Contact your carrier immediately. ! Ensure that the following items were received with your shipment: Figure 1.1.
4 Introduction ~ Controls and Connections A C B D E F G Figure 1.3. AP10 rear-panel connectors Rear view A. Power. The AC power cord input is a NEMA-type connector allowing 100–240VAC, 50/60Hz. B. G-Link In, Out. This RJ-45 connector is used to connect the AP10 to the AP800 for control. AP-Ware is capable of accessing and controlling a G-Link local area network (LAN) of up to eight AP800/AP400 units and 16 AP10 units. G-Link supports a distance of up to 20 feet between each connected unit. C.
Introduction ~ Before You Install Before You Install Power requirements The AP10 automatically accommodates voltage requirements of 100–240VAC, 50/60Hz, 15W. Telephone line requirements The AP10 model operates on a standard analog telephone line and connects to the telephone system with a standard RJ-11C modular jack. If you do not have an RJ-11C jack where you want to install your AP10, call your telephone company for installation.

CHAPTER 2: Installation The AP10 is designed for easy installation and set-up. All connections are made through rear-panel connectors. This section provides instructions on installing the units in the rack and making initial connections, creating a G-Link network, and assigning device ID numbers. The diagram below illustrates the typical connections that are made when adding an AP10 to an AP800.
8 Installation ~ Hardware Setup A C B D E F G Figure 2.2. AP10 rear panel connectors 5. ✍ The three terminals in the Phoenix connector correspond with the backpanel audio contacts (from left to right): +(positive), –(negative), and (ground). + Wire the AP10 to the AP800 using the provided three-terminal Phoenix push-on connectors. These connectors are designed for easy wiring; simply insert the desired wire into the appropriate connector opening and tighten down the top screw.
9 Installation ~ Hardware Setup Assigning device ID numbers Once your physical G-Link network is established, you need to set up unique G-Link device ID numbers for each AP10 on the network. As shipped from the factory, all AP10 units default as binary address 0.

CHAPTER 3: Configuration DIP Switch Settings The AP10 has a variety of operational features configurable through DIP switch settings, including noise burst/auto-adapt, receive AGC control, auto-answer, autodisconnect, call progression/loop, receive reduction, and hook-flash duration. Default settings (as shipped from the factory) are denoted by an asterisk “*”. Figure 3.1.
12 Configuration ~ DIP Switch Settings Receive AGC DIP switch 3 enables/disables the automatic gain control (AGC) function in the firmware. The AGC feature is designed to keep soft and loud telephone participants at a consistent level. DIP Switch Position Description 3* On (up) Receive AGC enabled 3 Off (down) Receive AGC disabled Auto-answer ✍ To issue the AA (autoanswer) serial command to toggle auto-answer, DIP switch 4 must be off (down). DIP switch 4 enables/disables auto-answer.
13 Configuration ~ Calibration Receive reduction In some applications, it might be necessary to duck (lower) the receive audio coming in through the telephone line when transmit audio is present. To enable receive reduction, set DIP switch 7 to the On position. DIP Switch Position Description 7 On (up) Receive reduction enabled 7* Off (down) Receive reduction disabled Calibration The following information will help you make adjustments to optimize your system performance.
14 Configuration ~ Calibration Auto-adapt If DIP switch 1 is off (down), call someone and continue to talk while the system gradually adapts over time. Once complete, the AP10 will be fully calibrated and ready for use. Press the Off button [E]. If the auto-disconnect feature is active, and the caller hangs up, the AP10 will disconnect upon sensing loop drop or callprogress tones, depending on the position of DIP switch 6.
CHAPTER 4: Operation The AP10 has four basic functions: make a call, answer a call, disconnect a call, and mute. This chapter explains how to perform these functions with the AP10 unit and a telephone handset (optional) and with the Telco interface in AP-Ware. You can also use touch panels and custom control devices. Using the AP10 A B C To answer a call D E Figure 4.1.
16 Operation ~ Using the Telco Interface 3. When the conversation is complete, press the Off button [E] to disconnect the call. You can also disconnect using an external controller. If the handset is off hook, audio will be routed to the telephone. If your call is through the handset only (the red Off LED will be lit), hang up when the conversation is complete. Using the Telco Interface To make and disconnect a call 1. Open AP-Ware and select the AP10 unit. 2.
Operation ~ Controllers To mute • Click Mute TX to mute the transmit audio (audio sent to the telephone line). • Click Mute RX to mute the receive audio (audio from the telephone line). Other telco options • Hook-Flash. This button sends a momentary interruption in line seizure to the telephone line. • Re-Null. This feature sends a short noise burst down the telephone line and forces the AP10 to adapt to the telephone line. • Auto-Answer. This button turns auto-answer on and off.

Glossary Glossary Acoustic Echo Cancellation (AEC) A process in which acoustical echo is removed from a signal. AEC can be used to remove unwanted signals from mic audio if the unwanted acoustic signal is available separately as an electronic signal. Ambient Noise The existing room-level noise, such as that caused by ventilation systems, paper shuffling, and background chatter. Attenuation A reduction of signal amplitude.
34 Glossary Matrix mixer A mixer that allows routing of any input or combination of inputs to an output or any combination of outputs. Omni-directional Microphone A microphone that picks up audio in a 360-degree pattern. Reverberation Audio in a room that bounces off a wall, ceiling, table or other objects and then is picked up by microphone. High reverberation causes listener fatigue and makes audio difficult to understand.
