I honestly cannot remember connecting a S/L set to a GLX, unless it was connected to the DATA port on an executive key set. Is the S/L connected to a keyset?

But then if you have a Inter-tel GLX-Plus:

Lift the handset
Enter the CO line access code(s) that are to ring.
Hang up

If you have the manual the instructions are on page 5-13 paragraph 5.8
