RADIO FREQUENCY INTERFERENCE STATEMENT:
This equi ment has been tested and found to com ly with the limits for a Class A digital device,
ursuant to Part 15 of the FCC Rules. These limits are designed to rovide reasonable rotection
against harmful interference when the equi ment is o erated in a commercial environment. This
equi ment generates, uses, and can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful interference to radio frequencies.
O eration of this equi ment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own ex ense.
Shielded cables must be used with this unit to ensure compliance with Class A FCC limits.
Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.

CANADIAN EQUIPMENT LIMITATIONS
The Industry Canada Certification label identifies certified
equipment. This certification means that the equipment meets
certain telecommunications network protective, operational,
and safety requirements. The epartment does not guarantee
the equipment will operate to the user's satisfaction.
Before installing this equi ment, users should ensure that it is ermissible to be
connected to the facilities of the local telecommunications com any. The equi ment
must also be installed using an acce table method of connection. In some cases, the
com any's inside wiring associated with a single line individual service may be
extended by means of a certified connector assembly (tele hone extension cord). The
customer should be aware that com liance with the above conditions may not
revent degradation of service in some situations.
Re airs to certified equi ment should be made by an authorized Canadian mainte-
nance facility designated by the su lier. Any re airs or alterations made by the user
to this equi ment, or equi ment malfunctions, may give the telecommunications
com any cause to request the user to disconnect the equi ment.
Users should ensure for their own rotection that the electrical ground connections
of the ower utility, tele hone lines and internal metallic water i e system, if
resent, are connected together. This recaution may be articularly im ortant in
rural areas.
Users should not attempt to make such connections themselves,
but should contact the appropriate electric inspection author-
ity, or an electrician, as appropriate.
The Load Number (LN) assigned to each terminal device denotes the ercentage of
the total load to be connected to a tele hone loo which is used by the device, to
revent overloading. The termination on a loo may consist of any combination of
devices subject only to the equi ment that the total of the LNs of all devices does not
exceed 100.
The ringer equivalence number (REN) assigned to each terminal ada ter is used to
determine the total number of devices that may be connected to each circuit. The sum
of the RENs from all devices in the circuit should not exceed a total of 5.0.

Introduction
FXO+ DUAL VOICE OVERVIEW
The FXO+ Dual Voice (FXO+) option module is one of
the option modules available for use with the
ADTRA TSU 100/120/600. The FXO+ module
provides two 2-wire voice-grade interfaces serving as
the loop termination for central office line current and
ringing voltage.
The FXO+ module emulates a telephone or station
interface. It responds to signaling from the digital
signal, level 1 (DS1) stream by providing loop closure
or ring ground to the 2-wire interface. The condition
of tip-ground and ringing on the 2-wire interface is
converted to signaling out the DS1 stream. The FXO+
may serve as the office side of a foreign exchange
FXO/FXS application. The FXO+ may be used with
the ADTRA FXS+ to implement message-waiting
with analog message-waiting phones that need -150
VDC to light the message lamp. The FXO+ module
features on-hook data transmission for passing Caller
ID data from the 2-wire interface to the DS1 stream.
When the FXO+ is used in the dial pulse terminate
(DPT) mode with E&M signaling on the DS1 stream, it
extends the central office side of an analog direct
inward dial (DID) trunk to the customer premises.
The FXO+ may be used to connect to the station side
of a private branch exchange (PBX). Signaling and
interfaces comply with portions of EIA/TIA-464-A

Chapter 1. Introduction
2FXO+ Dual Voice Option Module User Manual 61200.103L2-1
and AT&T Pub. 43801, and FCC Part 68. The FXO+
option module also accepts the FXO+ plug-on board to
provide up to four FXO+ functional ports per option
slot used, as well as accepting other plug-on modules.
The FXO+ plug-on module may be plugged onto any
existing TSU option module.
Functional Description
The FXO+ is designed to fit in the option slot of the
TSU 100/120/600 and is subject to its operation and
control. The FXO+ is configured from the front panel
of the TSU 100/120/600 or by an external personal
computer (PC) program (T-Watch). The internal
menus for its configuration are a part of the FXO+
module and are automatically installed when the
FXO+ is plugged into the unit.
Features
The FXO+ Dual Voice option module has the follow-
ing features:
• Each 2-wire port operates at 64 kbps
• Menu configurable transmit (TX) and receive (RX)
levels (transmit level points - TLPs)
• FXO, FXO message waiting, and DPT operating
modes
• Passes Caller ID data from the 2-wire interface to the
T1
• Ground Start or Loop Start 2-Wire Supervision
• Extensive testing capabilities:
- RX and TX signal bit monitoring
- Busy, ringing, message-waiting, and status
monitoring
- Integral 1 kHz tone generation sends test tone
towards near or far end
- Manual control of TX A and B signal bits
- Manual control of 2-wire interface supervision
output
• Adding the FXO+ plug-on board provides the TSU

The FXO+ is an option module which plugs into the
option slot in the rear of the main unit; see Figure 1-1.
PORT X.3
DUAL FXO
PORT X.1 PORT X.2
Figure 1-1
FXO+ Dual Voice Option Module
The FXO+ rear panel includes a plastic plug over a
cutout for additional connectors. This allows a plug-
on board to be added to the FXO+ module. The PORT
X.Y indication is linked to the port numbering philoso-
phy of the TSU 100 product family. The X represents
the slot number, and the .Y indicates the port
number. For the TSU 100 application, there is only
one option slot. Therefore the port designations for
the two FXO voice ports will be 1.1 and 1.2. If added,
the plug-on board port designation would be 1.3 and
1.4. These port numbers appear in the front panel
liquid crystal display (LCD) menu displays.

INSTALLING THE FXO+ DUAL VOICE OPTION MODULE
For ease of replacement, power to the SU 100/120/
600 may be on when installing or removing the FXO+
Dual Voice option module.
For use in Canada, regulatory compliance requires that the
Transmit Level/Transmit Level Point, TX LVL (TLP), o the
FXO+ Dual Voice option module be set to a value between
+3dB and +8dB inclusive, and that the TSU 100/120/600
be password protected to prevent unauthorized alteration o
the level.
See the chapter Operations or in ormation on setting the
Transmit Level/Transmit Level Point, TX LVL (TLP). See
the TSU 100/120/600 user manual or in ormation about
password protecting the unit.
