!WARNING:

If you must check something on the control unit, proceed with caution. Avoid standing on a box or chair to reach the unit if it is installed out of easy reach. If you do not have a stable ladder or other proper equipment, do not proceed; wait for the Lucent Technologies technician.

Possible Cause 6: A module or modules may be defective.

What to do: Identify the control unit module or modules where the telephones are connected.

■If the telephones are all connected to one module, there may be a problem with the module. Call the Lucent Technologies Helpline at 1 800 628-2888 (consultation charges may apply).

■If the dead telephones are connected to modules that also connect working telephones, test the jacks on the modules. Identify the port where each nonfunctional telephone is connected. Identify a second port in the same module connected to a working telephone and unplug the jack from the module. Plug the jack for the dead telephone into the extension jack that is now open. If the telephone works, call the Lucent Technologies Helpline at

1800 628-2888 (consultation charges may apply).

■If the telephones do not work when plugged into module jacks that are known to be functioning, call the Lucent Technologies Helpline at

1800 628-2888 (consultation charges may apply).

!SECURITYlALERT:

When changing calling restrictions and other security settings, take care not to compromise the security of your system. For more information, consult

‘Security‘ of Your System: Preventing Toll Fraud’’ in Appendix A, ‘Customer‘ Support Information’’.

Possible Cause 1: This extension is restricted from making outside calls.

What to do: Use system programming to check the extension’s calling restrictions, if any (see Chapter 3 in System Programming). If the extension is toll- or outward-restricted, change it to unrestricted, if appropriate. Try again to make an outside call from the extension.

■If outside calls can now be made from the extension, you have solved the problem.

■If there is still difficulty making outside calls, go to Possible Cause 2.
