in one STM 1
There are 28 T1 carrier lines in a T3 connection.
84
STM-0= 21 E1 lines STM-1=(64x1) - 1 = 63 E1 lines STM-4=(64x4) - 4 = 252 E1 lines STM-16=(64x16) - 16 = 1008 E1 lines STM-64=(64x64) - 64 = 4032 E1 lines and so on
2 mb
well E1 is added to many fooods and the thing is is that if you dont eat it you will doe a painfull death!
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.
