Basic PMR Voice Services (and more)
Excellent voice quality of ACELP codec
Group calls– Wide area groups up to nationwide– Fast call set-up– Virtually unlimited number of talkgroups– Economic use of resources
Individual call (semi-duplex)– Direct call i.e. press and talk– Hook call i.e. answer when it rings
Mobility management and fast cell reselection
Basic Mobile Telephony
Individual call (full duplex)– Radio to radio– PSTN/PABX/ISDN
connectivity
Mobility management and fast cell reselection
Before TETRA this was not self-evident
Advanced PMR Voice Services
Pre-emptive Priority Call (PPC, emergency call)
Call queuing when resources busy
Priority Call up to 16 priority levels (PC & PPC)
Late Entry (LE)
Ambience Listening (AL)
Call Authorised by Dispatcher (CAD)
Discreet Listening (DL, monitoring of calls)
Dynamic Group Number Assignment (DGNA)
