If you are not a UK communications provider with consumers as customers, this site is not for you.

Why would someone use this?

Under OFCOM General Conditions, One Touch Switching is mandatory for all UK fixed broadband and fixed telephony providers with consumer customers, even if just retail providers of someone else's service.

One Touch Switching is managed by TOTSCO Ltd. But at this point their simulator seems not to be fit for purpose, and does not follow the OTS specification even for simple things like the URL paths used (see blog post). This site is designed to provide an easy to use, useful, self service platform, with no need to book a test slot. It means it can be used to test as you go during development if you want. It should be useful to any CP that is developing One Touch Switching (before you go on to TOTSCO testing). It may also be useful to CPs that have already developed their One Touch Switching that want to check against an external test system.

We have tried to follow the spec, let us know if you think there is any error. Please bear in mind the specifications are woolly at best. We have tried to reference the specification as much as possible, but some is based on examples, clarifications, bulkletins, and messages actually seen from TOTSCO. We're happy to take on suggestions in improving our checking.
