IMPORTANT SAFETY INSTRUCTIONS For your safety, it is important to read and follow these instructions before operating a CCI-22 dual channel party-line interface: (1) WARNING: To reduce the risk of fire or electric shock, do not expose a CCI-22 dual channel party-line inteface to rain or moisture. Do not operate a CCI-22 dual channel party-line interface near water, or place objects containing liquid on it. Do not expose a CCI-22 dual channel party-line interface to splashing or dripping water.
CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN This symbol alerts you to the presence of uninsulated dangerous voltage within the product's enclosure that might be of sufficient magnitude to constitute a risk of electric shock. Do not open the product's case. This symbol informs you that important operating and maintenance instructions are included in the literature accompanying this product.
1 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”.
OPERATION In normal use, the CCI-22 interface does not require operator interaction. The front panel features a set of level controls and a power indicator LED. The front panel also includes a set of three "null" adjustment controls. The null adjustment controls are discussed in “Installation”, Chapter 2.
2. Plug the accessory earphone into the front panel jack labeled "Test". This will disconnect the interface from the matrix and enable the test oscillator. The oscillator produces a square wave with both low and high harmonics, allowing you to test all frequencies. The test tone pulses approximately every half-second. 3. While listening to the test tone in the earphone, adjust the "R" control until the tone is at a minimum. 4. Repeat Step 3 with the "L" and "C" controls.

2 INSTALLATION INTRODUCTION This chapter describes the installation of the CCI-22 dual party-line interface, including setting internal jumpers, wiring to external devices, and setting front-panel controls and indicators. INSTALLATION IN INTERFACE FRAME To install the CCI-22 interface module in the IMF-3 or IMF-102 interface frame: 1. Select a slot in which to install the interface. 2. Remove the blank plate covering the slot. 3. Set any Party-Line Termination Jumpers as necessary. 4.
located near the center of the CCI-22 main circuit board, and are shown as a detail in the assembly drawing for the CCI-22 main circuit board in the Maintenance Chapter. When either jumper is next to the label “B”, its termination is disabled; moving the jumper next to the label “A” enables the termination. WIRING The CCI-22 interfaces are connected to the matrix frame through the two RJ-45 connectors on the IMF-3 or IMF-102 rear-panel assembly (part no. 710538Z) to which CCI-22 is connected.
The power pin has a DC filtering circuitry to provide a high impedance for the audio so the power can be received from a “powered line or TW line” as is common with RTS systems. For TW operation tie the AUDIO and POWER pins together. Each party-line channel requires exactly one termination circuit. The termination circuit is usually built into the system component providing the party-line’s power.

3. Set the termination jumper for each CCI-22 channel to position “A” (termination connected) as described in “Termination of Party-Lines.” If the power supply does not have a termination-disconnect switch, wire the system as shown in Figure 2-5 on page 2-5. In this configuration, only the power supply channel’s power and ground lines are connected to the party-line. Note: Do not connect the power supply output’s terminated audio line to the party line.

TO CONNECT “RTS” 2-CHANNEL 2-WIRE PARTY-LINES Stations on RTS 2-channel 2-wire party lines are connected with 2-conductor shielded cable. One of the two shielded conductors carries both the DC power and the audio signal for one channel, while the other conductor carries audio only providing two channels per cable. The shield is a common ground for both channels. The matrix can be connected to a 2-channel 2-conductor “RTS” line using the CCI-22’s two channels. The CCI-22 does not support RTS call signals.
Power from “Channel A” Line Only Figure 2-8 shows only one non-Clear-Com channel powering both CCI-22 channels. The grounds are connected near the CCI-22’s DB9 connector.

ADJUSTMENTS POWER LED The green “PL Power” LEDs indicate whether the interface channels are getting +30 VDC power from the external party line to which they are connected. LEVEL CONTROLS The “Send” level controls affect the level of the audio signals from the matrix to the external party line. The “Recv” level controls affect the level of the audio from the party line to the matrix. The level controls have a range of ±13 dB; they are normally set to the midrange position.
test tone is minimized. Continue adjustment until the tone is minimal. If a deep null cannot be obtained, it is likely that something is wrong either with the wiring in the external party line or with one of the other devices attached to it. Following are some troubleshooting hints if a deep null cannot be obtained: • If the “R” control is turned fully counter-clockwise, the line has either more than one termination, or an excessive resistive load.
