Typical Connection Diagram
Rm and CM provide the impedance match with the telephone line. These values are country dependent.
The chart below show the correct Rm and Cm values and correct XE10X0 model for various countries.
VR1 provides protection from voltage surges on the telephone line. The table below show the
recommended breakdown voltage for VR1.
