The 400si 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 com-
pany. 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
to comply with local telephone company tariffs.
TELEPHONE CONNECTION REQUIREMENTS
The Federal Communications Commission (FCC) has established rules which permit the
400si to be connected directly to the telephone network using telephone company net-
work access jacks usually referred to as “Registered Jacks.”
