Uniquely programmed Programmable Function Keys that provide an
appearance for outside lines (trunks) not assigned to a line key. There are
two types of Loop Keys: Switched Loop and Fixed Loop. For incoming
calls, both Switched Loop and Fixed Loop Keys provide an appearance
for any trunk not assigned to a line key. For outgoing calls, Switched
Loop Keys simplify access to trunk groups. Fixed Loop keys provide
access to a specific trunk group.
