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 entitled "Digital Apparatus," ICES-003
of the Department of Communications.
Cet appareil numerique respecte les limites de bruits radioelectriques

CANADIAN EQUIPMENT LIMITATIONS
Notice: The Canadian Industry and Science Canada label identifies cer-
tified 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 con-
nected to the facilities of the local telecommunications company. The
equipment must also be installed using an acceptable method of con-
nection. 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 situa-
tions.
Repairs to certified equipment should be made by an authorized Cana-
dian maintenance facility designated by the supplier. Any repairs or
alterations made by the user to this equipment, or equipment malfunc-
tions, 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,
butshouldcontacttheappropriate electricinspectionauthority,
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 require-
ment that the total of the Load Numbers of all devices does not exceed
100.

Chapter 1 About the NT1 Type 400
UNIT OVERVIEW
The ADTRAN NT1 Type 400 provides a basic rate interface between
the customer’s ISDN Terminal Equipment (TE) and the ISDN Net-
work. Two interfaces are provided for this purpose: connection to the
ISDN network is made by the “U” interface and connection to the cus-
tomer's ISDN TE is made by the S/T interface.
The NT1 Type 400 is available in two configurations:
• TheNT1Type400Standalonewith aninternalpowersupply,Part
No. 1212016L1.
• The NT1 Type 400 Circuit Pack, Part No. 1212010.
The ADTRAN NT1 Type 400 Standalone consists of two parts, a metal
housing containing the power supply, connectors, and the NT1 Type
400 Circuit Pack. The Circuit Pack can be removed from the housing
by removing the plastic front panel and sliding the unit out of the
housing. This allows access to the option switches which may be reset
bythecustomer. TheNT1Type400CircuitPackcan alsobe purchased
as a separate unit and mounted in a Type 400 NCTE rack, as indicated
in Appendix A, NT1 Type 400 Circuit Pack on page A-1.
LED Indicators
Table 1-1 on page 1-2 describes the status of the LEDs located on the
front panel of the NT1 Type 400. There are a READY and an ERROR
indicator for each port of the NT1 Type 400.

Chapter 1. About the NT1 Type 400
1-2 Nt1 T400 User Manual 61212016L1-20
Table 1-1. NT1 Type 400 Front Panel Indicators
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 rate (1 flash per second) indicates an S/T interface problem.
BASIC RATE DESCRIPTION
ISDN Basic Rate Service consists of two Bchannels at 64 kbps and a
single Dchannel at 16 kbps. Basic Rate Service (2B+D Service) pro-
vides a total of 144 kbps to the customer for the transport of voice, cir-
cuit switched data, and packet switched data. Each Bchannel can be
used forvoice or data.The Dchannel carries the signaling information
needed for call processing. The Dchannel can also carry packet
switched data using the X.25 protocol.
PASSIVE BUS DESCRIPTION
The S/T interface used to connectto the customer TE hasthe ability to
connectmultiple devices. This arrangement is referred to asthe passive
bus and can be used to connect up to eight TEs to the same Basic Rate
line, as described in Appendix B, S/T Bus Configurations on page B-1.

POWERING TEs FROM THE NT1
The ADTRAN NT1 Type 400 can be used to provide power for cus-
tomer TEs. If the NT1 T400 circuit pack is used, a total of 12 watts is
available. If the NT1 Type 400 Standalone unit is used, a total of seven
watts is available. This power can be provided by Power Source 1
(PS1), which provides power over the transmit and receive wire pairs
used by the S/T interface and requires no additional wire pairs; and
by Power Source 2 (PS2), which provides power over an additional
wire pair.
REAR PANEL
The NT1 Type 400 Standalone rear panel contains three RJ45 connec-
tors, as illustrated in Figure 1-1. A single connector, labeled NET-
WORK, is used to connect to the ISDN network. The remaining two
connectors, labeled CUSTOMER 1 and CUSTOMER 2, are used to in-
terface to the customer’s TEs. These connectors are wired in parallel,
and can be used to connect multiple TEs in a passive bus arrangement.

Chapter 2 Installation
After unpacking the unit, immediately inspect it for possible shipping
damage. If damage is discovered, file a claim immediately with the
carrier, then contact ADTRAN Customer and Product Service (CAPS)
Department at the number listed in the back page of the manual.
SETTING THE OPTION SWITCHES
Remove the Circuit Pack from the NT1 Standalone housing by remov-
ing the plastic front panel and sliding the Circuit Pack out of the front
of the unit. Figure 2-1 illustrates switch option locations; Table 2-1 on
page 2-2 lists the function of each switch.

Refer to Appendix B, S/T Bus Configurations on page B-1 to determine
what type of bus and termination apply to your installation to set the
switches accordingly.
POWERING UP THE NT1 TYPE 400 STANDALONE
To power-up the NT1 Type 400 Standalone for the first time, perform
the following procedures in order:
1. Plug the power cord into a grounded, 120 VAC, 60 Hz receptacle.
2. Verify that the ERROR indicators are illuminated. After about 15
seconds, the READY indicators should flash at a 1 Hz rate.
3. Should any of these indicators fail to operate as stated, see Chap-
ter 3, Troubleshooting on page 3-1.
Table 2-2 on page 2-3 gives pin assignments for the unit.
