1. A telecommunications line surge protector comprising:

  • a housing;

    a first input connector connectable to a telecommunications line;

    a first output connector connectable to a telecommunications line;

    a first surge protection circuit, disposed within the housing, which connects the first input connector to the first output connector by at least two wires, including a first surge protection element that protects at least one wire from surges greater than a first limiting voltage, and including a second surge protection element that protects at least one other wire from surges greater than a second limiting voltage, where the first limiting voltage is different from the second limiting voltage;

    a second input connector connectable to a telecommunications line;

    a second output connector connectable to a telecommunications line; and

    a second surge protection circuit, disposed within the housing, which connects the second input connector to the second output connector by at least two wires, including a third surge protection element that protects at least one wire form surges greater than a third limiting voltage, and including a fourth surge protection element that protects at least one other wire from surges greater than a fourth limiting voltage, where the third limiting voltage is different from the fourth limiting voltage.
