178 Matrix ETERNITY NE System Manual
DSS Key Interface
This parameter determines what the system should do when an external called party in speech on this trunk is put
on Hold by an extension user by pressing a DSS key to dial another port.
For example, the DKP extension user on DKP1 port is in the middle of speech with an external party on a CO2.
If the extension user of DKP1 presses a DSS key to call another extension port, DKP2, two situations are possible,
depending on the DSS Key Interface you configure:
i. The external caller on CO2 will be played music-on-hold, and the user on DKP1 will hear Ring Back
Tone. The call will be placed on DKP2.
ii. The external caller on CO2 will be disconnected. DKP1 user will hear Ring Back Tone. The call will be
placed on DKP2.
