Extensions are entered into different Classes for barring purposes. There are 6 classes selected under 'Extension' programming. There are also four tables of codes selected in 'System' programming which determine additional codes that are barred or allowed:

•Select 'Extensions'

•Select Restriction classes

•Select 'Day class of service' or 'Night class of service'

•Select the class and enter the extensions

•Class 1 is no calls barred

•Class 2 is International calls barred. Also any additional codes added to Table 2 in Class codes programming are barred

•Class 3 is National and International numbers barred. Also any additional codes in Tables 2 and 3 in Class codes programming are barred.

•Class 5 is associated with extensions when codes entered in the 'Allowed Table’ in Class codes programming are to be allowed. This is combined with Classes 2 and 3

•Class 6 is the additional restriction codes in the Restricted Table in Class Codes programming. These can be combined with Classes 1,2 and 3.

Note: As the BT Versatility can support both ISDN and Analogue, it may be necessary to enable features for ISDN and Analogue options on the same system.
