29 Use of access codes
(1) An access code identified in columns 1 and 2 of an item in a table in Schedule 6 may be used only for a type of carriage service mentioned in column 3 of the item.
(2) The access code may be used only as a prefix to a type of number mentioned in column 4 of the item.
(3) An access code is specified for use with a type of service if the type of service is mentioned for the access code in column 3 of a table in Schedule 6.
(4) Despite subsection (1), a carriage service provider identification code may also be used:
(a) to identify a telecommunications network; or
(b) to interconnect routing of a call between carriage service providers;
without being dialled, and may prefix an address digit for routing a call across a point of interconnection.
(5) Despite subsection (1), an access code that is specified for use with an incoming only international service that is also a special services number specified for use with a type of service may be used for both purposes.
Note: See section 22 and Schedule 5 for specification of the use of special services numbers. The same number can be used for both purposes because one use will be for calls originating in Australia and the other will be for calls made from outside Australia.
