Number of fixed telephony customers

This section breaks down the number of fixed telephony customers according to the type of contract taken out with the TSP. The number of customers accessing services via a direct access (PSTN, ISDN or VoIP) has remained relatively stable since liberalization in 1998.

Notes:
a) Definition before 2003: Subscriptions / of which those with a call number.
b) Definition before 2003: Subscriptions / of which those with manual or "call by call" carrier selection (CSC).
c) Definition before 2003: Subscriptions / of which those with automatic carrier selection.
d) Definition before 2003: Subscriptions / of which those who have changed their operator during the period from 01.01 to 31.12 without changing their number.

In Table SF1A, if the number of contracts is greater than the number of connections, this is due to the fact that there may be multiple contracts on one connection. Indeed, in some cases, a user must have a subscription contract with Swisscom for connection to the network, but may take out a subscription agreement with a different provider for local, national and international calls, in the form of manual "call by call" carrier selection or with automatic and permanent carrier selection.
