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.
E1 is coaxial cable @2Mbps, compared to ethernet@10/100Mbps, Coaxial cable very expensive compared to ethernet.
There is no difference; Ethernet is Ethernet, regardless of where it is deployed.
Gigabit Ethernet almost always runs in full-duplex mode
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.
Unframed E1, you will be able to use the full bandwidth of the circuit of 2048 kpbs. Normally, for various reasons, this mode is not given to customers by telco. Costly service Framed E1 ,you will be able to use 1984Kbps only from 2048Kbps where timeslot 0 is reserved for sync and signaling purposes. Less costly when compared with Unframed.

The relationship between Xerox PARC and Ethernet is that the Ethernet was invented at Xerox PARC.
In Technical Terms RRI is a Soft Push and FIU is a hard because when there is an electrical E1 droping we need FIU.
The nic is a network adaptor modem is a device to communicate with a remote
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.

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.
FE means Fast Ethernet having bandwidth 100 Mbps ,SFP 850 nm or 1310 nm GE means gigabit Ethernet hving bandwidth 1000Mbps ,SFP 1550 nm
