420 China - Flexible Feature Codes
Customer Call Forward
Customer Call Forward allows users of analog (500/2500 type) telephones
to forward their telephones to a central answering position by dialing the
Customer Call Forward FFC. This feature activates the Call Forward All
Calls function without having to specify the forward DN.
Outgoing Call Barring
Outgoing Call Barring allows a set to be blocked from making some or all
outgoing calls. Three levels of barring are available which can be selected
by dialing the Outgoing Call Barring FFC, the barring level desired, and the
Station Control Password (SCPW).
The three levels are each associated with a New Flexible Code Restriction
(NFCR) tree in the Customer Data Block. When a DN is dialed, the digits
dialed are compared to the associated NFCR tree and busy tone is given if
the call is barred. An FFC is also available to verify that the feature is active.
The active level cannot be changed without first deactivating the feature
and reactivating it with a new level.
Operating parameters
Although designed for China, the China – Flexible Feature Codes feature
can be used in other markets.
Busy Number Redial is only available for internal calls and for trunk calls
that provide a busy signal when busy tone is given.
Busy Number Redial and Customer Call Forward are only available for
analog (500/2500 type) telephones.
Outgoing Call Barring does not apply to BRI sets.
The Reply DN for CCFW is limited to 16 digits.
OCB will only process asterisk (*) and octothorpe (#) according to the active
NFCR tree if the digits are to be outpulsed on a route with OPR active
(including all necessary conditions for OPR). If they are dialed as part of
an FFC, the call is allowed; otherwise, an octothorpe will cause the call to
be blocked. An asterisk (*) is ignored, except during digit counting. Thus,
FFCs containing an asterisk (*) or an octothorpe (#) cannot be blocked by
this feature.
OCB will not prevent calls from terminating when there are too few dialed
digits to traverse the full NCFR tree (for example, if the active tree is set
up to bar 2001, but a DN of 200 exists, calls to 200 is allowed with no
error message).
