FCC and telephone company requirements 

If your IBM Aptiva PC has a built-in modem, the 

following Federal Communications Commission (FCC) 

and telephone company requirements apply:

1 The modem adapter card is located in the back of the 

system unit. It complies with Part 68 of the FCC 

rules. A label is affixed to the built-in modem that 

contains, among other things, the FCC registration 

number, USOC, and Ringer Equivalency Number 

(REN) for this equipment. If these numbers are 

requested, do either of the following to see the label, 

and provide this information to your telephone 

company:

•

If you have a minitower system, refer to “Opening 

a minitower system unit” on page 98 for 

instructions on how to open the system unit.

•

If you have a microtower system, refer to 

“Opening a microtower system” on page 98 for 

instructions on how to open the system unit.

2 The REN is useful to determine the quantity of 

devices you may connect to your telephone line and 

still have those devices ring when your number is 

called. In most, but not all areas, the sum of the REN 

of all devices should not exceed five (5.0). To be 

certain of the number of devices you may connect to 

your line, as determined by the REN, you should call 

your local telephone company to determine the 

maximum REN for your calling area.

3 If the built-in modem causes harm to the telephone 

network, the telephone company may discontinue 

your service temporarily. If possible, they may notify
