Coded Clear
A signaling system which provides a scrambler “on or off”
command to a Motorola Secure equipped station prior to
each key up. Two LED’s indicate coded or clear transmissions.
Allows for system integration of secure stations.
Auxiliary I/O’s
General relay inputs and outputs can be used for supervisory
control, main/standby, audible alarms, voting receiver
comparators, control of external functions such as a security
camera or a magnetized door. Twelve opto-coupler inputs
and six form-C relay outputs are available with each optional
I/O module. Up to 4 I/O modules can be added to each
console. Provides user with additional system control.
Operator Crossmute
Acoustically mutes a channel at one operator position every
time another operator is transmitting on the same channel(s).
Useful when operator positions are located near each other in
the same dispatch center to eliminate the possibility of
acoustic feedback between positions.
Channel Crossmute
The receive audio is automatically muted on desired
channels when a crossmuted channel is keyed. Helps
prevent cross-station interference from being heard.
Intercom
Buttons can be configured to intercom with maintenance
personnel located at specific base station sites or other
operator positions. Dispatchers can engage in productive
communications without using the airwaves.
SIGNALING FEATURES FOR TONE, DC OR E&M KEYING
Integrated Paging Encoder
Supports industry-standard paging formats: Motorola 2-Tone,
Quick Call I & II, DTMF, 5 tone, 6 tone, GE99, NEC5, NEC6,
Reach 1+1, Plectron, Pulse and Custom page formats. Helps
eliminate the need to deplete space and resources to accom-
modate an external encoder.
One Button Paging
Buttons on the Auxiliary Control Module(s) can be pre-defined
with paging destinations; including channel, frequency, page
format, and cap code. A single page transmission can be sent
out to multiple pagers by depressing up to 16 page buttons
prior to page transmit. Provides a fast and accurate paging
method.
Alias Paging
Aliases, preprogrammed with the proper page code and
destination, are recalled on the Keypad module display with a
button press. Selecting the correct alias by scrolling through
the list, and pressing page transmit sends the page over the
correct channel and frequency. Up to 512 aliases are possible.
Does not require the availability of multiple ACM buttons.
Multi-Select with Memory and APB
Radio channel combinations can be grouped and stored for
simultaneous transmission, such as an All-Points-Bulletin.
Up to 8 channel combinations can be stored in memory and
recalled when needed. Dispatching the same message to
multiple channels with a single transmission saves time.
Patch with Memory and Instant Transmit
Any combination of available radio channels can be patched
together, regardless of band, with any number of available
phone lines or call director circuits. The customer can recall
these combinations, which are stored in memory, at any time
and choose to interface with the patch or proceed with other
activities. Up to 5 simultaneous patches are possible per
operator position. Storing patch combinations in memory
allows customers to be more productive. Linking channel
users allows for a more reliable transfer of information.
Stat-Alert Signaling
MDC 1200 data signaling format supports the following
functions on a per channel basis using a DCCM with display.
PTT ID encode/decode, Radio Check encode, Emergency
Alert decode, Call Alert encode/ decode, Voice Alert
encode/decode, Smart Status/Message decode, Vehicle
Status Request, Radio Inhibit and Enable, Repeater Access
enable and disable, Repeater Access Code, Remote Monitor,
Queue, and Data Operated Squelch. Allows users to manage
their mobile fleets in a more efficient manner by inter-mixing
voice and data transmissions on a standard radio channel.
Data can be decoded per channel, allowing for a clear
separation of channel activities.
DTMF Decode
DTMF data signaling format supports two modes
of operation, to ease the migration from DTMF to MDC
1200 systems:
1) Automatic Number Identification (PTT ID) with Alias
2) Pager function – radio channel is muted until distinct
DTMF digits are received.
