CHAPTER 1: Introduction Congratulations on purchasing the XAP TH2 Telephone Interface.The XAP TH2 is a single-line digital hybrid which uses digital signal processing (DSP) to separate the transmit and receive audio, eliminating distortion, weak signals, and feedback. It continually filters low and high frequency noise to provide pure sound.

CHAPTER 2: Installation Hardware Setup The XAP TH2 is designed for easy installation and setup. All connections are made through rear-panel connectors.This section provides instructions on installing the units in the rack and making initial connections, assigning device ID numbers, and creating an expansion bus (E-bus) network. The diagram below illustrates the typical connections that are made when adding a XAP TH2 to a XAP 800. Figure 2.1.
8 Installation ~ Hardware Setup Figure 2.2. XAP TH2 back-panel connectors 3. The three terminals in the Phoenix connector correspond with the back-panel audio contacts (from left to right): +(positive), –(negative), and d(ground). ✍ 4. Plug your telephone set into the RJ-11C Set jack [C]. If you are using a custom controller for control and hybrid status, plug it into the DB-25 Remote connector [I]. If you are using an external RS-232 controller, connect it to the RS-232 port [H]. 5.

The maximum cable run between XAP 800/400 and PSR1212 units is 80 feet (24 ✍ Installation ~ Hardware Setup 3. The first XAP unit’s Expansion Bus Out connector is then attached to the Expansion Bus In connector on the next unit in the chain.
CHAPTER 3: Configuration G-Ware ClearOne’s G-Ware software provides an easy interface for configuring and controlling your XAP TH2.This chapter assumes you have already installed G-Ware and have created a site. If you need help installing G-Ware, creating a new site, or would like to see system requirements, consult the XAP 800 manual or help file.
12 Configuration ~ G-Ware 2. If you have already established a connection with the site, the Device ID will be assigned. If you are working offline, select the Device ID that matches the ID you assigned the unit via the back-panel DIP switches. Device IDs ensure the software will sync up with the proper unit when there are multiple TH2s on a network. 3. 4. Adjust the Meter Refresh rate as necessary. The default rate is 50ms. Select the country where this product is being used from the Country Code list.
13 Configuration ~ Telco Configuration Telco Configuration XAP TH2 Flow Screen The XAP TH2 Flow Screen shows a detailed block diagram of the audio path in relation to the TH2.There are four buttons on the Flow Screen: Dial,Telco Config, Telco Meters, and GPIO builder.The Flow Screen is displayed for the selected unit in the site panel on the left of the G-Ware screen. To configure the XAP TH2 1. Click the Telco Config button on the XAP TH2 Flow Screen. 2. The Telco Config window opens.
14 Configuration ~ Telco Configuration Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760
15 Configuration ~ Creating Custom Control Creating Custom Control To use GPIO Builder GPIO, or general purpose input/output, allows you to establish pin assignments for the XAP TH2's Control/Status port.These pins provide control via contact closure and status via open collector functions in the unit. 1. Open the GPIO Builder by clicking the GPIO Builder button on the Flow Screen. Figure 3.6. GPIO Builder in G-Ware 2. Select the Control/Status pin you want to program. 3.
16 Configuration ~ Synchronizing Site Files Synchronizing Site If you have created your site file offline, or have made changes to your site file, you will need to connect to your site and sync the units to the site file. To sync site file to the XAP TH2 If you sync to the Unit(s), you will update y o u r G-Ware site file with the state of the unit. If you sync to the Document, you will update your units with the configurations you have saved in the site file. ✍ 1.
CHAPTER 4: Operation The XAP TH2 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 TH2 unit and a telephone handset (optional) and with the Dial interface in G-Ware. You can also use touch panels and custom control devices. Using the XAP TH2 To answer a call Figure 4.1.
18 If you have enabled auto-answer, the XAP TH2 will connect to the call after one ring. ✍ Operation ~ Using the Dial 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 [F] will be lit), hang up when the conversation is complete. Using the Dial To make and disconnect a call 1. 2. 3.
Operation ~ Using the Dial Interface Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760 19
20 Operation ~ Controllers Controllers Custom control (DB-25) option A customer-supplied remote control or contact-closure switch can be programmed to perform functions such as: mute on/off, system on, and system off. For pinouts, see Remote connector pinout, page 26. External control system The XAP products are designed to function with external control systems.The controller is connected to the XAP 800 RS-232 port.
CHAPTER 5: Optimization Adjusting Levels In order to optimize the audio levels, you will need to place a call on the XAP TH2. This will enable you to evaluate the levels for caller audio, audio being sent to the telephone, dial tone, DTMF tone, audible hook indication, and audible ring indication. Adjusting receive audio To increase or decrease the caller audio level that is being sent to all sources (power amplifier, video codec, recording device, etc.
22 Optimization ~ Adjusting Levels Adjusting transmit audio To increase or decrease audio being sent to the telephone line, adjust the output gain on the XAP 800 output channel that is connected to the XAP TH2 Transmit Input. This will affect only the audio being sent to the telephone on that channel. See the XAP 800 manual or G-Ware help file for detailed instructions.
Optimization ~ Telco Meters Telco Meters Using meters Open the XAP TH2 Telco Meters window by clicking the Telco Meters button on the XAP TH2 Flow Screen.The Telco Meters window is a diagnostic tool which allows you to observe the performance of various aspects of XAP TH2 operation. Refer to the Transmit and Receive meters when making level adjustments. Figure 5.1.
24 Optimization ~ Telco meters levels.The range of the meter is -30 to +20dB. It is a peak meter and updates only when a signal is present. Total Telco Echo Reduction The Total Telco Echo Reduction meter is the sum of the TERL and TERLE meters. It indicates the total echo return loss in the system.The range of the meter is -50 to 0dB. It is a peak meter and only updates when signal is present. Transmit Input This meter shows the audio level input to the XAP TH2 for transmission to the telephone line.
