console, the console can be utilized to patch a tele-
phone line to a talk group, a unit, a conventional
channel or a talk-group patch in the CEC/IMC net-
work. At the console, the CD may also be utilized
like a standard telephone by the console
user/dispatcher if radio patch operations are not
transpiring. The console uses a secondary
unit/logical ID (LID) number for the CD patch
channel requests, thus allowing CD patch operation
to work separately from and concurrently with
normal console-to-radio dispatch communications.
This LID is typically referred to as the "Call
Director ID" number.
FEATURE LICENSED OPTIONS
Optional functions are available at the console if the re-
spective feature licensed software options are purchased and
installed on the console. Each feature licensed option is pur-
chased on a per console basis by obtaining a software
license for the respective option. Current feature licensed
options include:
•
CEC/IMC Auxiliary Input/Output (I/O) Moni-
toring and Control Capability
—From the con-
sole, CEC/IMC auxiliary input events’ states can be
monitored and CEC/IMC auxiliary output events’
states can be monitored and controlled. A special
console module type—auxiliary I/O modules—are
utilized for auxiliary I/O indications and control
functions at the console. Each auxiliary I/O module
is assigned to a specific CEC/IMC auxiliary I/O
event.
•
Integrated Tone/Voice Paging Capability Via
Internal Paging Tone Encoder Circuits
—The
console’s audio system includes tone generation
circuits which can generate many standard paging
tone formats; therefore, an external paging tone en-
coder is not required. Supported integrated paging
tone formats (“code plans”) include GE Type 99X,
Y and Z, Motorola Quik-Call II™, Reach, 5/6 and
DTMF. Both manual and preprogrammed
(automatic) integrated paging operation is pro-
vided.
For manual integrated paging operations each but-
ton on the console’s graphical user interface re-
served for this use (6 total) is preset with a specific
code plan such as Type 99X but, when paging, the
user/dispatcher must first select a broadcast en-
tity—typically a conventional channel—to page on
and enter a specific code number before the paging
tones are transmitted. Voice transmissions to the
paged entity may follow.
For preprogrammed integrated paging operations
each button on the console’s graphical user inter-
face reserved for this use (144 total) is prepro-
grammed with a specific code plan, a specific code
number and a broadcast entity, and the
user/dispatcher transmits a page by simply pressing
the respective preprogrammed button(s). Voice
transmissions to the paged entity(ies) may follow.
After consecutively paging multiple entities via two
(2) or more preprogrammed buttons, a simulselect
consisting of the paged entities automatically acti-
vates for subsequent console voice transmission(s)
to the paged entities.
•
Radio Status Message Capability
—The RSM
feature licensed option provides EDACS radio unit
transmitted status monitoring at the console. Indi-
cations are displayed in one or more of the con-
sole’s RSM modules. Per off-line configuration,
each RSM module is assigned a status code number
which corresponds to a unique radio unit-transmit-
ted status code utilized throughout the EDACS
radio system. 128 status codes are available for
RSM and RTT operations.
•
Request-To-Talk Capability
—The RTT feature
licensed option is similar to the RSM option except
the dispatcher may, as desired, individually reply to
a unit requesting communications with dispatch via
a radio status transmission. Dispatcher reply is
accomplished via an trunked individual call to the
unit with the dispatcher being the caller and the
requesting-to-talk unit being the callee. The indi-
vidual call is initiated directly from the respective
RTT module holding the queued-up requesting-to-
talk unit(s). RTT queue status is indicated by dis-
playing radio units’ aliases/names or logical ID
(LID) numbers within the particular RTT module.
DESCRIPTION
PERSONAL COMPUTER SYSTEM
The PC within the C3 Maestro console system provides
most computer processing functions for the console. Soft-
ware includes Microsoft's Windows NT Workstation oper-
ating system and custom console application software de-
veloped by Ericsson Inc. Typically, the console application
software automatically starts just after the Windows NT
operating system boot-up process completes; although,
various start-up options are available based on dispatch
center/system requirements.
PC-related system components include the Central
Processing Unit (CPU) enclosure, the video display monitor
