Multi-Button Electronic Telephone (MET) Sets

These DIMENSION® PBX voice terminals have some of the capabilities of System 75 and 85
multi-appearance terminals (see Figure 1).
The MET sets are available in 10-, 20-, and 30-button versions. These three types of MET sets
can be used with DEFINITY G1, G2, G3, System 75, and System 85. The 10-button version can
be desk or wall mounted. All the others must be desk mounted. The 10-button version can be
equipped with a built-in speakerphone. The MET sets can be ordered using PEC code 3140 and
the appropriate suffix.
On the System 85 and DEFINITY G2, the bottom five buttons on a MET set become fixed feature
buttons. On a 5-button MET set, that leaves no room for call appearances, therefore the 5-button
MET set cannot be used with the System 85 and DEFINITY G2.
