Noise Control Module

Noise Control Modules are used to reduce the common noise for example, noise that is present on both conductors on the Signaling Line Circuit (SLC). The Noise Control Module allows the use of untwisted, unshielded wire on the SLC. Applications that have audio or fire fighters’ telephones require the use of twisted/shielded wiring for all circuits including the SLC. The NCM may also be used in these applications to further reduce the common mode noise.
