INTRODUCTION

The operational policies contained within this handbook
were developed as specified in the Joint Agreement for the
Implementation and Operation of the Orange County 800
MHz Countywide Coordinated Communications System
(CCCS).

The history of law and fire communications in Orange
County has proven that the ability for common
communications among all agencies dramatically improves
the delivery of services to the public. The only available
frequencies for any radio system expansion were in the 800
MHz spectrum. The County was licensed on 61 new 800
MHz channels, and for the first time in Orange County
history, all public safety agencies now operate on one
common frequency band. The 800 MHz Countywide
Coordinated Communications System (CCCS) is an 81-
channel radio communications system enabling
interoperability among all participating City and County
law, fire, public works and lifeguard/marine safety
departments. The 800 MHz CCCS was designed for
complete interoperability among all public safety agencies
in Orange County.

The 24-hour Countywide Coordinated Communications
Center (Control One/OCC) is equipped to communicate on
all trunked talkgroups, conventional 800 MHz repeaters, as
well as other VHF and UHF radio systems utilized for
public safety operations and coordination. The facility is co-
located with the County’s Emergency Operations Center and
the Sheriff’s 9-1-1 PSAP. At Control One/OCC, radio,
microwave and telephone circuits interconnect all public
safety agencies and hospitals throughout Orange County
allowing coordination between federal, state and local public
service agencies as well as private and volunteer
organizations.

RADIO SYSTEM OVERVIEW AND
SYSTEM FEATURES

The 800 MHz CCCS utilizes two radio technologies,
trunked and conventional.

What is trunking? In the context of radio communications,
a trunk is a communications path. A good analogy is a
single-lane road. If someone is stopped ahead of you on the
road, you must wait. This is a problem with large radio
system users. If someone is talking on a channel that is
shared among a group of users, you must wait until the
channel is clear to transmit. A look at the telephone system
can provide another analogy. The Telephone Company has
been using trunking techniques for about a century. Each
telephone user does not have a dedicated private trunk for
every call made. When the user establishes a call, it is
assigned to a trunk for the duration of that call. After the
user hangs up, the same trunk becomes available to other
users. Thus, a small number of telephone trunks can be
shared by a large number of subscribers. The switching
equipment in the telephone company central office manages
the sharing efficiently and automatically.

Radio trunking techniques are applied for the same
fundamental reasons as those used by the telephone
companies. The trunking technology allows a large number
of users to share a small number of trunks (in our case,
frequencies). The effectiveness of trunking is based on two
fundamental characteristics. First, the percentage of time
that any individual user requires a trunk (frequency) is very
small compared to the total time available, and second, the
probability that many users will require a trunk at the same
time is exceedingly small.

4

Each trunked radio system has a number of communications
paths, known as talkgroups. In a non-technical sense, a
talkgroup is the same as a channel. Within the 800 MHz
CCCS, any reference to a “talkgroup” indicates a trunked
system communications path, while a “channel” indicates a
non-trunked, or conventional communications path.

The 800 MHz CCCS is actually several trunked radio
systems. These systems, or cells, provide radio coverage in
a specific geographical area of the County. Several
frequencies are assigned to each cell, and those frequencies
are available in a shared pool. When a user presses the
transmit button, our trunking system controller assigns a
frequency to that talkgroup for the duration of the
transmission. Once the transmission is over, the frequency
goes back into the pool for reassignment. With a number of
frequencies available, the likelihood that all of them being
unavailable at any one time is small. Normal day-to-day
operations are conducted on one of six trunked simulcast
cells. Each cell has a set number of transmitters and
frequencies and a normal operating mode with several levels
of failure modes. These cells are known as Countywide,
North, Northwest, South, Southwest and Laguna.

Simulcast Cell – This is the normal mode of operation. A
set of transmitters/receivers will receive a radio transmission
and re-transmit a radio signal simultaneously over a specific
geographic area. The name of the cell indicates the general
coverage area for each trunked cell in the 800 MHz CCCS.

IntelliRepeater – A single site trunked repeater. The
IntelliRepeater is utilized in areas of poor radio system
coverage. The 800 MHz CCCS has several IntelliRepeater
sites.

5

Out of Range – This condition is identified by the radio
display indicating “OUT OF RANGE” accompanied by a
low continuous tone when an attempt is made to transmit.
This indicates one of two conditions. First, the radio may
simply be out of range of the trunked radio cell being
attempted. Second, the trunked radio cell may be
completely disabled and non-functional. In either scenario,
contact on another trunked cell or conventional channel
should be initiated.

What is Conventional? The other radio technology used
within the 800 MHz CCCS is known as conventional. In
addition to trunked radio systems, there are conventional
radio systems to provide supplemental coverage in specific
areas.

Standalone Repeater – A single site repeater that receives a
signal on one frequency and re-transmits that signal at a
higher power on another frequency. This allows radio users
in a specific geographic area to hear radio transmissions
from a single user. Standalone repeaters are used for
interoperable communications, trunked radio system failures
or when the trunked radio system does not provide the
necessary radio coverage.

Simulcast Repeater – A multiple site repeater system that
receives a signal at one (or more) of the radio sites, re-
transmits the clearest signal at a higher power on another
frequency, over multiple transmit sites. This allows radio
users over a large geographic area to hear transmissions
from a single user. A simulcast repeater system is used for
interoperable communications, trunked radio system failures
or during an incident when the trunked radio system does
not provide the necessary radio coverage.

6

Talkaround – A mode of communication that bypasses, or
“talks around” the repeater. This is a short range, line-of-
sight radio communications mode, also know as simplex or
direct. Mobile and handheld radio users use talkaround
only. Dispatch Centers and base stations can not transmit on
any talkaround channel. Talkaround shall be used when
short-range unit-to-unit communications is required.
Talkaround may also, in various situations, provide better
radio signal penetration into some areas, such as buildings,
tunnels, basements and canyons.

Transportable Repeater – A single site repeater that is
portable and mobile, able to be transported to any accessible
location for deployment. A transportable repeater operates
in the same manner as a standalone repeater, although the
actual coverage is generally smaller than repeaters in fixed
locations. Transportable repeaters are available through
Control One and are used when radio coverage is
insufficient from trunked, standalone and simulcast repeater
systems.

Continuous Tone Coded Squelch System (CTCSS) – A
sub-audible tone transmitted on conventional radio channels.
This tone allows radios programmed with the same tone to
hear those transmissions and block out transmissions from
others using another tone. This feature is known as Private
Line (PL) on Motorola radio equipment. CTCSS is used on
all conventional radio channels utilized in the Orange
County system.

Encryption – Law enforcement specific talkgroups and
conventional channels (except Red), as well as the Fire 7C
Arson and Common 8A PIO-PIO talkgroups operate in the
encrypted mode. Digital radios with the encryption option
are required to use encrypted talkgroups and channels.

7

Encryption (continued) – If a radio does not contain the
correct encryption code, “KEY FAIL” “SECURE ONLY”
and/or an error message will appear on the radio display and
communications on that talkgroup will not be possible. The
radio will continue to receive and transmit on all non-
encrypted talkgroups and conventional channels. When
urgent or emergency communications are necessary on an
encrypted talkgroup and the radio is not coded properly for
encryption, radio users may contact Control One on RED,
9A TAN-CALL or 12A I-CALL. Control One will relay the
urgent or emergency information to the appropriate agency.

FAILURE MODES OF OPERATION

The 800 MHz CCCS has many levels of redundancy. If a
failure should occur to the trunked radio system, users may
need to make operational adjustments. In some failures the
radio user does nothing. More serious failures require
specific actions be taken.

Site Trunking – A condition that may occur when one or
more transmitter/receiver sites in a specific trunked cell lose
the ability to communicate with the Zone Controller. When
in Site Trunking, the radio will display “SITE TRUNKING”
and users may experience reduced coverage in the specific
cell.

Failsoft – A condition that occurs when the trunked cell
fails and can not perform trunking. When this occurs, the
radio automatically switches to a predetermined frequency
and functions like a conventional repeater. A limited
number of frequencies are available during Failsoft making
it necessary to combine a number of talkgroups together
during Failsoft. For this reason radio traffic from other
agencies or departments will be heard and is normal when in
the Failsoft mode.

8

Trunked System Failure – If a trunked cell fails
completely, users must switch to another trunked system or
to a conventional repeater. If all six trunked cells are lost in
a catastrophic disaster, conventional repeaters (RP) shall be
utilized. If all conventional repeaters fail, talkaround (TA)
will be the only mode available. The following policy has
been established for partial or total system failure.

RADIO FLEETMAP

The radio fleetmap identifies the trunked talkgroups and
non-trunked conventional channels utilized within the 800
MHz CCCS.

Talkgroups and conventional channels shall be used as
outlined in this handbook.

The following talkgroups and conventional channels are
programmed into law enforcement radios. A zone number
will always precede the talkgroup/channel name.

All talkgroups and channels common to law, fire, lifeguard
and public works radios have a zone number and letter
preceding the name. These are found in zones 8 through 13.
The phonetic identifier is always used when pronouncing the
talkgroup or channel name. For example, channel “12-A” is
pronounced “Twelve Alpha.”

Zone 1 - This is the "agency specific zone" and contains
those talkgroups and channels designated by the department
in one zone for operational convenience. At a minimum, the
department specific talkgroups and channels (such as Green,
Pink) are found in Zone 1.

The GREEN-1 talkgroup is always in Zone 1, position 1.
The RED talkgroup is always in Zone 1, position 16. Each
Green talkgroup and talkaround channel is agency specific
and unique to that department. In other words, an Anaheim
Police radio selected to Green-1 will not communicate with
a Brea Police radio selected to their Green-1 talkgroup.

10

Green - Dispatch and day-to-day operations.
Green-1:
Green-2: Tactical used per department policy.
Green-3:
Tactical used per department policy. This
Green-4-7: talkgroup shall also be used for same agency
Green-TA: unit-to-unit communications when talkaround
is not feasible.

Only available to specific agencies and used
per department policy.

Pink - One talkgroup, designated PINK, is assigned to each
city and utilized for common communications between that
city’s law enforcement, fire service, lifeguard/marine safety
and public works departments. Each Pink talkgroup is city
specific and unique to that city. Communications can not
occur between other cities on the Pink talkgroup. The Pink
talkgroup is designated 1C in all fire service radios except
Santa Ana, which is 1E. The Fire Authority and Sheriff-
Coroner units do not have a Pink talkgroup in their radios.

Agency Specific - The remainder of the talkgroups and
channels in Zone 1 was selected by each department and are
those that will be most used in normal day-to-day
operations. Talkgroups and channels native to another Zone
will be found in both locations. For example, if an agency
has placed Orange North in Zone 1, it will also appear in
Zone 2 with the other Orange talkgroups.

Zone 2 (Orange) - Nine talkgroups for common law
enforcement communications shared among all law
enforcement portable and mobile radios, dispatch centers
and Control One. The Orange talkgroups are utilized for
coordination of incidents normally handled by patrol, and
not for surveillance type activity. These talkgroups may
also be used when communications with the department
dispatch center are necessary, and the unit is out of range of
their local cell, or when communicating with different law
enforcement agencies.

ORANGE NORTH and ORANGE SOUTH can be utilized
at any time. All other Orange talkgroups are reserved for
special assignment and emergency coordination only. The
assignment of these talkgroups is coordinated through
Control One.

Zone 12 & 13 (International Tactical); Zone 14
CLEMARS - ITAC and CLEMARS channels are to be used
for coordination activities between different agencies in a
mutual aid situation, or emergency activities of a single
agency. The established State Mutual Aid Radio System
priority use levels, described below, apply. When a higher
priority of use is required, all lower priority use must cease
in any area where interference could occur. The levels are:

PRIORITY 1:
Disaster and extreme emergency operations for mutual aid
and interagency communications.

PRIORITY 2:
Emergency or urgent operations involving imminent safety
of life or protection of property.

PRIORITY 3:
Special event control activities, such as a planned event
involving the participation of two or more agencies.

PRIORITY 4:
Drills, tests, and exercises.

All communications on the ITAC and CLEMARS channels
will be conducted in “clear text” using the English language.
Units operating on these channels are to include their agency
name in the unit identification (example: “San Diego Fire
Engine 22, Anaheim Police Unit 26321”).

25

Zone 12 (International Tactical) - Five conventional
channels designated by the FCC on a nationwide basis for
public safety mutual aid communications. Canada and
Mexico adopted the same channels that allow mutual aid
communications with properly equipped out-of-county, out-
of-state and out-of-country units.

One channel has been designated a calling channel (ICALL)
and the remaining four channels are for tactical operations
(ITAC1 through ITAC4). The Calling Channel (ICALL RP)
is used to hail the designated county point of contact. In
Orange County, Control One is the designated point of
contact.

The individual ITAC repeaters in Zone 12 (12B, 12C, 12D,
12E) must be activated by Control One before use.

12A ICALL-RP Calling Channel

26

Zone 13 (International Tactical) -The following ITAC
repeaters use a PL tone that is specific to Orange County
radios only.

The Orange County Public Safety radio user may operate on
these channels without any assistance from Control One.

If communications must occur between non Orange County
radios, Control One must be contacted so that the
international PL tone can be turned on, allowing out of area
units access to these repeater sites.

Zone 14 (CLEMARS Channels) – The California Law
Enforcement Mutual Aid Radio System is provided and
managed by the State Office of Emergency Services. This is
a common frequency available statewide for mutual aid
communications among authorized Law Enforcement
agencies. Orange County Law Enforcement radios contain
two modes that may be selected, repeater or talkaround. The
repeater mode is normally disabled until needed. Contact
Control One to enable the CLEMARS repeater.

utilized by the agency.

Zone 16 (Red)
This zone contains the Red talkgroup in every position of
Zone 16 allowing immediate access to the Red talkgroup
when necessary. The Red talkgroup is shared among all law
enforcement departments countywide for emergency
coordination and informational broadcasts. Every mobile
and dispatch center has a dedicated receiver for continuous
monitoring of this talkgroup. All mobiles and dispatch
centers shall monitor the RED talkgroup at all times.
Control One shall use the RED talkgroup for the
dissemination of countywide broadcasts. Field units may
select the RED talkgroup for direct contact with Control
One when reporting such incidents as pursuits, shootings,
urgent assistance required or other extraordinary
emergencies. The RED talkgroup operates on the
Countywide/Laguna cells and is not encrypted.

28

DISPATCH CENTER TALKGROUPS
DSP-DSP - A single talkgroup shared by each dispatch
center. This talkgroup provides common communications
between all dispatch centers, and is for their exclusive use.
Field radio equipment does not have or use this talkgroup.
All dispatch centers shall monitor this talkgroup at all times.
DSP-DSP shall be the primary communications method for
providing major incident status and important informational
broadcasts that are intended for multiple dispatch centers. It
shall not be used for routine and/or single agency contacts.
AIRCALL - A single talkgroup assigned to each law and
fire dispatch center, as well as each law and fire helicopter.
It is used as an aircraft calling talkgroup. Field radio
equipment (with the exception of air units) does not have or
use this talkgroup.

OPERATING PROCEDURES

In order to achieve maximum efficiency from the trunked
radio system, operating procedures have been established for
all radio users. The practice of proper day-to-day radio
procedures will also make emergency radio procedures
automatic and reduce confusion in times of stress.

Operating Protocols - All communications regardless of
nature shall be restricted to the minimum practical
transmission time. Unit-to-unit tactical communications,
when feasible, shall be conducted on the appropriate
talkaround channel. This will help in reducing the potential
of radio busy signals on the trunked system.

Any transmission longer than 30 seconds shall be broken up
at 30 second intervals. This allows the person copying to
assure you that the message is being received and to ask for
a repeat of any portion of the message that was missed, and
it allows any other unit to transmit emergency traffic
without a long delay. Pronounce words distinctly and rather
slowly. The normal dispatch rate is about 40 to 60 words
per minute. The voice should be as emotionless as possible
on the air regardless of the situation. Emotion tends to
distort the voice and render it unintelligible. Attempt to
make your voice a regular monotone. Emergency messages
require no expression, but a high degree of intelligibility.
Use of radio code facilities both brevity and clarity. Be
familiar with the Official Radio Code utilized within Orange
County.

39

The 800 MHz CCCS is licensed by the Federal
Communications Commission (FCC) for official
communications of the Orange County public safety
agencies participating in the system. Radio users shall be
impersonal on the air. Never address the person receiving
your message by name or use the term “I” in referring to
yourself. Do not try to be humorous on the air, it never
sounds as funny as you think. Do not let anger or
impatience be heard in your voice. The FCC forbids
profanity and any superfluous or extraneous transmissions.
The full and complete assigned station and unit number
designation shall be used at all times.

Descriptions – The description of any person should contain
as much of the following information that is known:

1. Name of person 8. Color of hair
Color of eyes
2. Sex 9. Complexion
Physical imperfections
3. Race 10. Clothing from head down
Any other information
4. Age 11.

5. Date of birth 12.

6. Height 13.

7. Weight

The description of a vehicle should contain the following
information:

1. Color(s) of vehicle 5. License number

2. Year 6. State of issue

3. Make 7. Any other information

4. Model and body style

40

Procedure for Dispatch Center Initiating a Radio Call -
When a dispatch center wishes to contact a field unit, the
dispatcher shall state the name of the unit followed by the
dispatch center name/station number. For example, “31213,
Station 31.” The unit being called shall answer with their
own radio unit number.

Procedure for Field Unit Initiating a Radio Call - When a
unit wishes to contact the dispatch center, the unit shall state
the name of the dispatch center followed by their unit
number. For example, “Station 24, 24313.” The dispatch
center shall respond with the unit number (in case several
units were calling at once, this response indicates which unit
is being acknowledged and informs that specific unit to
continue with their message). When a unit wishes to contact
another unit, the unit shall make contact using the same
format. For example, if unit 24313 wanted to call 24312,
the unit would state “24312, 24313.” The unit being called
shall answer with their own radio unit number.

Procedure When Not On Primary Talkgroup - When a
field unit or dispatch center makes a call that is not the users
primary talkgroup or conventional channel, the name of the
talkgroup or conventional channel shall also be transmitted.
For example, “Control One, 36312 on Tan-Call” or “Station
36, 23034 on Orange North.”

41

Procedure for Contacting Other Public Safety Agencies -
The 800 MHz CCCS allows any radio system user the
ability to communicate directly with any other radio system
user. Internal city/agency policy shall be established for
Intra-agency communications. When it is necessary to
contact a field unit or dispatch center outside your
city/agency, the field unit may contact Control One on
TAN-CALL. The reporting of emergency or hazardous
situations can be relayed by Control One to the appropriate
agency. If it is necessary for the field unit to communicate
directly with another agency dispatch center and/or field
unit, Control One shall notify the appropriate agency and
have the units meet on an appropriate talkgroup. Law
enforcement will be directed to ORANGE NORTH or
ORANGE SOUTH. Personnel from different disciplines
will be directed to TAN NORTH or TAN SOUTH.

Law Communications - The communications needs for law
enforcement will range from simple to complex. Day-to-
day operations may be handled on as few as two or three
talkgroups/channels (dispatch, trunked tactical and
conventional tactical). A larger incident, such as an aircraft
crash, large-scale evacuation or civil unrest may need more
talkgroups and/or conventional channels to efficiently
handle the communications needs.

The following protocol, established by the Orange County
Chiefs' of Police and Sheriff's Association, is designed to
improve incident operations and safety through a
standardized approach to organizing communications for
day-to-day and expanded incidents.

42

 Dispatch

The dispatch talkgroup is used to dispatch calls for service
and coordinate the day-to-day activities of each agency.
Lengthy transmissions and specific tactical operations will
be conducted on an appropriate tactical talkgroup/channel.

 Tactical

The tactical talkgroup/channel is used for tactical
communications between field units and the dispatch center
or between field units and other field units. On larger
incidents, separate and unique tactical talkgroups and/or
conventional channels shall be established for specific
functions. Agency specific assignments using agency
specific talkgroups/channels are made by the local dispatch
center. Assignments using countywide talkgroups/channels
are made by Control One as requested by the Incident
Commander or designee.

Unit-to-unit tactical communications shall always be
conducted on the trunked talkgroup or conventional channel
as outlined below:

1) on the appropriate agency specific talkgroup
(GREEN-3, GREEN-2, GREEN-4, etc.)

2) on the appropriate agency specific talkaround
channel
(GREEN-TA)

3) on the appropriate common law talkgroup
(ORANGE-N or ORANGE-S, GRAY-N or
GRAY-S, BLACK-N or BLACK-S)

4) on the appropriate interoperable talkgroup
(PINK, TAN-N or TAN-S)

43

OFFICIAL RADIO CODE

The use of radio code facilitates brevity and clarity. The
County of Orange “Official Radio Code” has been
established to ensure common radio terminology for all
radio system users, regardless of discipline. Only the
official radio code listed shall be utilized when
communicating on the 800 MHz CCCS.

When communicating with personnel from other disciplines
on the common talkgroups and channels (such as the Tan
talkgroups), the use of clear text (no radio code) is
recommended. This will facilitate the communications with
personnel from other disciplines who are not familiar with
all radio codes.
