CANADIAN EMISSIONS REQUIREMENTS
This digital apparatus does not exceed the Class B limits
for radio noise emissions from digital apparatus as set
out in the interference-causing equipment standard enti-
tled "Digital Apparatus," ICES-003 of the Department of
Communications.
Cet appareil numerique respecte les limites de bruits
radioelectriques applicables aux appareils numeriques
de Class B prescrites dans la norme sur le materiel brouil-
leur: "Appareils Numeriques," NMB-003 edictee par le
ministre des Communications.
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 permis-
sible to be connected to the facilities of the local telecom-
munications company. The equipment must also be
installed using an acceptable method of connection. In

61203019L1-1 NT1 ACE User Manual vii
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 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.

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 pre-
vent overloading. The termination on a loop may consist
of any combination of devices subject only to the require-
ment that the total of the Load Numbers of all devices
does not exceed 100.

Unit Overview
The ADTRAN NT1 ACE provides a basic rate interface
between customer ISDN terminal equipment (TE) and the
ISDN network (U). Figure 1 is an illustration of the NT1
ACE.
Figure 1. ADTRAN NT1 ACE
Two jacks are provided on the rear panel of the unit for this
purpose, as illustrated in Figure 2.
Figure 2. Interface Connectors
A single RJ-49C connector labeled NETWORK U connects
to the network. Two additional data jacks labeled S/T con-
nect to the local bus.

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.
LED Indicators
Table 1 describes the status of the LEDs located on the front
panel of the NT1 ACE.
Table 1. Status Indicators
If the 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 indicates a network problem. A slower
1 Hz rate indicates an S/T interface problem.

READY Green S/T- and U-interfaces ready to place call
ERROR Red S/T- or U-interface not ready
POWER Green Unit has power

61203019L1-1 NT1 ACE User Manual 3

If the 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. Terminal
equipment commanded tests produce a slower 1 Hz flash
rate.
Passive Bus Description
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.
Inspection
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.
