SECTION 6 OPTIONAL HANDSETS
6.1 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.
6.2 ITL / DTL PTT Handset
The Push to Talk (PTT) handset has a single-pole, single throw switch that
must be continuously held down to transmit local audio.
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 PTT 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.
