All IP


Replacement of TDM and conversion to IP

IP, the packet-based Internet protocol, replaces the previous transmission technology TDM (time division multiplexing) for the fixed-line network.

The conventional fixed-line network technology (TDM) is obsolete and dates from the time before the Internet. This is why the conversion to IP is happening worldwide. 

Swisscom has been changing over analogue telephony to the Internet Protocol (IP) since 2013. By the end of 2017 more than 90 per cent of all customers were enjoying the many benefits of the new technology. The first communities have completely changed over, and whole regions will now follow step by step. The future is now: Switzerland is set to enjoy the new possibilities unlocked by digitisation.

 

Where do we start

What areas are concerned:

The first major regions have been or are currently being converted.

The remaining regions will change over completely to All IP in 2019.


What does the conversion mean for Swisscom Wholesale customers?

Interconnection – conversion to VoIP IC:

The TDM interconnection must be converted to VoIP interconnection.

The new VoIP interconnection products are available, which makes your network connection simpler and cheaper.

 


From BBCS Shared to BBCS naked:

Convert your customers now to the BBCS connection without TDM (BBCS Naked). The conversion makes higher value creation possible for you, as the Swisscom fixed-line network connection is no longer used and you can serve your end customer holistically.

 



Elimination of Carrier Preselection (CPS)

Carrier Preselection, a service dating from the onset of liberalisation, when there was no alternative to the network of Telecom PTT, has been eliminated with the conversion to IP. Of course, the free choice of provider for end customers will remain intact. Switch your customers now to your own voice over IP service. This also means that the customer no longer has an affiliation agreement with Swisscom, and the customer relationship devolves entirely to you.

 

The free choice of the telephony service provider continues to be a given in the IP environment:
