You can both encode and decode in the APX line as long as you have the following option in the radio:
DIGITAL TONE SIGNALING
Reduce response time to an incident by instantly alerting
large groups of on-duty and
off-duty responders over their APX radio.
•Commonly used in Fire Rescue to alert first responders
to an incident by broadcasting a series of distinct, rec-
ognizable tones followed by a voice transmission from
dispatch.
• This allows an entire fire department to be simultane-
ously alerted to an emergency
situation, as opposed to unit to unit dispatch (Call Alert)
which takes longer.
• It allows the responder to keep their radios in a quiet/
silent mode until a critical alarm is raised.
• This feature works on P25 Conventional or Trunked
systems, providing digital quick call II operation that is
identical in operation as the legacy analog version.
•By 7.15.5, the feature will support encode from an APX
portable or mobile with a DTMF keypad.
Portables: QA09000
Mobiles: QA09000
Dependencies: P25 operation (Digital CAI)
I can send tones out on both my 7000 & 7000XE on both conventional and on Trunked.
The help menu in APX CPS should clarify more and if I get some time tomorrow I will try to record a video showing my APXs sending and receiving QCII tones.
