Installing Telephones and Adjuncts

NOTE:

■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 for an MLX telephone, and an analog multiline-specific IROB for an analog multiline telephone.

■See the documentation packaged with the IROB protector for complete installation instructions.

See the documentation packaged with the OPRE for complete installation instructions.
