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.
