SmartNet Trunked System Overview
tor
The City ot San Bernardino
The County of San Bernardino ("COUNTY") and the City of San Bernardino ("CITY") have designed
a SmartNet wide-area trunked communications system for the City of San Bernardino, The
trunked system design inciudes a two site. 10 channel simulcast system with 3 bidirectional RF
amplifiers; a single site. 5 channel repeater system; and. an eieven site SCADA system located at
each fire station,
The 10 channel trunked simulcast system will have repeaters located at Jurupa and Little Sunset
with directional antennas pointed toward the City of San Bernardino, In order to provide RF
coverage in the area behind Shandin Hill. a stand-alone 5 channel trunked SmartWorks repeater
system will be located at the Kendall Fire Station, three bidirectional amplifiers will also be used to
provide RF penetration into the large facilities of City Hall, the Carousel Mall and the inland
Center Mall.
System Operation and Redundancy Modes
The following tabie lists the modes of operation of the City of San Bernardino's 800 Mhz trunked
radio system, Mode 1 is the normal. day to day. mode of operation, Each higher level provides

failure to the System Administrator.
8. Wide Area Failsoft - Site 1 & 2 operating as dual site simulcast, non-trunked,
conventional repeat. with FailsoftlD.
9. Local Area Failsoft - The Primary Site reverts to local Failsoft. with 'in-cabinet audio
repeat', The secondary site Is automatically disabled,
10. Forced Manual Failsoft - This mode assumes that the primary and/or the secondary
sites are stili operational. but the prime site controller or microwaves systems are down
between Little Mountain and both radio sites, In the event that Local Are Failsoft from
the Primary Site is not automatically invoked. or there Is a problem with the Primary Site
system in Failsoft, the Secondary Site can be forced to go into Local Area Failsoft, This
condition can be triggered either by radio or wirellne signalling, and will at the same
time disable the Primary Site as well as the Prime Site Controller,
Note 2: The Little Sunset radio site is identified as the Primary Site, The Jurupa radio site is
Identified as the Secondary Site, For the purposes of assigning priorities, and to prevent
each site from acting autonomously. each site is assigned a functional role with an
associated priority, The priority determines the active role of the radio site In each
operational mode,
Note 3: Prime site controller fully operational; Microwave path from City Hall to Littlme Mountain is
operational.
Note 4: The System Manager diagnoses that a major system failure has occured preventing
'Normal' trunked operation. 'Wide Area Failsoft.. or 'Local Area Failsoft', The System
Manager initiates a manual selection of Mode 6 to enable 'Local Area Failsoft' at
Jurupa. The action of selection of Mode 6 aiso disables the prime site controller and all
associated infrastructure equipment that might interfere with Mode 6 and cause
harmefull interaction if the failed micowave paths or equipment were to return to normal
operation, It is the responsibility of the System Manager to determine that the system
failures have been eliminated. system alarms are reset. and that the system can be
returned to Mode 1 or Mode 2.

Note 5: Shared resources include services and frequencies that can be assigned in the case of a
major system failure and the need for short-term emergency backup, Coordination
between the County of San Bernardino 800 Mhz Administration and Management
Unlt(SBCO/SAMU) can provide ievels of interoperability on the Valley and Mountain
systems, The City Dispatch also includes a single Fire Dispatch Console and Police
Dispatch Console connected directly to the County Backbone for emergencies. as well
as inter-agency inter-operability, SB County resources may also include temporary
portable trunked repeater system. and temporary portable dispatch facilities, The level
of support available will be dependent upon need. the extent of the emergency. and
the coordinated efforts between SBCO/SAMU, and are intended to provide for the
public safety in those rare cases of wide area disaster.
The transition from a lower mode to a higher mode will be automatic. as will the return to a lower
mode when system alarms are cleared. However, some modes will require direct action by
dispatch or the System Manager to clear specific types of alarms, or to initiate manual backup
modes,
The functional details of switching between Modes will developed by COUNTY engineering and
delivered for review and approval as part of the Design Document. a contract deliverable, A
part of the Design Document will Include specific details and flowcharting that will direct the City
on how to identify system failures, mode changes. and the necessary steps to return the system to
Mode_l operation,
Fire Station Control
A SCADA sub-system will be incorporated on the simulcast trunked system to provide remote
control of each of the eleven City fire station garage doors, station alerting, audio paging. and
miscellaneous control functions, This sub-system will replace the existing Motorola INTRAC system,
The City's CentraCom II console will be interconnected to the trunked system's prime site
controller located on Little Mountain over the existing microwave radio system, In addition to the
prime site controller. Little Mountain will also be the location of 10 Digitac comparators, the
simulcast distribution amplifier, digital channel banks and data modems,

Trunking Description
Motorola trunking is a microprocessor based technology that automates the channel selection
process for users, maximizing frequency efficiency. system control and administration. and ease of
operation,
Motorola trunking utilizes a control channel in each system, which provides the focal point
between the system's Infrastructure and its radio units, The Central Controller coordinates the
systems repeater resources, and uses the control channel to assign voice channels and control
radios,
The system's field units (mobiies, portables. control stations) siiently monitor an outbound stream of
data transmitted by the control channel for system updates and voice channel assignments
pertaining to their talkgroups, Radios needing to initiate a conversation send a request for service
to the Central Controller by transmitting a data burst over the designated control channel
repeater. This data burst from a field unit to the controller is called an Inbound Signalling Word
(ISW). Once the received data Is interpreted by the controller. an avaiiable voice channel is
assigned for the conversation. The controller uses the control channel repeater to send a data
burst to the field unit initiating the call. and to all the other radios specified in the data contained
in the ISW. A data burst from the controller to fieid units is called an Outbound Signaling Word
(OSW) ,
The ISW and OSW are digital signalling words. Under normal conditions. this signalling is
completed in about 1/4 of a second, The Information is easiiy reformatted by controllers to
provide enhanced system features. The Infonnafion in the ISW is translated by the Central
Controller to provide enhanced system features, Motorola's dedicated control channel
approach has proved to be more reliable and efficient than other trunklng methods,
Field units specified for Inclusion in a call wiil use the voice channel for the duration of the call,
Upon ten-nination of the conversation, the voice channel becomes avaiiable to any other users
on the system.
Phase III: City of San Bernardino 800 MHZ Trunked Backbone - System Overview Page 4
94 327
Access Features
Access features are defined as features which happen automatically through the SMARTNET 11
software in the controller. They provide many of the benefits of trunking, particularly convenience
and ease of use.
Automatic retry
Automatic retry is a feature which eliminates the need for users to repeatedly press their PT-r
switch to obtain a voice channel assignment In adverse signalling conditions, a field unit's voice
channel request may not be received by the system controller on the first attempl During the four
seconds that follow the depression of the PTT switch, the radios wili automatically send the
channel request sixteen times, until acknowledged by the controller. The sixteen attempts use a
random transmission timing aigorithm, which eliminates the possibility of contention on the control
channe!.
Queueing
When all voice channels are occupied with conversations, radios requesting service are placed in
a queue, with the first in line to request a voice channel the first to receive a voice channel
assignment (see Priority Levels and Emergency for exceptions).
Priority Levels
SMARTNET R offers eight levels of priority as a standard feature. The highest ievel of priority is
Emergency. Tie second level of priority if typically reserved for tactical operations. The remaining
leveis are assignable according to operational requirements. Priority levels only take effect when
all voice channels are in use. Call requests are received and queued according to priority leveis.
Priority levels are assignabie at both the individual and taikgroup level, with the highest level of
priority taking being used when talkgroup and individual levels are not the same. Priority levels
are assignable through the System Manager T ermina!.
Callback
When all voice channels are busy, a field unit Initiating a callis placed in queue. When a channel
becomes available the next radio In the queue is sent a Talk Permit Tone, alerting the radio user
that a channel Is available for a conversation.
Phase III: City of San Bernardino 800 MHZ Trunked Backbone - System Overview Page 5
94 327
Talk 19d1.ibi3r2~
If a radio In the busy queue presses the PTI'switch before a voice channel has been assigned, a
busy tone is emitted from the radio. The busy tone wili persist until the user releases the PTT switch,
unless a voice channel Is assigned.
OIJt of Range Tone
When a radio Is out of the system's coverage area, if the user presses the PTT switch, the radio will
emit an Out of Range tone. This can occur any time the radio ceases to receive the systems OSW
from the controller.
Recent User Priority
'ne recent user priority feature heips to preserve continuity In communication, by minimizing wait
times between questions and answers on a busy system. This is accomplished through allowing
users requiring to re-Inltiate a previous conversation are placed in queue, ahead of talkgroups of
the same priority. Talkgroups engaged in conversations receive priority system access for 10
seconds following the last talkgroup transmission.
Misdirected Mobile Protection
Misdirected mobile protection is a feature that ensures that mobiles do not mistakenly participate
in conversations of other talkgroups. This is performed by transmitting the ID of the talkgroup
assigned to a voice channel in the subaudible data stream during the conversation. if a radio
accidentally locks onto the incorrect voice channel, it will not recognize the data stream ID. and
wili revert to the control channel frequency.
ContintJolJs Assignment IJpdating
Field units entering service or the RF coverage area during an ongoing conversation within their
talkgroup are immediately directed to that voice channel to allow participation in that
conversation. This Is accomplished through the control channel continually sending channel
assignment updates. Channel assignments occur serially.

Talkgroup Calls
The talkgroup call is the most basic type of call available on a SMARTNET 11 trunked system. It
represents regular dispatch communications between multiple users. A system can
accommodate up to 4000 talkgroups (2000 if Priority Monitor Is In operation).
Automatic Unit Registraflon
When radio users choose to operate In a different M&group, the user changes the setting on the
radio's talkgroup selector switch or button. When a taikgroup change is made by the radio user,
the radio unit's ID and new talkgroup ID are automatically transmitted to the trunking controller.
AnnolJncement Group Call
Announcement Group Call permits a radio to transmit simultaneously to numerous talkgroups.
The Announcement Group Call may be set one of two ways. The Central Controller may be
programmed to wait while talkgroups finish calls In progress, which allows transmitting radios to
hear the entire announcement. Alternatively, the Announcement Group Call may be set to
interrupt talkgroup calls in progress, not waiting for transmitting radios to dekey. Upon dekeying,
the interrupted transmitting radios are directed to the announcement call in progress.
Announcement Group Call uses message trunking, allowing those receiving the call to talkback
Into the announcement group.
System Call
Designated users, who are propperly equipped and field programmed, wili have access to the
System Call feature, which allows simultaneous transmission to every radio user on the system,
regardless of talkgroup boundaries. When a System Call is piaced, the user initiating the call waits
until system users in other conversations have dekeyed. Other system users attempting to initiate
calls wili receive system busy indications until to System Call is completed.
Radio users engaged In emergency or telephone communications will not be affected by the
System Call until they return to regular talkgroup communications, at which time they wili join the
System Call in progress. When the System Call radio user dekeys, the system wili return to regular
dispatch operations.
Phase III: City of San Bernardino BOO MHZ Trunked Backbone - System Overview Page 7
.;4 327.
Priority Monitor
Priority Monitor allows properly equipped field units to enter several talkgroups into a Priority
Monitor scan list. Two talkgroups are selected as first and second priority talkgroups. When idle
the field unit will scan the control channel for activity directed at any of the talkgroups in the scan
list. If a talkgroup is assigned a voice channel, the radio follows the assignment and can
participate in the conversation as a member of the talkgroup, regardless of Its currently selected
tatkgroup.
Even while engaged In talkgroup communications, the radio continues to scan the low speed
data stream on the voice channel, for activity directed at one of the two Priority Talkgroups.
Activity on one of the two Priority T alkgroups will cause a radio to leave a non-priority
conversation, unless Involved in secure communications.
Field units can be programmed to set their own Priority Talkgroups.
Emergency Alarm & Call
An Emergency Alarm or Emergency Call is a call Initiated by depressing the dedicated
emergency button on a properly equipped field unit. Many public safety users require a system
which is equipped with the Emergency feature. Emergency is the highest level of priority
available on SMARTNET II systems. The Emergency Alarm is a burst of data sent over the control
channel to a trunked terminal which is properly programmed.
Field units may initiate Emergency Calls, to establish emergency communications. An emergency
call is sent over the control channel when the radio is in Emergency mode and the M is
depressed. A visual and audible alert are sent to a properly equipped trunking terminal (I.e. SiP or
SWII), and a voice channel is assigned for the talkgroup of the field unit initiating the emergency
for a pre-determined amount of time (set by the System Management Ten-nlnal). When the
system is busy, the radio is assigned a channel using the "Top of Queue" mode, providing that
radio with the highest priority in the system. When a channel becomes available, It will be
assigned to the Emergency Call before allowing access to any other radios waiting In the queue
(except for other radios in the emergency mode, who placed their emergency calls prior to the
one in question). While any radio is in the "Top of Queue" mode waiting channel assignment, all
system trunked repeater hang times will automatically be set to zero, providing fastest system
access possible.

94 327.
Selective Calling
Two different types of Selective Calling are available on SMARTNET H trunked systems. Both call
types are sent over the control channel, and can reach any radio registered on the system as the
initiating unit. Access to these features is determined both by the field units' programming and by
authorization via the System Manager Terminal.
Call Alert
A Call Alert is a tone page sent over the control channel to a radio whose user is sought. All
SMARTNET II radios have the capability to decode a Call Alert. The receiving unit emits alert
tones, and if properly equipped display and stow the unit ID of the sending unil Tie radio initiating
the call alert call receives feedback indicating whether or not the Call Alert was received.
Once received, the Call Alert page continues to sound on the receiving radio unit until
acknowledged by pressing the M switch. When the alerted user responds by pressing the PTr
switch, transmission will occur in the user selected talkgroup. Properly equipped radios may also
activate the ham and / or lights of the users vehicle to indicate that a Call Alert page has been
received. When users not equipped with portable radios must frequently leave their vehicles, this
provides a quick method of communicating with them.
Private Conversation
Private conversation allows properly equipped radios operating on the same system to establish
unit-to-unit communications. The sender enters into the Private Conversation mode, enters the
target unit's ID on a keypad, and presses the PTT switch to initiate the call. The target radio
receives an audible indication that the conversation being received is a private conversation,
and by pressing the PTI' switch enters into the private conversation with the sending radio. Private
conversations cannot be received by a unit already engaged in a talkgroup call.
While no other radios operating on the system will be directed to the voice channel In a private
conversation, this does not insure protection against unauthorized monitoring. A secure voice
channel is the only way to preclude unauthorized monitoring from outside the system.
Display radios allow users to scroll through a preprogrammed list of target radios for selective
signalling, and some will store and display the sending unit's iD when receiving a selective call.

Motorola's SMARTNET 11 trunking systems are fauit tolerant and win continue to operate as a full
featured, advanced trunking system if a single point hardware or software failure occurs.
Motoroia's SMARTNET 11 systems have many features built in to provide the level of reliability
required by a public safety user. Some of these features are outlined in the following section:
Multiple Channels
There is a degree of reliability built Into a trunking system by the fact that It contains multiple
channels, with dynamic channel assigmcnlln the event that a repeater or repeaters fail, an alarm
is sent to the system manager, and trunking continues, with the failed repeater(s) never being
assigned as a voice channel. If the failed repeater is the control channel, a different control
channel takes over. Field units scan for the control channel, and in the event of its failure would
automaticaily locate the new control channel.
Back Up Control Channels
Anyone of four channels on a trunked radio system may be the control channel. Control
channel assignment rotates among these four channels on a dally basis. In the event that the
control channel fails, one of the other eligible channels takes over as control channel.
Failsoft
Failsoft Is a standard feature on all Motorola trunked systems. To ensure continued
communications, even in the event of catastrophic system failure, such as failure of the Central
Controller and the redundant Central Controller, failure of all four control channels, or failure of all
voice channels, a Motorola trunked system will go Into the failsoft mode. The system goes into
failsoft within 10 seconds of system failure. When in failsoft radios operate as they would on a
conventional repeater system. A subaudible tone is continuously sent out by the system repeaters
to let them know that the system is in failsoft. This ensures that field units will not go Into the failsoft
when out of range of the system. Radio users are made aware that the system has gone into
failsoft by a low level, audible alert tone sent by the repeaters every 10 seconds.
Phase III: City of San Bernardino BOO MHZ Trunked Backbone - System Overview Page 10
94 327
The channel that will be used when in the faflsoft mode is predetermined through programming.
Talkgroup privacy will be lost in a large, heavily used system. Failsoft assignments may be made
by fleet or by talkgroup.
System Self Diagnostics
The Centrai Controller has the ability to diagnose system problems. It continually performs Central
Controller integrity, repeater receiver interference and transmitter Interference checks. The results
of these checks can activate visual and audible alarms at the Central Controller site. Relay
contacts at the backplane of the Centrai Controller are provided for this purpose. The System
Manager Terminal prints out error messages as they are received via a Central Controller port.
Optionally, every 24 hours, the following checks are performed: tone detectors on the receiver
interface board (RIB), ROMs and EPROMs on all Central Controller boards, and memory and AID
circuitry on the inbound receiver board (lRB).
Receiver Interference Shutdown
Receiver interference occurs when an unauthorized signal Is received on a repeater. It may be
caused by a mobile on another system with similar frequencies enters the coverage area of the
SMARTNET H system. In order to prevent disruption of communications, the Central Controller swill
shut down the repeater when it detects an undesired carrier for longer than the specified time
out period.
Transmitter Power Failure Shutdown
The Central Controller can detect a ioss or decrease In the transmitter output power. If the output
of one of the repeaters drops beiow a threshoid level (perceptible to system users) the Centrai
Controller will not assign that repeater as a voice channel, and will send an error message to the
System Management Terminal. The central can also detect an excess of reverse power (typically
due to antenna fauit).

COUNTY will interface CITY supplied logging recorder
equipment. Logging Recorders required to record trunked talk
group audio must be located at the CEB site. All "de-
trunking" of trunked Talkgroup audio is done in the logging
recorder interface of the trunked central electronics bank.
11. BI - DIRECTIONAL AMPLIFIERS (BDA)
The specific design parameters for installation and operation
of the Bi-Directional amplifiers has not been identified. In
view of the CITY's public safety providers need for radio
coverage within the City Hall, the Carousel Mall and Inland
Center Mall, these locations will require individual analysis.
A basic overview indicates that a single BOA will address the
coverage concerns at City Hall. However, the two malls will
probably require 2 BOA's each due to their size and
construction. Specific design cannot occur until the BOA's
are available. The two mall locations will require field
engineering with assistance from city staff to maximize
coverage in critical operational areas.
