<class> integer or sum of integers each representing a <class> of information:
1 voice
2 data
4 fax
8 short message service
16 data circuit sync
32 data circuit async
64 dedicated packet access
128 dedicated PAD access
x combination of some of the above classes.
For example, the default setting 7 represents the sum of the in-
tegers 1, 2 and 4 (call barring for voice, data and fax). The
value 255 covers all classes. If the <class> parameter is omit-
ted, the default value 7 is used.
See examples in 4.21.3 for the correct handling of class numbers.
<class> 2 (data) comprises all those <class> values between 16 and 128,
that are supported both by the network and the MS. This means, a set-
ting made for <class> 2 applies to all remaining data classes ( if sup-
ported). In addition, you can assign a different setting to a specific class .
For example, you can activate Call Barring for all data classes, but deac -
tivate it for a specific data class.
