Introduction
Congratulations
INTRODUCTION • 1
Congratulations on purchasing the XA TH2 telephone interface. The
XA TH2 is a single-line digital hybrid which uses digital signal
processing (DS ) 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.
The XA TH2 is designed to function as a standalone telephone hybrid
or as an accessory to the XA 800 (echo cancelling, audio processing,
microphone mixing matrix), enabling you to add remote callers to your
audioconferences.
This manual explains how to install, configure, and operate the XA TH2
in a step-by-step format.

INSTALLATION • HARDWARE SETU 9
Assign Device ID Numbers
Before creating an Expansion Bus network, you need to set up unique
Expansion Bus Device ID numbers for each XA TH2 on the network.
There are 16 Expansion Bus network device locations that can be
selected (0-F). As shipped from the factory, all XA TH2 units default as
binary address 0.
Set Device ID numbers for each XA TH2 unit at your site by
manipulating rear-panel DI switches 1–4 [5], selecting/deselecting
each switch to set up address 0–15 in binary code. The table below
illustrates DI switch settings. DI switch changes are only read when
the unit is powered up so you will need to power cycle the unit to have
the changes recognized.

Create an Expansion Bus Network
1. lace the XA TH2 unit in the rack. The back-panel Expansion Bus
In and Expansion Bus Out connectors are designed for setting
up your Expansion Bus network. Connections between units are
made in daisy-chain fashion using category five twisted-pair cable.
2. The first XA unit in the chain must have the Expansion Bus In
connector terminated with an Expansion Bus terminator (provided).
3. The first XA unit’s Expansion Bus Out connector is then attached
to the Expansion Bus In connector on the next unit in the chain. At
the end of the network, the final unit must have the Expansion Bus
Out connector terminated with an Expansion Bus terminator as well.
An Expansion Bus network will allow interconnection of up to16
XA TH2s and any combination of XA 800s and SR1212s where the
number of microphone inputs does not exceed 64.
Connecting Power
The power input [1] will operate at any level between 100–240VAC,
50–60Hz, 15W (typical). lug in the XA TH2 to complete the hardware
installation.
If networked XAP 800s and
TH2s are stacked vertically,
connect them sing the
short RJ-45 j mper. When network-
ing between long distances, se
category five twisted-pair (10BaseT
LAN) cable. The maxim m cable
r n between XAP 800 and PSR1212
nits is 80 feet (24 meters).

2. If you have already establish 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 DI
switches. Device IDs ensure the software will sync up with the
proper unit when there are multiple TH2s on a network.
3. Adjust the Meter Refresh rate as necessary. The default rate is 50.
4. Select the country where this product is being used from the
Co ntry Code list.
Warning: The co ntry code m st be set correctly to ens re that
the nit operates properly when connected to the telco network

this code to a co ntry other than the intended co ntry of
operation might ca se the XAP TH2 to be non-compliant.
5. Click the Comm tab to select the Serial Echo and Serial Mode
you want to use.
Serial Echo enables the unit to echo back the commands you send
over the E-Bus network. Serial Mode determines the format (binary
or text) in which the commands return over the E-Bus network. The
default setting when G-Ware is connected to a unit is binary. When
the unit is disconnected, the default is text.
6. Select Use Modem if a modem will be used with the unit.
7. Click the Sec rity tab to enter a Modem Password. This

14 CONFIGURING G-WARE • ADDING A XA TH2
Feat re Description
Receive Red ction This feature lowers receive audio coming in through the telephone line when transmit audio is
present. This feature is typically used in applications where the transmit party needs control of
the conversation. When activated, the receive audio is ducked by 6dB. Receive Reduction can
be turned on or off. The default is off.
A to Answer The XA TH2 can be programmed to answer after one complete valid ring has been detected.
The unit connects to the line automatically in the same manner it would connect if the you
issued a connect command. Auto Answer can be turned on or off. The default is off.
Receive ALC Automatic Level Control (ALC) may be selected on the telco input. This feature is designed to
keep soft and loud telephone participants at a consistent level. The parameters of ALC are not
user adjustable. ALC can be turned on or off. The default setting is on.
Edit Speed Dial The XA TH2 supports 10 speed dial numbers. Each number can be 40 digits long and can
have a 20 character label associated with it. These numbers and labels are stored in non-
volatile memory and the number can be called by a single command. Any valid touch-tone digit
and the pause character (comma) may be stored. All speed dial numbers are empty except for
number 9 which is programmed with Gentner's technical support number 10 which is
programmed with the conference calling services number.
Hook Flash D ration Hook Flash is supported by a single command. When the command is received, the unit will
execute a flash for the duration programmed. Variable length Hook Flash is programmable on
the unit. The on/off time is programmable from 50msec to 2 seconds in 10msec steps. The
default is 250msec.
Telco Adaptation In some applications, it may be desirable to adapt the hybrid with a white-noise burst rather
than allowing the hybrid to adapt automatically to line conditions. This feature allows you to
choose between Noise Burst and Auto Adapt. The default is Auto Adapt.
Receive Boost The Receive Boost adds 6dB of gain to the receive signal delivered from the phone line. This is
typically used for low-level telephone lines allowing the signal to be boosted into a range where
the hybrid can perform at an adequate level of acceptance. The Receive Boost can be turned
on or off. The default is off. This feature is setup during the initial configuration and is not used
to adjust level from call to call.
A to Disconnect The XA TH2 supports automatic disconnection of calls either from loop drop or from call
progress tone detection. Auto Disconnect can be turned on (Loop + Call rogression, Call
rogression, Loop) or off. The default is Loop which is on.
Loop Drop + Call Progression If either a call progress tone or loop drop/reversal is detected, the unit will perform a normal
disconnect.
Call Progression If a call progress tone is detected, the unit will perform a nomal disconnect.
Loop When a valid loop drop or reversal is detected, the unit will perform a normal disconnect. This is
the default state.
DTMF Level This feature allows you to adjust the DTMF tone level in relationship to the participant audio
level in the room. The level can be adjusted in 1dB steps from a nominal level 0 (default) to plus
or minus 12dB.
Dial Tone Level This feature allows you to adjust the Dial Tone level in relationship to the participant audio level
in the room. The level can be adjusted in 1dB steps from a nominal level 0 (default) to plus or
minus 12dB.
A dible Hook Indication When the unit goes off hook (connects) a beep is injected into the receive channel and
transmit channel of the unit. When the unit goes on hook (disconnects), a series of 2 beeps is
injected into the receive channel to indicate that the call has been dropped. This indicator can
be turned on and off by selecting and deselecting the checkbox. The default is on. The level
adjustment allows you to customize the level in relationship to the participant audio levle in the
room. the level can be adjusted in 1dB steps from a nominal level 0 (default) to plus or minus
12dB
A dible Ring In the On mode, when a valid ring is detected the front panel LED flashes, a serial command is
transmitted , and an audible ring is heard from the receive channel. In the Off mode, the front
panel LED flashes and a serial command is transmitted, however, no ring tone is generated.
This indicator can be turned on and off by selecting and deselecting the checkbox. The default
is on. The level adjustment allows you to customize the level in relationship to the participant
audio levle in the room. the level can be adjusted in 1dB steps from a nominal level 0 (default)
to plus or minus 12dB.
