Telephone Access System Programming Manual

55 (60)

Repairs to certified equipment should be made by an authorized Canadian maintenance facility

designated by the supplier. Any repairs or alteration 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 earth ground connections of the power

utility, telephone lines and internal metallic water pipe system, if present, are connected together. This

is necessary both for proper operation and for protection.

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

appropriate electric inspection authority, or electrician, as appropriate.

Note: The Ringer Equivalence Number (REN) assigned to each terminal device provides an

indication of the maximum number of terminals allowed to be connected to a telephone

interface. The termination on an interface may consist of any combination of devices

subject only to the requirement that the sum of the RENs of all the devices does not exceed

five.

Type of Service

The TX3 is designed to be used on standard device telephone lines. It connects to the telephone line by

means of a standard jack called the USOC RJ-11C (or USOC FJ45S). Connection to telephone

company-provided coin service (central office implemented systems) is prohibited. Connection to

party lines service is subject to state tariffs.

Telephone Company Procedures

The goal of the telephone company is to provide you with the best service it can. In order to do this, it

may occasionally be necessary for them to make changes in their equipment, operations or procedures.

If these changes might affect your service or the operation of your equipment, the telephone company

will give you notice, in writing, to allow you to make any changes necessary to maintain uninterrupted

service.

In certain circumstances, it may be necessary for the telephone company to request information from

you concerning the equipment which you have connected to your telephone line. Upon request of the

telephone company, provide the FCC registration number and the ringer equivalence number (REN);

both of these items are listed on the equipment label. The sum of all of the RENs on your telephone lines

should be less than five in order to assure proper service from the telephone company. In some cases, a

sum of five may not be useable on a given line.
