CONTENTS
The PROSTAR DCS may be configured as a key system or a hybrid system. Depending
on the method of operation, the appropriate FCC number must be given to the telephone
company. Certain features such as pooled access by button or dial access, LCR, off premise
extensions and tie lines may require the hybrid registration. Check with the local tele-
phone company providing the service if you are in doubt. It is the customer’s responsibility

DCS to be connected directly to the telephone network using telephone company network
access jacks usually referred to as “Registered Jacks.”
