10 is very high and will probably result in a lot of innocent PB kicks for connection issues, and also cause some lag.
I recommend you use the pbsvuser.cfg for BF2142 from the MCI, which you can find here; it has all the content you need.
You don't send these commands to your server btw, you put that line into your pbsvuser.cfg directly on your server. You should be able to edit that file through a gamepanel that your GSP have provided.
If you don't have access to your PB files, I suggest you contact them and ask them to put it in for you.
