Philips D721 Telephone User Manual


 
4.17 Network provider code scheme
A network provider code is a special prefix that you dial before the actual
telephone number when using the call-by-call method in order to conduct
the call via a specific network provider.
The network provider code scheme stored in the SmartLine D711/721 is
similar to a mathematical formula and contains all possible codes.
This scheme is necessary for the telephone to be able to compare incoming
calls against the telephone book (if the numbers in the telephone book are
stored together with network provider codes). It is also important for the
discriminator because barred numbers can otherwise be circumvented with
network provider codes.
The network provider codes that are set by default for Germany (five and
six digits) correspond to the state of affairs that applied when your telepho-
ne was delivered and are also not influenced by resetting the unit. In the
event that a change should nevertheless be necessary, we give you an
input example here which indicates how the network provider codes are
composed:
5-digit codes are within the range from 01010 - 01099
digits 1 – 3 penultimate digit last digit
010 1 – 9 0 – 9
Uninterrupted input of the previous line: 0101-90-9
6-digit codes lie within the range from 010000 - 010099
digits 1 – 4 penultimate digit last digit
0100 0 – 9 0 – 9
Uninterrupted input of the previous line: 01000-90-9
A maximum of 30 characters including special characters is available.
