Page 1002 of 3156 China – Flexible Feature Codes
553-3001-306 Standard 10.00 January 2002
Feature description
Three Flexible Feature Code (FFC) features have been developed to meet the
requirements of the Chinese Ministry of Posts and Telecommunications for
the rural switch market in China, these features can be used in other markets.
The three features are Busy Number Redial (BNR), Customer Call Forward
(CCFW), and Outgoing Call Barring (OCB). With all three of these features,
there is an option to provide a confirmation tone upon feature activation.
Busy Number Redial
Busy Number Redial enables a user of an analog (500/2500 type) telephone
encountering a busy condition to automatically redial the busy number by
performing a switchhook flash and dialing the Busy Number Redial FFC.
When the user goes off-hook next without dialing any digit, the busy number
is automatically redialed. This feature remains in effect until the desired
Directory Number (DN) is reached, up to a maximum of 20 minutes.
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.
