Trunked Radio System

ECP-3406 page 3

Project 25

Interoperable digital radio system standard

Intended for all public safety LMR bands

(VHF, UHF, and 800 MHz)

Developed Jointly by:

TIA

Association of Public-Safety Communications Officials (APCO)
National Association of State Telecommunications Directors

(NASTD)

Various agencies of the Federal government (FED) in the early

90’s to improve spectral efficiencies

TIA/EIA Standard in 1999. Under TIA/EIA-102

ECP-3406 page 4

Project 25 Benefits

Key benefits sought by the user community:

– Competitive procurement of equipment
– Interoperability of equipment
– Spectrum efficiency
– User-friendly operation equivalent to today's public

safety equipment and common across all bands,
system configurations, services, and
manufacturers

ECP-3406 page 5

* SAFETY ITEMS *

DO NOT...operate the mobile radio when someone is outside the vehicle

within two feet of the antenna. This is a recommendation from OSHA
that applies to any type of radio transmitter such as a cellular

telephone, CB radio, our old radio system, or our new radios.

DO NOT...operate the mobile radio if any of the antenna connectors are

loose. This is a basic safety precaution. If the antenna cable or
connectors are loose, please place a service call for repair.

DO NOT...operate the mobile radio near or in an area where blasting is

taking place. Anyone using radio controlled explosives must post
signs. If you see a caution sign about blasting in the area, you must

turn your radio off. This applies to any radio equipment capable of

transmitting: phones, CBs, etc.

DO NOT...operate the mobile radio in an explosive atmosphere. The

radio is an electrical device with switches that can cause an explosion
in an explosive atmosphere. If you can operate your vehicle or any
power tools, it is safe to use the radio.

ECP-3406 page 6

Operating Rules and Regulations

The Federal Communications Commission sets all rules for two-

way radio use. All users of two-way radio equipment should be

familiar with these basic rule requirements.

It is a violation of FCC rules to interrupt any distress or

emergency message
Any use of profane or obscene language is prohibited
It is against the law to send false call letters or a false distress

or emergency message
All messages must be brief and limited to the business need
It is a violation of FCC rules to send personal messages,

unless in an emergency
The FCC requires that radio systems be identified by use of

the assigned Call Letters – the radio system does this

automatically

ECP-3406 page 8

Why Trunking?

Improves spectral efficiency
Relieves the user from managing the channel
Encourages cross agency / shared communications
Establishes communications privacy
Encourages private communications
Discourages eavesdropping by scanners

Establishes “queuing” rather than “waiting”

Enables priority use during busy times

ECP-3406 page 11

Multisite - What the Radios Do

Units inform the System of their location:

Each time the Radio is powered up

Each time a System selection is made
Each time a Group selection is made

When Radio detects a high bit error rate on the Control Channel,

Radio will look for another site (algorithm programmed in radio),
Automatically switches to new site when criteria met

Group Call Scanning

The radio is able to monitor multiple groups, but the radio can only receive

one group at a time

The radio can scan only those groups on a “Scan List”

This list can be programmed by the user, or

The list may be directly programmed into the radio by the Network

Administrator

Turning the Scan function On or Off can be:

Fixed in programming by the Network Administrator, or

Controlled by the radio user

Radio can have up to two “Priority Talk Groups” designated

Priority 1 Talk Group

Priority 2 Talk Group

Priority Talk Groups can be assigned by the radio user, or they might be

fixed in the programming by the Network Administrator

The radio will be extracted from listening to a scanned call if a call with a

higher priority is received

Status & Message Operations

STATUS operation allows a pre-programmed status condition to

be transmitted to a P25 trunked tower site

MESSAGE operation allows a pre-programmed text message to

be transmitted to a P25 trunked tower site

Each STATUS and MESSAGE is assigned an ID that is cross-

referenced to a determined condition (ie., Off Duty, In Service,

Transporting, or some similar message)

The messages are routed from the tower site to a specific

dispatch console (or to several specific consoles) that have been
pre-designated to receive that particular message (based on the

assigned ID number)

Each STATUS condition message and each MESSAGE text is pre-

programmed by the system administrator – individual radio

operators cannot enter their own messages as “text” entries

nor can they choose which console(s) receive the message

ECP-3406 page 51
