The simple answer is: An E1 is 2Mbits/s, FE is up to 100Mbits/s Therefore up to 50 However I suspect the question needs a bit more explanation and context.
Ethernet over E1 converter (also called E1 network bridge) is to transmit Ethernet data over E1 network (PDH,SDH network etc). The Ethernet port connect to terminal device,computer,Ethernet switch,Ethernet router etc. The device's E1 port connect to mail network(PDH SDH etc).E1 over IP (TDMOIP) is to transmit the E1 data over ethernet IPnetwork. It transports the legacy E1 data through the existing Ethernet or IP network. The typical application is transmit voice and data over wireless radio network.
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.
There are 63 E1 in one STM 1
there are different network media,fiber,copper cable etc.to make communication in different media,need the media converter,for example,fiber media converter making the copper ethernet over fiber transmission,E1/ethernet converter making the ethernet over E1 conversion.
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

well E1 is added to many fooods and the thing is is that if you dont eat it you will doe a painfull death!
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.
