What is Trunking? Conventional Trunking A trunking radio system differs from a conventional radio system in the way it shares channels between radios Conventional Trunking 1 channel to one or more groups of user Employs no logic in call handling Usually 1 call to 1 channel (2 to 1 with MOTOTRBO digital) A trunking system shares a pool of channels for a large number of users (talkgroups) Automatically assigns available channel to requesting user Lowers probability that calls will be blocked because an open channel will be found easier Allows fewer channels to support larger amounts of users

Channels dedicated to talkgroups Channels Shared by Talkgroups Convenmtional vs. Trunking Conventional Channels dedicated to talkgroups Trunking Channels Shared by Talkgroups Channel Channels Channel More efficient use of channels Higher traffic density Simple user operation automatic channel selection, call queuing Channel Low complexity, low cost

Repeater Alarm Reporting RDAC –Remote, Diagnotics and Control Motorola provides a software application that allows a system administrator the ability to monitor and control repeaters within the system (analog or digital) The following features are available: Repeater Diagnostics Read Enabled/Disabled Status Read Analog/Digital Status Read Wide or Local Area Status Read Transmit Power Status Read Available Channels Read Inbound RSSI Read IPv4 Address and UDP Port Repeater Control Change Status „Active“ or „Disabled“ Change Channels Change Power Level Reset Repeater Repeater Interrupt Repeater Alarm Reporting Detect and Report Receiver Lock Detect Failure Detect and Report Transmitter Lock Detect Failure Detect and Report Overheating Detect and Report AC Power Supply Failure Detect and Report Main Fan Failure CPS Programmable Pins Description Major Alarm (Locked State) This output pin is used to report a major alarm has happened 3 times, been reset three times, and the repeater is in now locked state. Minor Alarm This output pin is used to report minor alarm(s) is happening on the repeater. Repeater Disable: Asserting this input pin triggers the repeater to enter disabled state. In this state, the repeater can not execute repeat functions. Releasing this input pin will revert the repeater back to enabled state where the repeaters can start repeating calls. Tx Power Level High: Asserting this input pin triggers the repeater to change the TX power level to be high. Releasing this input pin will revert the repeater back to TX low level low. Repeater Knockdown Asserting this input pin triggers the repeater to temporarily enter Repeat Path Disable Mode. In this mode, the repeater’s transmitter will only be enabled by the external PTT and the audio source will be the Tx Audio Input pin. Releasing this input pin will revert the repeater back to Normal Mode where the repeaters transmitter can be activated by a qualified RF signal on the receive frequency. *Note that this pin will works the same as Repeater Disable control since repeater knockdown is not supported in digital mode. Channel Change There are up to 4 pins that can be configured and used for channel change. The repeater can support up to 16 channels. Asserting this input pin represents 1. Releasing this input pin represents 0. 0000 represents first channel, 1111 represent the last channel. Operates over an IP network or locally via USB or GPIO connection RDAC can only communicate with one wide area system at a time 8

RDAC User Interface Main interface Configuration screen Diagnostics Screen Control screen Upgrading Repeaters for RDAC There is only one condition when a hardware upgrade may be required for legacy repeaters If an end user requires the following alarms: Detect and Report AC Power Supply Failure Detect and Report Main Fan Failure In this instance a small board will need to be added to repeaters that were purchased prior to the 1.4 release Note: Choosing not to do the hardware upgrade will still permit access to all other RDAC functions in legacy repeaters! 9 9

Is only the home for inactive radios Rest Slot: the key to Capacity Plus Acts as a “dynamic home slot” Can be any slot on the system Rest Slot will “roll” to different voice slots in the system Frequently changes during system use Rest Channel Is only the home for inactive radios A B C D F G Slot 1 Slot 2 Slot 3 Slot 4 IP Switch

How does it work? Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 Slot 6 Slot 7 A B C B C C A A B TG C Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 Slot 6 IP Switch Slot 7 Slot 8 Process is repeated over and over ensuring optimal performance!

How does it work? - Repeater All new calls always start on the Rest Slot When a call starts, the Rest Slot: Selects an idle slot to be the new Rest Slot Informs all idle subscribers to move to it Converts itself to a traffic slot Begins repeating audio to radios When a call ends on the Rest Slot: The repeater informs the radios of the new Rest Slot The radios then move to the new Rest Slot

How does it work? - Subscriber All possible Voice Slots are programmed into the subscribers Radio must “know” of the channel to utilise it Upon power up: Radio performs a passive search for Rest Slot Listens for an active rest channel If all channels are idle: A “polite” wakeup message is sent to known channels Known = programmed into radio Messages are sent one by one to each channel

Rest Slot Benefits Allows system to be “shared channel friendly” since it can still operate with interference Easier to satisfy the FCC frequency coordination requirements since protected channels aren’t required No control slot required No wasted channel capacity = LOWER SYSTEM COSTS! The “request and grant” control mechanism is removed from the equation, allowing for quicker system access time

Understanding Capacity Plus Preference Levels The repeaters in a Capacity Plus system use a metric or weighting system to determine which channel should be the next rest channel and therefore the next voice channel. For example, if there are 4 repeaters in a Capacity Plus system and the fourth repeater happens to be vulnerable to interference then you can set it’s Preference Level number to a higher value than the other 3 and it will be chosen to be the rest channel less often than others. If RF channels had the same performance, coverage and resistance to interference there would be no need for this control. But often this is not the case. There’s no point in granting equal access to the fourth repeater if it has inferior coverage (for example). Lower Preference Level numbers mean higher preference. Higher numbers mean the channel will be chosen less often as the next rest/voice channel. All the repeaters in a system may have the same value (eg all 4 repeaters could have a Preference Level of 1) or they all could be different.

Data on Voice Slots All data is sent on trunked Voice Slot Enables single repeater (2 slot) trunking Data will contend with voice calls for channel resources Recommended that data load is small to minimize voice call channel busies

Revert & Voice Slots Data on Revert AND Voice Slots The ability to offload data on Revert Slots This is data from a subscriber to an application server Example: GPS Location updates Example: Text messages to text server Server to SU data on trunked Voice Slots More efficient Radios do not have to scan Data Revert Slots Minimizes late entry scenarios for voice calls (Voice Quality of Service) Radios receive messages when idle Example: Text message from server to radio SU to SU data on Trunked Voice Slots Radio to radio text messages Note: You cannot utilize one slot for data revert and the other slot for trunking

Capacity Plus Data Revert A Capacity Plus System can be designed to have a “data subsystem” This system contains a group of dedicated repeaters that are used to offload data only They are NOT used for voice 12 repeaters can be combined to create a revert system 24 data revert slots These slots, like voice slots are programmed into the subscriber Radio subscribers move to the revert slots to send data

Do Data Revert Slots Trunk? The Data Revert Slot does not trunk Radio is programmed for all known revert slots Radio will cycle through the list for revert data transmission. If channel is busy, it will switch to the next revert channel in the list to transmit data. 

Greatly increases channel efficiency Capacity Plus Data Revert: Value Proposition Greatly increases channel efficiency Voice calls do not disrupt data More data can be offloaded on system Example: Faster GPS update periods

Understanding the subscriber revert process Subscriber cycles through it’s list of data revert slots to send its data Subscriber evaluates up to 4 data revert channels Tries to find an idle channel and TX the data Example 1 Evaluate 1st channel in list – busy Evaluate 2nd channel in list – busy Evaluate 3rd channel in list – idle Transmit data Return to trunked channels Example 2 Evaluate 1st through 4th channels – all busy Return to trunked channels and set a random hold off timer Random hold off timer expires –radio looks to send data again Evaluate 5th channel in list – idle Transmit data Return to trunked channels

Data System: Trunked Control Station Capacity Plus Systems utilise a “Trunked Mobile” control station Connects to an Application Server Always follows rest slot Returns all data ACKs to the subscribers (from application) Delivers text messages to radio system from text applications Legacy data applications still also utilise control stations Must be programmed with all known Voice Slots Sends all data on the voice slots (Rest Slot) Systems can have more than one (1) Trunked Control Station Driven by the amount of application data sent to the radio system Can be dedicated to a range of radios Example: TCS 1 can address radios 1-100, and TCS 2 can address radios 101-200

Mobile Control Stations Summary Subscriber cycles through it’s list of data revert slots to send its data Subscriber evaluates up to 4 data revert channels Tries to find an idle channel and TX the data Trunked Control Stations These stations move with the rest slot and send data to your radio fleet Data Revert Control Stations Up to 24 stations can be utilized to receive data from your radio fleet

Revert Control Station Understanding the Control Stations Trunked Control Station Application Server 101001 Revert Control Station Slot 1 Slot 1 101001 Revert Control Station Capacity Plus Rest Slot Capacity Plus Data Revert System Operation: Upon power up a radio sends its registration data to an application, this is sent on the Legacy Control Station (this operates like conventional MOTOTRBO today) The Trunked Control Station “returns the ack” to the most current rest slot

Capacity Plus Application Support Most existing 3rd party applications will be usable on Capacity Plus, however… …due to some data enhancements some slight modifications will need to be made by the developer of your application Motorola’s Text Messaging & Location Services Suites, have NOT been optimized to work with Capacity Plus

Fault Tolerance Conditions Voice Repeater Fails IP Switch fails Receive an indication on RDAC If it’s being used System remains operational Will operate with less capacity Heavily loaded systems could experience higher instances of system busies Receive an indication on RDAC If it’s being used Radios will continue to “trunk” but only on the repeater that they were on at the time of failure All repeaters revert to a “2 slot trunked” configuration Radio distribution will impact system performance All Channels are busy Radio will ‘bonk’ Display radios will exhibit “system busy” string

System Planing & Programming

System Planning: Channel Frequencies Is this a new system? Are the frequencies being used new? If yes, have propagation studies been completed Are there any interference issues that need to be addressed?

System Planning: Channel Loading Considerations How many users will be on the system? Will the system add new users in the future? Applies to voice and data users System planners should design the system to accommodate future users that may be added It is possible that more channels may need to be added if larger volumes of subscribers are added Capacity plus ideally can support 100 subscribers / slot If attempting to put 300 subscribers on a 2 slot voice system “busies” could result. Adding more data radios or shortening the GPS update period could also drive the need for more revert slots on the system Plan accordingly! See the MOTOTRBO System Planner for detailed loading specifications

System Planning: Future Considerations How many users will be on the system? The number of users and talk patterns should drive the amount of voice slots required High traffic patterns will require more channels in the system to ensure a good QoS Will the system add new channels, talk groups in the future? Applies to voice and data revert channels It is important to note that all subscribers will need to be reprogrammed if new channels or TGs are added in the future. See the MOTOTRBO System Planner for detailed loading specifications

Know Your System Topology! MOTOTRBO CPS has been slightly changed to accommodate Capacity Plus programming System programmers still need to follow the same logic as programming a conventional system Plan the system in advance!

Programming methodology Like a conventional system plan the following: What are / how many voice channels do I need to program? What are the Talk groups that I need to program? What TGs do I need to hear on MY radio? Will I be using a data application If using data revert, what are the channels? Do I need more than 1 zone? Do I need to access an IP Site Connect system Do I need to access a conventional system

Example: Simple System Design Plan number of Talk Groups and users in each It is also helpful to plan ID schemes and assess assumed traffic loading Evaluate data traffic assumptions Talk Group Name Talk Group ID Users / Group Activity Applications Group A 100 40 High GPS 3 min update Group B 120 60 NO Group C 130 50 Group D 140 Low This system will have 200 users and 4 talk groups It will also require data revert channels (90 radios sending 3 minute GPS updates)

Example: Simple System Design Talk Group Name Talk Group ID Users / Group Activity Applications Group A 100 40 High GPS 3 min update Group B 120 60 NO Group C 130 50 Group D 140 Low In the following example we will program 2 voice repeaters (4 voice slots) We will program 1 Data Revert Repeater (2 data slots) Note: at 3 minute intervals 1 repeater (2 slots) can accommodate 120 subscribers We will program 1 portable for all the channels referenced and 4 Talk groups, as well as a few private ids.

Guidance on the following programming The following slides will highlight changes specific to Capacity Plus programming They assume that basic programming i.e. radio ID, group ID programming etc. are understood.

Program a Voice Repeater Open a repeater sample: Right click on zone: add “Capacity Plus Voice Channel” You may delete the default channels once you add the capacity plus channel. Program frequency information etc. Note: Adding a single channel automatically creates 2 Voice Slots labeled 1& 2. (Slot Channel ID above) Rename the channel if desired

Program a Voice Repeater On the Networks tab turn on IP Site Connect. Designate the repeater a Master or Peer. Note only 1 Master is required per Capacity Plus system

Program a Voice Repeater Repeat the same process for the secondary repeater, however, note that in the slot channel ID field you need to increment the Slot channel ID to 3, which will automatically create a 4th slot

Program a Data Revert Repeater Programming a Revert Repeater is straightforward, click on zone, add “Capacity Plus Data Channel, rename as required. Program frequency information etc. Like, Voice Channels, you will need to turn on IP Site Connect in the Networks tab NOTE: Capacity plus uses the IPSC protocol even though it operates in single site only. 

Programming Summary We now have 2 Voice Repeaters programmed Slots 1&2 We now have 1 Data Revert Repeater You will need to verify that you have turned IP Site Connect on for both repeaters. Capacity plus uses the IPSC protocol

Program a Subscriber Radio: Group IDs Add Capacity Plus Group IDs

CPS Quick Start – Subscriber checklist CapPlus RX Group Lists –What Talk groups do you need to hear?

Program a Subscriber Radio: RX Group List On the RX Group List, highlight TG List 1 under Capacity Plus. Then highlight and add the TGs to this list. These are the TGs that you wish to hear on your subscriber. You may rename this list.

CPS Quick Start – Subscriber checklist Add Voice Channels in Pool – One covers both slots (only 1 entry for each repeater)

Programming the Subscriber: Channel Pool Capacity plus subscribers contain a special zone called a Channel Pool This zone allows programmers to add all the channels that may potentially be used in the system Analog Digital Capacity Plus Voice Capacity Plus Data This zone is deliberately not viewable by the end user This becomes a “holding place” for all channels that don’t need to be directly accessed by the end user Via channel knob / rocker Or via menu Reasoning: There is no reason for the user to physically access a data revert

Program a Subscriber Radio: Add Voice Channels to Channel Pool Under Channels, you will see Channel Pool, right clicking on the Pool will allow you to add any type of MOTOTRBO channel. Add Capacity Plus Voice Channel this will create a single channel, however it will encompass (2) Voice Slots

CPS Quick Start – Subscriber checklist Add Data Channels in Pool – One for each slot (2 entries for each repeater)

Program a Subscriber Radio: Add Data Channels to Channel Pool Right clicking on the Pool will allow you to add any type of MOTOTRBO channel. Add Capacity Plus Data Channel this will create a single channel, however it will encompass (1) Voice Slots. This will need to be done twice / repeater.

Program a Subscriber Radio: Add Data Channels to Channel Pool Note: Adding a Data channel only creates (1) data slot, therefore (2) must be added / repeater. You will need to assign a slot to each data channel created. All channels (voice & data) can be renamed to coincide with their function

CPS Quick Start – Subscriber checklist Build Voice Channel Lists – add Voice Channels in order

Program a Subscriber Radio: Create Voice Channel List Under Capacity Plus entry, Create a Voice Channel List, this is all the channels that will be accessible in the Capacity Plus system. Add them according to their slot order, i.e. 1&2, then 3&4….

CPS Quick Start – Subscriber checklist Build Data Revert Lists – order doesn’t matter

Program a Subscriber Radio: Create Data Revert List Follow the same process for the data channel list. Order of addition to the list does not matter.

CPS Quick Start – Subscriber checklist Add a CapPlus Personality to regular Zone Reference Voice List Reference Data List Reference RX Group List Reference TX Contact Remove any default Analog or Conventional Digital Channels that you are not planning to use.

Program a Subscriber Radio: Create A Capacity Plus Personality Under the Zone, right click and Add Capacity Plus Personality, you may delete the rest of the channels in the zone once added. These channels are defaulted there. You can also rename the personality to be more descriptive

Program a Subscriber Radio: Program the Capacity Plus Personality If using data, turn on ARS Add Voice list created in previous step 1 Add Data list created in previous step 2 Choose Contact TG Add RX list created in previous step 4 3

Listen / Talk to only one talk group It’s easy to program a Capacity Plus radio to talk and listen to a single talk group When creating RX list ONLY add the single TG that you wish to hear Add that TG as your Contact Name on the Capacity Plus Personality ONLY add TG A to Rx List TG A is the contact name on the Capacity Plus Personality

Programming Summary So…what do we have? 2 Voice repeaters Slots 1&2 Slots 3&4 1 Data Repeater Slot 1 Slot 2 4 Talk Groups

Understanding Capacity Plus Beacons The Capacity Plus repeater hosting the rest channel will send out a beacon every Beacon Interval (ms). The subscriber units listen for the beacon and if they don’t hear it in the specified interval they’ll go thru the Voice List looking for the next rest channel. If a subscriber hasn’t found a rest channel in the Rest Channel Acquisition TOT (min) then it will sound a tone indicating to the user that it has lost the system. The intervals for the repeater and subscriber should be set to the same value.

Understanding Capacity Plus RSSI Threshold FCC Type 1 compliance may not be an issue for areas outside the United States. However, the RSSI Threshold (dBm) is used in Capacity Plus systems to determine if a repeater is available to become the next rest channel or not. For example, if the RSSI Threshold (dBm) is set to -115 for repeater 1 in a 4 repeater Capacity Plus system and the rest channel is currently on repeater 2. Repeater 1 may have RF interference (analog or digital) above that threshold at -110dBm then repeater 1 channel will be considered ‘busy’ and it will take itself out of contention to become the next rest channel and the next rest channel would end up being assigned to repeater 2, 3 or 4. If you always want the repeater to be considered a candidate for the next rest channel assignment regardless of ambient RF levels you should set this value to the maximum -40dBm value.

Improving Channel Capacity by Adjusting Hang Times MOTOTRBO supports message trunking by keeping a channel reserved for the duration of hang time after a transmitting radio has de-keyed the microphone. During the hang time, only the members of the ongoing call can start a transmission. The advantage is that it provides guaranteed access to the channel for the duration of a call. The disadvantage is that the channel remains unused during the hang times. To improve channel utilization, change the call hang time in the repeater. Set to Zero (0) - system acts as if the channel is allocated for only one transmission (Transmission Trunking) Reduce call hang time from the default value - may improve overall call throughput if there are many members in a group, and they are replying instantly to the group call Increase call hang time from the default value if the group members are not replying instantly to the communication and the channel still needs to be reserved, to prevent group call participants from switching to other group calls or loosing the channel when the system may becomes busy with other calls

Ways to Improve Data Throughput Compress the UDP/IPv4 headers between radios (including control stations) applies to clear, Basic Privacy, and Enhanced Privacy transmissions in both repeater mode and direct mode transparent to server applications Radios sends compressed data messages only if the feature is enabled, but they process compressed data messages even if the feature is disabled. A legacy MOTOTRBO radio cannot receive compressed data messages. Use unconfirmed data message Note: GPS data in IP Site Connect and Capacity Plus modes is always unconfirmed and not configurable Transmit a data message with or without the preambles MOTOTRBO radio sends one (in repeater mode) or two (in talkaround mode) preambles for increasing the battery life. If there are legacy radios (i.e. release 1.4 or earlier) in the system, all the radios in the system should be configured to send battery saver preambles.

Call Priority in Capacity Plus Mode If there is more than one calls active in a Capacity Plus system, then a radio joins its most preferred call in the following conditions: The call that the radio was participating in, ends A radio powers on, or returns from a fade when all trunked channels are not busy. The preference list for a radio (in decreasing order) is: All Call the radio’s transmit talkgroup the radio’s receive talkgroup Call priority is enforced by a radio only while it is entering a call. Once the radio joins a call, it will not look for any other high-priority call in the system (except an All Call).
