5. Applications of FE1-4ETH Bridge
5.1 Definition of balanced twisted-pair wire sequence
5.1.1 100BASE-TX interface wire sequence
The RJ45 Unshielded twisted-pair for FE1-4ETH interface can use
DCE or DTE standard stipulations, it support AUTO MDI/MDX function.
5.1.2 E1 interface wire sequence
1 & 2 are transmitting lines, 4 & 5 are receiving lines, as shown below:
Figure 5 RJ45 balanced twisted-pair wire sequence for E1 interface
5.2 Setting of DIP switch and jumper
5.2.1 Setting of E1 interface impedance
Below are switch which allow user to set number of Time Slots according
to the expected rate : as shown by Figure 6 :
