4.17Network 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.
