Dfsi Features; Fallback In-Cabinet Repeat - Futurecom PDR8000 Manual

PDR8000 may be directly connected to any console supporting DFSI Protocol Version 1, for
example Motorola's AVTEC Scout Console. Connection to Motorola's ASTRO Core can be
made via a gateway device.

EATURES
The following list describes the features supported by PDR8000 when connected to a host
which supports DFSI Protocol version 1.
•
IP based interface between a fixed station and a Conventional Fixed Station Host
(CFSH)
•
Transport of clear audio between a fixed station and its host providing capabilities for
full-duplex, half-duplex and simplex communications at the discretion of the fixed station
•
Transport of encrypted audio between a digital fixed station and its host
•
Control signaling between a fixed station and its host to provide a simple "Push-to-talk"
(or begin and end voice transmit/receive signals)
•
Control signaling from a host to a fixed station to provide a variety of control functions
including channel control, squelch control and monitor control
•
Caller-ID information between a digital fixed station and its host. This includes Unit ID
from field units to consoles, and "Console ID" from consoles to field units
•
Talk-group information between a digital fixed station and its host
•
NAC code information between a digital fixed station and its host
•
Emergency Alert messages from the digital fixed station to its host
•
Emergency indications along with the voice stream between the digital fixed station and
its host
•
Advanced Control of the fixed station by its host including the disabling of all squelch
(monitor function)

ALLBACK
In configurations where a PDR8000 is not normally repeating CAI received information back
through its CAI transmitter (e.g. in a full-duplex Base Station configuration, or in Repeater
configuration after console has issued a Repeater Knockdown command), the PDR8000 can be
configured to temporarily activate its Repeat functionality in certain failure conditions. This
ability is provided to handle cases where the Repeat functionality normally provided by the
system is curtailed due to an unexpected event. If the PDR8000 gets disconnected from the
comparator or console, the PDR8000 can temporarily activate its own Fall Back In-Cabinet
Repeat functionality to allow subscriber-to-subscriber communications to continue.
Fallback In-Cabinet Repeat is configurable to be automatically triggered by different events. A
PDR8000 can be configured to automatically begin Fallback In-Cabinet Repeat if the wireline
link goes down. If desired/configured Fallback In-Cabinet Repeat can also be triggered by
detecting a lack of audio repeat activity (by an external entity) on the wireline link, based on
expiration of a configurable timer. (For instance, if received RF audio is sent to the wireline, and
no observed repeat of audio is received on the wireline for a configurable time, Fall Back In-
Cabinet repeat behavior can be activated.) In these cases, Fallback In-Cabinet Repeat
