Motorola APX 7500 - Transmit Priority; Table 4-6. Response Table

September 9, 2011 68009482001
4-16 Feature Operation: Wireline Interface
• Radio Enable/Disable - allows the Console user the ability to make unusable (Inhibit) a specific
subscriber and correspondingly restore a unit to normal operation (Un-Inhibit).
• Radio Check - allows the Console user the ability to remotely ping a specific subscriber.
• Remote Monitor - allows the Console user the ability to remotely put a specific subscriber into
transmit mode.
The corresponding response (e.g. ACK) transmitted by the specified subscriber and then received
by the Consolette will be passed up to the Console. The Console retries supplementary data
messages when the required acknowledgment is not received in time.

4.12.4 Transmit Priority
There are several sources of PTT on the rear panel of the Consolette and the user can select one of
these to have the highest priority in the event that more than one PTT is active at the same time. On
the Audio Parameters Page (Figure 3-9), there is a field called “Rear Panel PTT Priority” with the
following selections:
• Priority None – when selected, all PTTs (TRC, ACIM, Headset PTT, Crosspatch/HW PTT) on
the rear panel are handled on a first come first served basis.
• Priority Headset – when selected, the Headset PTT is given the highest priority.
• Priority Crosspatch/APCO (Aux TX) - when selected, either the Crosspatch or the HW PTT is
given the highest priority. The user can enable either the Crosspatch or the HW PTT inputs
using the Crosspatch/APCO field. The APCO/HW PTT will operate as a typical logic PTT with a
single ended audio path (Aux_TX) or the Crosspatch interface can be enabled with the
corresponding Crosspatch PTT.
• Priority Wireline – when selected, the PTT source associated with the Wireline balanced audio
path is given the highest priority. The user can set up the Wireline PTT source using the
Wireline Function field. Selections are either TRC operation, ACIM operation, or APCO
operation. Note that when TRC is selected as the Wireline Function all other rear panel PTTs
are disabled- the Wireline must always be routed for tone decoding.
