FCC regulations and telephone company procedures prohibit connection of 
customer-provided equipment to telephone company-provided coin service (central 
office-implemented systems). Connection to party lines is subject to state tariffs.

Occasionally, the telephone company may make changes in their equipment, 
operations, or procedures. If these changes affect your equipment or service, the 
telephone company will provide written notice so you can make the necessary 
changes to maintain uninterrupted service.

Contact your telephone company if you have any questions about your telephone 
line.

In some circumstances, the telephone company may ask you for information about 
your equipment that is connected to the telephone line. Within the United States (at 
the request of the telephone company), you should provide your equipment’s FCC 
registration number. This number is located on the unit’s label.

Before the 6500

 DSU option can be connected to the network, the local 

operating company must have the equipment’s registration number, and the proper 
connections must be ordered. 

To order the proper service, provide the telephone company with the following 
information:

• USOC number of the required jack (shown below)

• Facility interface codes

• Service code

The Federal Communications Commission (FCC) of the United States of America 
and the Industry and Science Canada (ISC), have published regulations which 
govern the allowable limits of emanation of radio frequency energy of computing 
devices and associated peripherals. These regulations are concerned with 
interference to radio communications, such as radio and television. The regulations 
require equipment for use in the United States or Canada to be labeled and to be 
accompanied by the following notice:

This equipment has 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 interference when 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 interference to radio communications.

This digital apparatus does not exceed the Class A limits for radio noise emissions 
from digital apparatus set out in the radio interference regulations of the ISC.
