Connecting Telephones to the Control Unit
Considerations
Review the following items before you begin the procedure:
■ If the way you connect the telephones differs from the instructions
on the system forms, record each jack and telephone change on
Form 2a, System Numbering: Extension Jacks. See Appendix A,
“System Numbering Forms.”
■ If you use staples to attach the cords to walls or baseboards,
make sure you do not pierce the cords.
■ If an MLX telephone or analog multiline telephone is in a different
building from the control unit, and
is within 1000 ft. (305 m)
of the
control unit, connect the telephone to the control unit, using two
In-Range Out-of-Building (IROB) protectors.
Make sure you use an MLX-specific IROB protector for an MLX
telephone, and an analog multiline-specific IROB protector for an
analog multiline telephone.
See the documentation packaged with the IROB protector for
complete installation instructions.
■ If the single-line or T/R telephone is 1000 ft. (305 m) or further
from the control unit, connect the telephone to the control unit
using an Off-Premises Range Extender (OPRE).
See the documentation packaged with the OPRE for complete
installation instructions.

phones only to MLX modules; a mismatch could damage
the ports and cause them to stop functioning.
Incorrect wiring can result in users not being able to place
outgoing calls. Make sure you use the proper cord. For all
GS/LS modules:
