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 users satisfaction.  
Before installing this equipment, ensure that it is permis-  
sible to be connected to the facilities of the local telecom-

some cases, the companys 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 situa-  
tions.  
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, tele-  
phone 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 author-  
ity, or an electrician, as appropriate.

IMPO RTAN T SAFETY IN STRUCTIO N S  
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 exam-  
ple, near a bath tub, wash bowl, kitchen sink  
or laundry tub, in a wet basement or near a  
swimming pool).  
2. Avoid using a telephone (other than a cordless  
type) during an electrical storm. There may be  
a remote risk of electric shock from lightning.  
3. Do not use the telephone to report a gas leak in  
the vicinity of the leak.  
4. Use only the power cord, power supply, and/  
or batteries indicated in the manual. Do not  
dispose of batteries in a fire. They may ex-  
plode. Check local codes for any special dis-  
posal instructions.

The U-interface complies with ANSI T1.601 and  
ITU-TI.430 Recommendation Standard. The S/T-interface  
complies with ANSI T1.605 and ETSI ETS 300012 Stan-  
dard.  
The ADTRAN NT1 ACE is a stand-alone unit. An external  
power source must be provided for the NT1 ACE. External  
power is supplied by the ADTRAN Power Supply, part  
number 336048VUR-2. The two S/ T bus connectors on the  
rear of the unit enable the NT1 ACE to supply power to the  
TE.

command tests cause a faster 8 Hz flash rate. Terminal  
equipment commanded tests produce a slower 1 Hz flash  
rate.

The Local Bus interface may be used to connect up to eight  
TEs to the NT1 ACE. This arrangement is referred to as a  
Passive Bus. See the section Short Passive Bus Configuration  
on page 9 for detailed information.  
In sp e ctio n  
After unpacking the unit, immediately inspect it for possi-  
ble shipping damage. If damage is discovered, file a claim  
immediately with the carrier; then contact ADTRAN Cus-  
tomer Service. If possible, keep the original shipping con-  
tainer for use in shipping the NT1 ACE for repair or for  
verification of damage during shipment.  
Never install telephone wiring during a lightning  
storm.  
Never install telephone jacks in wet locations unless  
the jack is specifically designed for wet locations.  
Never touch uninsulated telephone wires or termi-  
nals unless the telephone line has been disconnect-  
ed at the network interface.  
Use caution when installing or modifying tele-  
phone lines.

Ma in te n a n ce  
The ADTRAN NT1 ACE requires no routine maintenance to  
operate. In case of equipment malfunction, refer to the sec-  
tions Remote Testing and Repair and Return or remove the unit  
and replace it with another unit optioned in an identical  
manner.  
Re m o te Te stin g  
Network test features include a loopback test initiated at the  
central office. This test confirms network integrity to the  
NT1 ACE.  
Re p a ir a n d Re tu rn  
Repairs should not be performed in the field. Repair services  
can be obtained by returning the unit to the ADTRAN Cus-  
tomer and Product Service (CAPS) Department at the  
address listed on the inside back cover of this manual.

Powering TEs from the NT1 ACE on page 6 for more informa-  
tion concerning Local Bus configurations.  
The switch labeled CONFIGURATION has two possible  
options. When set in the LONG position, the Local Bus is  
configured for Extended Passive Bus. When set in the  
SHORT position, the Local Bus is configured for Short Pas-  
sive Bus. Configuration and switch settings are discussed in  
Short Passive Bus Configuration on page 9 and in Extended  
Passive Bus Configuration on page 10.  
The Power Supply provides up to 10 watts of power for the

Po w e rin g TEs fro m th e N T1 ACE  
The ADTRAN NT1 ACE can be used to provide power for  
TEs connected to the local interface. The NT1 ACE, part  
number 1203019L1, supplies power by a separate wire pair  
(PS2) on the two data jacks marked LOCAL, as shown in  
Figure 2 on page 1. The ADTRAN NT1 ACE International,  
part number 1203019L3, also incorporates power source 1  
(PS1) which provides power over the transmit and receive  
pairs. Table 3 lists Local Bus connector pin assignments.  
Before attempting to power any TE from the NT1 ACE, ver-  
ify that it can accept power from a PS1 or PS2 power source.

The ADTRAN NT1 Power Supply, part number 336048VUR-

NT1 ACE requires 1.1 watts, leaving approximately 8.9  
watts to power the TE(s). Before connecting any TE to be  
6

NT1 ACE User Manual  
powered from the NT1, verify that the total power require-  
ment of the connected TE is less than 8.9 watts.  
To connect the NT1 ACE to the NT1 Power Supply, perform  
the following steps as illustrated in Figure 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 should flash at a 1 Hz  
rate. Should any of the indicators fail to operate as  
stated, see the section Troubleshooting on page 11.

After successfully powering up the NT1 ACE, the POWER  
and ERROR indicators should be on and the READY indica-  
tor should be flashing. Make sure that terminal equipment  
(TE) is properly terminated as instructed in Setting the  
Option Switches on page 4. 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, addi-  
tional 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 provid-  
ed for by the NT1 ACE. See the TE documentation for fur-  
ther 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 sec-  
tion Troubleshooting on page 11.  
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 TEs 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 Troubleshoot-  
ing on page 11.

one of the TEs connected should be terminated with 100
