Introduction
Congratulations
INTRODUCTION •
1
Congratulations on purchasing the XAP TH1 telephone interface. The
XAP TH1 uses the latest digital technology to maintain the highest
possible audio quality. The XAP TH1 is designed to function as a standalone product or as an accessory to the XAP 800 (echo cancelling,
audio processing, microphone mixing matrix) to add telephone lines
into audioconferences.
The XAP TH1 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.
This manual explains how to install, set up and operate the XAP TH1 in a
step-by-step format. It also supplies instructions on how to resolve
technical problems, should any arise.

INTRODUCTION • CONTROLS AND CONNECTIONS
Front View
The XAP TH1 front-panel controls (see Figure 2, above) perform the
following functions:
1. Transmit LED This bicolor LED indicates the audio levels being
transmitted from the room to the telephone line.
2. Receive LED This bicolor LED indicates the audio level the room is
receiving from the telephone line.
3. On LED This bicolor LED indicates the hybrid’s ON state. The LED
will illuminate green when the hybrid is in the ON state.
4. Off LED This bicolor LED indicates the hybrid’s OFF state. The LED
will illuminate red when the hybrid is in the OFF state.
5. On The ON button (momentary) connects the hybrid to the
telephone line (dependent upon DIP switch settings) and
automatically adapts the hybrid to the line. Pressing and holding
the ON button for more than a half-second while the hybrid is active
will readapt the hybrid.
6. Off The OFF switch (momentary) disconnects the hybrid from the
telephone line and mutes all audio.
Rear View
The XAP TH1 back-panel connectors (see Figure 3, above) perform the
following functions:
1. Power The AC power cord input is a NEMA type connector allowing
100–240VAC, 50/60Hz.

INTRODUCTION
• CONTROLS AND CONNECTIONS
2. RS-232 This female DB9 serial port provides connection between
the XAP TH1 and a PC or custom remote control.
3. Remote This DB25 connector provides control and status of the
XAP TH1. See Appendix B for pinouts.
4. Transmit Input This Phoenix™ connection provides a non-gated
electronically balanced line level input. The nominal input level is 0
dBu. This line input is mutable. The default setting is off (not muted).
5. Receive Output This Phoenix connection provides a balanced line
level output. The nominal output level is 0 dBm. The outputs adjust
for line imbalances and maintain a constant output level. This line
output is mutable. The default setting is off (not muted).
6. Line This RJ-11 connector provides connection of a standard
analog telephone line to the hybrid.
7. Set This RJ-11 connector allows connection to a standard telephone
set. Tip and ring from the phone line are present at this connector
when the hybrid is in its Off state. Tip and ring from the phone line
are not present at this point when the hybrid is in its On state.
Touch-Tone Dialing
Through the RS-232 (and serial commands), the XAP TH1’s touch-tone
(DTMF) dialing capability can be accessed. This allows outbound calls to
be initiated by the XAP TH1 without requiring an external dialer or
telephone set. This feature continues to function after connection,
enabling the user to issue tones for voice mail/pager interaction. See
Serial Commands on page 15.

INTRODUCTION • BEFORE YOU INSTALL
Power Requirements
The XAP TH1 automatically accommodates voltage requirements of
100–240VAC, 50/60Hz, 15W.
Telephone Line Requirements
The XAP TH1 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 XAP
TH1, call your telephone company for installation.
Equipment Placement
The XAP TH1 models are designed for installation into a standard 19inch equipment rack. You can also purchase side panels for desktop
placement.
