ITL/DTL PTM Handset
The Push to Mute (PTM) handset has a single-pole, single-throw switch that must
be continuously held down to provide local mute.
These replacement handsets for ITL/DTL terminals help to ensure a secure
telephony environment by keeping unwanted audio from being transmitted over
the corporate telephone network.
Using the PTM handset on an NEC digital or IP 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.
