CANADIAN EMISSIONS REQUIREMENTS

This digital apparatus does not exceed the Class B limits for radio noise emis-

sions from digital apparatus as set out in the interference-causing equipment stan-

dard entitled "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

brouilleur: "Appareils Numeriques," NMB-003 edictee par le ministre des Com-

munications.

CANADIAN EQUIPMENT LIMITATIONS

Notice: The Canadian Industry and Science Canada label identifies certified equip-

ment. 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 com-

pany’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 main-

tenance facility designated by the supplier. Any repairs or alterations made by

the user to this equipment, or equipment malfunctions, may give the telecommu-

nications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connec-

tions of the power utility, telephone lines, and internal metallic water pipe sys-

tem, if present, are connected together. This precaution may be particularly

important in rural areas.

Users should not attempt to make such connections them-

selves, 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 of any combina-

tion of devices subject only to the requirement that the total of the Load Numbers

of all devices does not exceed 100.

1.0 GENERAL

1.01 Unit Overview

The ADTRAN NT1 Type 400 provides a basic rate interface be-

tween the customer’s ISDN Terminal Equipment (TE) and the

ISDN Network. Two interfaces areprovided for this purpose: con-

nection to the ISDN network is made by the “U” interface and

connection to the customer's ISDN TE is made by the S/T inter-

face.

The NT1 Type 400 is available in two configurations:

• The NT1 Type 400 Standalone with an internal power supply,

Part No. 1212.016L1.

• The NT1 Type 400 Circuit Pack, Part No. 1212.010.

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 by the customer. The NT1 Type 400 Circuit

Pack can also be purchased as a separate unit and mounted in a

Type 400 NCTE rack, as indicated in APPENDIX A.

LED Indicators

Table 1 describes the status of the LEDs located on the front panel

of the NT1 Type 400. There is a READY and ERROR indicator for

each port of the NT1 Type 400.

Table 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.
