equipment 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.
Operation of this equipment 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 expense.

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.

INFORMATION

FCC regulations require that the following information be provided to the customer in this manual:

1. This equipment complies with Part 68 of the FCC rules. The required label is affixed to
the bottom of the chassis.

2. If your telephone equipment (FXO+) causes harm to the telephone network, the
telephone company may discontinue your service temporarily. If possible, they will notify
you in advance. But if advance notice is not practical, you will be notified as soon as
possible. You will be advised of your right to file a complaint with the FCC.

3. Your telephone company may make changes in its facilities, equipment, operations, or
procedures that could affect the proper operation of your equipment. If they do, you will
be given advance notice so as to give you an opportunity to maintain uninterrupted
service.

4. If you experience trouble with this equipment (FXO+), please contact ADTRAN Customer
Service for repair/warranty information (see the end of this manual). The telephone
company may ask you to disconnect this equipment from the network until the problem
has been corrected or until you are sure the equipment is not malfunctioning.

5. This unit contains no user serviceable parts.

6. The following information may be required when applying to your local telephone
company for switched line facilities:

Service REN/SOC FIC USOC

Loop Start 0.3B/9.0F 02LS2 RJ11C
Ground Start 0.1A/9.0F 02GS2 RJ11C

7. The REN and FCC registration number are indicated on the label. The ringer equivalence
number (REN) is used to determine how many devices can be connected to your telephone
line. In most areas, the sum of the RENs of all devices on any one line should not exceed
five (5.0). If too many devices are attached, they may not ring properly.

8. On the circuit board of this equipment is a label that contains, along with other informa­tion, the FCC registration number and ringer equivalence number (REN) for the equip­ment requested. Provide this information to your telephone company.

9. The equipment may not be used on public coin service provided by the telephone
company. Connection to party lines is subject to state tariffs.

AFFIDAVIT REQUIREMENTS FOR CONNECTION TO DIGITAL SERVICES

• An affidavit is required to be given to the telephone company when­ever digital terminal equipment without encoded analog content and
billing protection is used to transmit digital signals containing encoded
analog content which are intended for eventual conversion into voice
band analog signals and transmitted on the network.

• The affidavit shall affirm that either no encoded analog content or
billing information is being transmitted or that the output of the device
meets Part 68 encoded analog content or billing protection specifica­tions.

• End user/customer will be responsible to file an affidavit with the local
exchange carrier when connecting unprotected CPE toa 1.544 Mbps or
subrate digital services.

• Until such time as subrate digital terminal equipment is registered for
voice applications, the affidavit requirement for subrate services is
waived.

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 Department does not guarantee
the equipment will operate to the user's satisfaction.

Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equipment
must also be installed using an acceptable method of connection. In some cases, the
company's inside wiring associated with a single line individual service may be
extended by means of a certified connector assembly (telephone extension cord). The
customer should be aware that compliance with the above conditions may not
prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian mainte­nance facility designated by the supplier. Any repairs or alterations made by the user
to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections
of the power utility, telephone lines and internal metallic waterpipe system, if
present, are connected together. This precaution may be particularly important in
rural areas.

Users should not attempt to make such connections themselves,
but should contact the appropriate electric inspection author­ity, or an electrician, as appropriate.

The Load Number (LN) assigned to each terminal device denotes the percentage of
the total load to be connected to a telephone loop which is used by the device, to
prevent overloading. The termination on a loop may consist of any combination of
devices subject only to the equipment that the total of the LNs of all devices does not
exceed 100.

The ringer equivalence number (REN) assigned to each terminal adapter 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.

FXO+ DUAL VOICE OVERVIEW

The FXO+ Dual Voice (FXO+) option module is one of
the option modules available for use with the
ADTRAN 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 ADTRAN 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

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 follow­ing 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
