Note: This chapter only applies to the Standard telephone.

 

This chapter is only relevant when your system is connected to

 

a digital trunk line (ISDN-trunk line). It provides a general

 

view of all the (supplementary) services available from the

 

public net which are supported by the system. The services

 

from the public net differ from market to market. Please ask

 

your system administrator which features are available.
