Custom Key Set

Specialized multibutton telephones designed expressly for a particular private branch exchange (PBX). Unlike the locking buttons on normal key telephones, the buttons on a custom key set are used to communicate with the system and are typically nonlocking buttons. Custom key set buttons can be arranged to activate specific features such as speed dialing and executive override, as well as to select lines.
