Pre-Emptive Calling; Receiving An Emergency Group Call During A Call; Receiving A Private Ppc During A Call - Motorola TETRA MTP850 Feature User Manual

Pre-emptive Calling

Pre-emptive calling is particularly useful when you need to
speak urgently with a user whose terminal is busy in a non-
emergency voice call.
A pre-emptive priority call (PPC) is either an Emergency
Group Call or a Private PPC (half-duplex or full-duplex call).
The feature allows to disconnect the on-going lower priority
call and to connect to the incoming higher priority call.
To place a PPC, see the Emergency Operation and Private
Call sections in the user guide.
The MTP850 will receive the call via speaker or earpiece,
according to the setting used when the PPC is received.
For call alert, see settings in the Vibrate menu option (page 90) and
the Tones menu option (page 93)
Receiving a PPC is explained in the following paragraphs.
In the screens,
emergency voice calls: Group, Private, Phone, or PABX.

Receiving an Emergency Group Call during a Call

The MTP850 receives the Emergency Group Call, drops the
on-going non-emergency voice call, and connects to the
Emergency Group Call.

Receiving a Private PPC during a Call

If configured by your Service Provider, the MTP850 receives
the PPC, drops the on-going, non-emergency, lower priority
voice call, and connects to the higher priority Private Call.
A PPC with lower or equal priority, will be dropped without
any indication to the called user and will enter the missed call
list.
