terminals that a system can accommodate. For example, you can have up to 60 stations with either the Simultaneous Voice and Data feature or Voice Announcement to Busy Voice Terminal feature. These two features require an additional voice pair so that they can transmit either voice or data or indicate to a caller that a voice terminal is busy.

To add a voice terminal to the system, do the following:

Check the modules for unoccupied voice terminal jacks, and determine that all of the following conditions are met:

•There are fewer than 120 stations connected (R3 only). There are fewer than 72 responding stations connected (FM1 and FM2).

•There is an unoccupied jack.

•You have the correct type of voice terminals for the unoccupied jack.

If all three of the above conditions exist, you can add voice terminals to the system by connecting the voice terminals to the available voice terminal jacks.

NOTE: If all voice terminal jacks on all modules are occupied, you can add a combination of station modules to increase the system’s capacity to 120 voice terminals. Contact the equipment supplier to order additional voice terminals and line modules.

To install the modules, see the instructions in the procedure, “Module Installation” on page 2-62.
