TRUNKED FEATURES (EDACS/GEMARC)
Preprogrammed DIG/DTMF Numbers
During the PC programming of the radio, the special
call list may be programmed with up to 96 numbers for
EDACS and 96 numbers for GE-MARC, depending upon
available personality space. Using the SPC key, the numbers
can be recalled to initiate the special call.
HOME
The radio will automatically select a desired Group
and/or System by depressing a single key.
Keypad Lock
To prevent undesired key presses, the keypad can be
locked at any time by depressing the LOCK key (shift RCL).
Power Up System/Group
The unit can be PC programmed to automatically select
a desired Group and/or System on power up.
Manual Individual Calls
The radio is capable of making Individual Calls which
are not programmed into your radio. The Individual Calls
are made by manually entering the ID number (EDACS) or
Tone Set (GE-MARC) from the radio keypad.
Manual Interconnect
The radio is capable of making Interconnect Calls
which are not programmed into your radio. The Interconnect
Calls are made by manually entering the telephone number
from the radio keypad.
Store
Individual and Interconnect numbers may be recalled
from a memory location and initiated using the Special Call
Key and RCL key.
Recall Last Number Send
When entering the Special Call mode the radio will
display the number (0-9) of the last accessed Special Call
number.
EDACS (ONLY) FEATURES
Group Scan
The radio monitors the control channel and responds to
all group channel assignments associated with the "scan"
list. The "Priority" group is dictated by the group currently
selected. If a call occurs on the "Priority" group while
monitoring one of the scan groups, the radio will
immediately enter into the "Priority" group.
Automatic Login
The radio automatically transmits the "Login" message
when the radio roams into a new system, when changing the
group selector and when the radio is tuned on. The "Login"
message includes the Logical ID and the Group ID for the
radio.
System/Group Selections
The standard EDACS feature set allows up to 16 groups
total, independent of number of systems programmed.
Optionally, the radio can be configured to provide 128
or more EDACS groups.
Conventional Failsoft
In the unlikely event of a trunking failure,
communications may take place in the Conventional Failsoft
mode. The radio will automatically be directed and will
switch to a communication channel set up for this purpose.
SCAT
The radio will operate in a Single Channel Autonomous
Trunking (SCAT) system.
Base/Mobile Operation
This pre-programmed option is used in some fleets so
units can only hear and talk to a base dispatch unit, not to
other radios in the group.
Priority System Scan (Optional)
A priority or "home" system is pre-programmed into the
radio. The radio unit continually searches (scans) for its
priority system and if found, locks onto it. This improves
network efficiency by preventing unnecessary multi sited
calls.
