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 we t loca tions u nless the jack is s pec ifically designed fo r w et 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 le ak in the
vicinity of the leak.
5. Use only the power c or d , p owe r sup p ly, and /or
batteries indicated in the manual. Do not dispose
of batteries in a fire. They may explode. Check local codes for any s pec ial di sp osal i nst r ucti ons .
6. Never touch uninsulated tele phone wir es or te rminals unless the telephone line has been disconnected at the network interface.
7. Use caution when ins tallin g or modifyi ng t ele phone lines.

CANADIAN EQUIPMENT LIMITATIONS
Notice: The Canadian Industry and Science Canada label
identifies certified equipment. This certification means that
the equipment meets certain telecommunications ne twork
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
61203019L1-1 NT1 ACE User Manual xi
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 connection s
themselves, but should contact the appropriate electric inspection authority, or an electrician, as
appropriate.

NT1 ACE Overview
The ADTRAN NT1 ACE is a stand-alone unit, and is powered by an external power supply. The NT1 ACE can be
ordered with the power supply included (Part Number
1203019L1), or the power supply, Part Number 336048VUR2, can be ordered separately. The NT1 ACE can supply
power to TE attached through the S/T interface.

Chapter 2. Installation
Before Installing the NT1 ACE
After unpacking the NT1 ACE, 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 ACE for repair or for verification of damage during shipment.
Setting the Option Switches
Two option switches located on the side of the unit configure the Local Bus of the NT1 ACE, as shown in Figure 2-1.
LOCAL BUS
TERMINATIONCONFIGURATION
LONG
SHORT
Termination Switch
For reliable operation, the S/T bus must be properly terminated. In addition to the termination resistor provided in
the NT1 ACE, bus termination resistors can be provided in
the TE or externally. (See Table 2- 2 on page 9 for pin assignments.)

61203019L1-1 NT1 ACE User Manual 3
Installation
TE can provide termination resistor:
Enable 100 ohm termination resistor on one TE, and disable
the termination reistor on all other TE(s) attached to this bus.
If all of the unterminated TE(s) are within 20 feet of the NT1
ACE, set the NT1 ACE’s termination switch to 50. Otherwise, set the NT1 ACE’s termination switch to 100.
TE does not provide termination resistor:
In this case, an external terminating resistor must be used,
and the NT1 ACE’s termination switch should be set to
NONE.
Configuration Switch
The configuration switch is set according to how far away
the TEs are from the NT1 ACE.
When the configuration switch is set to SHORT, the maxi-
mum allowable distance between the NT1 ACE and the furthest TE is 600 feet, as shown in Figure 2-2.
When the configuration switch is set to LONG, the maxi-
mum allowable distance between the NT1 ACE and the furthest TE is 3000 feet, as shown in Figure 2-3.

Powering with the NT1 Power Supply
The ADTRAN NT1 Power Supply, part number 336048VUR2, provides up to 10 watts of power at -48 VDC. The
NT1 ACE requires 1.1 watts, leaving approximately 8.9
watts to power the TE(s). Before connecting any TE to be
powered from the NT1, verify that the total power requirement of the connected TE is less than 8.9 watts.
To connect the NT 1ACE to the NT1 Power Supply, perform
the following steps as illustrated in Figure 2-4.
1. Connect the Power Supply to the NT1 ACE at the
POWER jack located on the NT1 ACE.
2. Plug the Power Supply into the nearest wall outlet supplying 110 VAC, 60 HZ.
3. On the NT1 ACE, verify that the POWER and ERROR
indicators are illuminated. After approximately 15 seconds, the READY indicator sho uld flash at a 1 Hz ra te.
Should any of the indicators fail to operate as stated,
see the section
Troubleshooting

Installation
Connecting the Terminal Equipment
After successfully powering up the NT1 ACE, the POWER
and ERROR indicators should be on and the READY indicator should be flashing. Make sure that terminal equipment
(TE) is properly terminated as instructed in
Option Switches
on page 3. Plug the TE into one of the Local
Bus connectors at the rear of the unit. A second TE may be
plugged into the remaining Local Bus connector. If more
than two TEs need to be connected to the NT1 ACE, additional connections can be made in parallel to the S/T bus
using RJ-45 connectors.
TEs commonly have additional jacks wired in parallel.
These may be used to connect more than two TEs as provided for by the NT1 ACE. See the TE documentation for further information.
After the TE powers up, the ERROR indicator should go
out. There may be some delay between plugging in the TE
and the ERROR indicator going out, depending on the specific TE in use. If the ERROR indicator fails to go out, see the
section
Troubleshooting
on page 10.
As the ERROR indicator extinguishes, the READY indicator
should illuminate. The TE will now be ready to place and
receive calls. There may be a slight delay between the
appearance of the READY indicator and the TE’s ability to
place and receive calls, depending on the specific TE in use.
If the READY indicator fails to illuminate or if you are
unable to place or receive calls, see the section
on page 10.

Powering TEs from the NT1 ACE
The ADTRAN NT1 ACE can be used to provide power for
TEs connected to the S/T interface. The NT1 ACE supplies
power by a separate wire pair (PS2) on the two data jacks
marked S/T, as shown in Figure 2-1. The ADTRAN NT1
ACE SP, part number 1203019L3, also incorporates power
source 1 (PS1) which provides power over the transmit and
receive pairs. Before attempting to power any TE from the
NT1 ACE, verify that it can accept power from a PS1 or PS2
power source.
Table 2-1 gives network connector pin assignments, and
Table 2-2 provides guidelines for properly terminating the
local bus.
