  • Page 7: Operation

    INTRODUCTION This chapter describes how to use the CCI-22 dual party-line interface. You can use this chapter once the Eclipse matrix system has been correctly installed and configured with the Eclipse Configuration System, and when the CCI-22's internal jumpers have been set. For information on configuring the CCI-22 jumpers refer to Chapter 2, “Installation”.

  • Page 11: Installation

    Although the CCI-22 is not designed to supply power to an external party-line system, each channel of the CCI-22 features a Clear-Com termination circuit that can be connected to the party-line by installing a jumper. This termination network is not normally connected, and should only be connected in the rare case that the external party-line does not include a termination circuit.

    Connecting more than one termination circuit to a party-line will impair the null and degrade the line’s audio quality. When a CCI-22 party-line channel is connected to a Clear-Com party-line, the Clear-Com/Other Select pin must be left floating.
