wires, turn the screw counterclockwise, slide
the wire beneath the spring, and then tighten
the screw. You may use up to 14 AWG
stranded wire.
Note that you do not have to connect a ground
to the unused connections on the terminal
block.
5. Connect the module’s rear interface
module to the FOCUS chassis.
After connecting the telephone or PBX, attach
the module’s rear interface module to the rear
of the FOCUS chassis so that it connects to
the Addressable Two-Wire Voice Module.
Make sure you install the rear interface
module on the rear of the chassis in the same
slot as the Addressable Two-Wire Voice
Module.
This completes the hardware installation.
20.3.2 Software Settings
Once you have completed the hardware installa-
tion and connections, the next step is the software
settings. The only setting required is assigning the
module its three-digit address, or phone number.
In addition to setting the module’s address,
however, you must also map, or assign, its DS0
time slots before putting it into operation. You can
do both of these using the FOCUS Configuration
Software (FCS).
