The 2-port E1/CE1/PRI MIM provides 8 internal DIP switches. The settings of the
DIP switches determines the interface impedance and grounding mode, as
described in Table 34.

Module
DIP Switch S1
E1 Interface Interface 0
By default, all DIP switches are switched on so the impedance of the E1 interface is
75-ohm.
