You can customise default filters for your needs before you apply
them. You can
• create a new restriction filter
• add or remove restrictions
• add or remove overrides
• You can have up to 100 restriction filters.
• There is a maximum of 400 restrictions and overrides
allocated to the 100 programmable filters.
• Each programmable filter can have up to 48 restrictions. There
is no limit on the number of overrides that can be allocated to
a restriction.
• You can use any restriction or override in more than one filter.
Each time it is used, it counts as one entry. For example, if
restriction 411 exists in filters 01, 02, and 03, it uses up three
of the 400 entries available.
• The maximum length of a restriction is 15 digits. The
maximum length of an override is 16 digits.
• You can use • and £ in a sequence of numbers in either a
restriction or an override. These characters are often used as
part of feature codes for other systems or for features provided
by the public switched telephone network (PSTN).
• The solid dot (•) can represent any digit. It is inserted by
pressing ANY.
