Figure 1: M2016S Secure Set
The M2016S Secure Set is a Telephone Security Group (TSG)-type,
accepted Class 2 set. The M2016S Secure Set is designed to provide
on-hook or idle state security, preventing it from being used as a passive
listening device when the handset is in the on-hook position. The M2016S
uses relay circuitry that physically disconnects the handset from the
telephone circuit when the switchhook is depressed.
In addition to its message waiting indicator function, the Message Waiting
Indicator is used to indicate the security state of the M2016S Secure Set.
The red triangle lights steadily when the set is not secure – typically when
the handset is off-hook, when the set is ringing, or anytime the handset/
piezo relays are connected. The red triangle blinks when a message is
waiting.
