RSP contirbutions to 401k: count towards max?

[red92s]

I've just started receiving RSP (retirement savings plan) contributions to my 401k from my employer. These are not "matching" contributions, but a pension-type payment that goes to the 401k account (with my current length of employment, equal to 2% of my annual salary).

I know that employer matching contributions do not count towards the yearly $15,500 max. Does this go for ALL employer contributions (like the RSP payments above), or is it specific to matching contributions?
