It used to be at /webservices/contentchannelservice.asmx. It doesn't look like it's still there.
In 7.5, Content Channel webservice is not installed by default, you'll need to add it through Deployment Center first.
All actions > Expand 7.5.x.x > Expand Modules > Run "Install EPiServer Web Services" on your site.
After that, its default path will be /webservices/contentchannelservice.asmx.
For the record, you're my favorite Norwegian.
That's the way, a-ha a-ha, I like it.
