IMPORTANT SAFETY INSTRUCTIONS
When using your telephone equipment, basic safety precautions should always be followed to reduce the risk of
fire, electric shock and injury to persons. The precautions
are listed below.
1. Do not use this product near water (for example, near a bath tub, wash bowl, kitchen sink or
laundry tub, in a wet basement or near a swimming pool).
2. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
3. Avoid using a telephone (other than a cordless
type) during an electrical storm. There may be a
remote risk of electric shock from lightning.
4. Do not use the telephone to report a gas leak in the
vicinity of the leak.
5. Use only the power cord, power supply, and/or
batteries indicated in the manual. Do not dispose
of batteries in a fire. They may explode. Check local codes for any special disposal instructions.
6. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
7. Use caution when installing or modifying telephone lines.
SAVE THESE INSTRUCTIONS.

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 voiceband 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 to a 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
Notice: The Canadian Industry and Science Canada
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, 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). 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 water pipe 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

NT1 ACE4 User Manual
The U interface complies with ANSI T1.601 and ITUT1.430 Recommendation Standard. The S/T interface complies with ANSI T1.605 and ETSI ETS 300012 Standard.
The ADTRAN NT1 ACE4 is a stand-alone unit and is powered by an external power supply (the ADTRAN power
supply, part number 336012VUR01).
LED Indicators
Table 1-1 describes the status of the LEDs located on the
front panel of the NT1 ACE4. There is a READY and
ERROR indicator for each port of the NT1 ACE4.

Description
READY
Green

ERROR
Red

If an ERROR indicator is illuminated, check the flash rate of
the READY indicator to determine the source of the error. A
faster 8 Hz flash rate (8 flashes per second) indicates a network problem. A slower 1 Hz flash rate (1 flash per second)
indicates an S/T interface problem.

NT1 ACE4 User Manual
61200242L1-1

If an ERROR indicator is not illuminated and the READY
indicator is flashing, a network test is in progress. Network
command tests cause a faster 8 Hz flash rate.
Inspection
After unpacking the NT1 ACE4, carefully inspect it for shipping damage. If damage is suspected, file a claim immediately with the carrier and contact ADTRAN Technical
Support. If possible, keep the original shipping container
for use in shipping the NT1 ACE4 for repair or for verification of damage during shipment.
Maintenance
The NT1 ACE4 requires no routine maintenance to operate.
In case of equipment malfunction, refer to the sections
Remote Testing and Repair and Return below or remove the
unit and replace it with another unit optioned in an identical manner.
Remote Testing
Network test features include a loopback test initiated at the
central office. This test confirms network integrity to the
NT1 ACE4.
Repair and Return
Repairs should not be performed in the field. Repair services can be obtained by returning the unit to the ADTRAN

Powering with the NT1 ACE4 Power Supply
The ADTRAN NT1 ACE4 Power Supply, part number
336012VUR01, provides power to the NT1 ACE4 . To connect
the NT1 ACE4 to the external power supply, perform the following steps (see Figure 1-5).
1. Connect the power supply to the NT1 ACE4 at the
POWER jack located on the NT1 ACE4 rear panel.
2. Plug the power supply into the nearest wall outlet supplying 120 VAC, 60 Hz.
3. On the NT1 ACE4, verify that the ERROR indicators
are illuminated. After approximately 15 seconds, the
READY indicators should flash at a 1 Hz rate. Should
any of the indicators fail to operate as stated, see the
section Troubleshooting on page 8.

Connecting the Terminal Equipment
After successfully powering up the NT1 ACE4, the ERROR
indicators should be on and the READY indicators should
be flashing. Make sure that terminal equipment (TE) is
properly terminated. Plug the TE into one of the S/T connectors at the rear of the unit.
The ERROR indicators should extinguish a few seconds
after power is applied to the TE. If the ERROR indicators
fail to go out, see the section Troubleshooting on page 8.
As the ERROR indicators extinguish, the READY indicators should illuminate. There may be a slight delay between
the appearance of the READY indicators and the TE’s ability to place and receive calls, depending on the specific TE
in use. If the READY indicators fail to illuminate or if you
are unable to place or receive calls, see the section Troubleshooting on page 8.
Typical Configuration
This configuration allows you to connect up to four TEs at
ranges up to 3000 feet from the NT1 ACE4, as shown in Figure 1-6. A termination resistor should be centrally located to
the TEs. The NT1 ACE4 TERMINATION is set to 100 ohms.
The TEs should be set to 100 ohms.
