FCC CLASS A NOTICE

WARNING: Changes or modifications to this unit not expressly approved by the party responsible for compliance could

void this user’s authority to operate this equipment.

NOTE: The ASX-200, the ASX-200WG, the ASX-200BX and the ASX-1000 have been tested and found to comply with the

limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable

protection against harmful interference when the equipment is operated in a commercial environment. This equipment

generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction

manual, may cause harmful interference to radio communications. Operation of the equipment in a residential area is

likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

DOC CLASS A NOTICE

This digital apparatus does not exceed Class A limits for radio noise emission for a digital device as set out in the Radio

Interference Regulations of the Canadian Department of Communications.

Le present appareil numerique n’emet pas de bruits radioelectriques depassant les limites applicables aux appareils nume-

riques de la class A prescrites dans le reglement sur le brouillage radioelectrique edicte par le ministere des Communica-

tions du Canada.

VCCI CLASS 1 NOTICE

This equipment is in the Class 1 category (Information Technology Equipment to be used in commercial and/or industrial

areas) and conforms to the standards set by the Voluntary Control Council For Interference by Information Technology

Equipment aimed at preventing radio interference in commercial and/or industrial areas.Consequently, when used in a

residential area or in an adjacent area thereto, radio interference may be caused to radios and TV receivers, etc. Read the

instructions for correct handling.

FCC REQUIREMENTS (Notice to Users of DS1 Service)

The following instructions are provided to ensure compliance with the Federal Communications Commission (FCC) Rules,

Part 68.

(1) This device must only be connected to the DS1 network connected behind an FCC Part 68

registered channel service unit. Direct connection is not allowed.

(2) Before connecting your unit, you must inform the telephone company of the following

information:

(3) If the unit appears to be malfunctioning, it should be disconnected from the telephone lines

until you learn if your equipment or the telephone line is the source of the trouble. If your

equipment needs repair, it should not be reconnected until it is repaired.

(4) If the telephone company finds that this equipment is exceeding tolerable parameters, the

telephone company can temporarily disconnect service, although they will attempt to give

you advance notice if possible.

(5) Under the FCC Rules, no customer is authorized to repair this equipment. This restriction

applies regardless of whether the equipment is in or out of warranty.

(6) If the telephone company alters their equipment in a manner that will affect use of this

device, they must give you advance warning so as to give you the opportunity for uninter-

rupted service. You will be advised of your right to file a complaint with the FCC.

CANADIAN IC CS-03 COMPLIANCE STATEMENT

NOTICE: The Industry Canada label identifies certified equipment. This certification means that the equipment meets cer-

tain telecommunications network protective, operational and safety requirements. The Industry Canada label does not

guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local tele-

communications company. The equipment must also be installed using an acceptable method of connection. In some cases,

the company’s inside wiring associated with a single line individual service may be extended by means of a certified con-

nector assembly (telephone extension cord). The customer should be aware that 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 telecommunica-

tions 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.

Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric

inspection authority, or electrician, as appropriate.

E1 AND E3 NOTICE

The E1 (NM-6/E1C and NM-2/E1C) and E3 (NM-4/E3C and NM-2/E3C) network modules that are described in this

manual are approved for use in FORE Systems’ host systems providing that the instructions below are strictly observed.

Failure to follow these instructions invalidates the approval.

Pan European Approval - CE Marking

Pan European approval of the E1 network module was issued by BABT following assessment against CTR12. This means

that it can be connected to ONP and unstructured PTO-provided private circuits with 120 Ω interfaces in all European

countries, according to Telecommunications Terminal Equipment (TTE) Directive 91/263/EEC. Thus, the following CE

mark applies:

The E1 and E3 network modules conform to safety standard EN60950 1992 following the provisions of Low Voltage

Product Safety Directive 73/23/EEC and CE Marking Directive 93/68/EEC, and can be marked accordingly with the CE

symbol.

The E1 and E3 network modules conform to EN55022 1994 and EN50082-1 1992 following the provisions of the EMC

Directive 89/336/EEC, and can be marked accordingly with the CE symbol.

Required User Guide Statements - UK Installation

The use of auxiliary products not authorized by FORE Systems in FORE Systems ATM Switches may cause the power spec-

ification to be exceeded and is a potential safety hazard.

The equipment must be installed such that with the exception of the connections to the host, clearance and creepage

distances shown in the table below are maintained between the network module and any other assemblies which use or

generate a voltage shown in the table below. The larger distance shown in brackets applies where the local environment

within the host is subject to conductive pollution or dry non-conductive pollution which could become conductive due to

condensation. Failure to maintain these minimum distances invalidates the approval.

NOTE: Installing the network modules in the appropriate FORE Systems hosts, according to the installation instructions

provided, satisfies the requirements listed above.
