asterisk users - Mar 2006 - Attended call transfer with GXP-2000

Can someone explain me attended transfer with Grandstream GXP-2000?
Hitting TRNF button, I get:
 Dial number (BLIND) or
 Select line (ATTENDED)
What's the exact meaning of 'Select line'?

Thanks
Mimmus

If you have Line 1 on hold, and you on a call on Line 2, then hitting TRNF
and hitting Line 1 will transfer Line 2 to Line 1. Same concept as
Conference.
