Caution:

It is recommended to select the DIP switch of Router 2 and 4-Port CE1/PRI MIM and modules in this way: when connecting 75-ohm cable, flip BIT1-8 to ON, and when connecting 120-ohm cable, flip BIT1-8 to OFF. Positions of DIP switches can only be changed by the trained personnel.

By default, all of the DIP switches of Router 2 and 4-Port CE1/PRI MIM and modules are factory-configured to ON, that is, the impedance of E1 interface is 75-ohm.
