ISPCs are signalling codes used worldwide in the SS7 signalling networks (Signalling System No 7).
Please note the following when ordering an ISPC:
- ISPCs are not freely selectable and are allocated to telecommunications service providers by the Federal Office of Communications (OFCOM).
- ISPCs must be used in a system located in Switzerland and may not be put into operation abroad.
- ISPCs allocated by a foreign regulatory authority may not be put into operation or used in Switzerland, even if the authority in question permits this.
