NEC Push-to-Mute (PTM) or Push-to-Talk (PTT) Handset

The PTM (780503) or PTT (780504) handset has a single-pole,

single throw switch that must be continuously held down to provide

the feature.

These replacement handsets for DTH terminals help to ensure a

secure telephony environment by keeping unwanted audio from

being transmitted over the corporate telephone network.

Using the PTM or PTT handset on an NEC digital terminal prevents

eavesdropping and eliminates the worry that privileged information

could be transmitted without user authority. These handsets are also

an ideal solution to filter unwanted audio transmissions from

environments with ambient background noise.
