What is Trunking? A trunking radio system differs from a conventional radio system in the way it shares channels between radios Trunking Conventional • 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
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

A B C D F G 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 Slot 1 Slot 2 Slot 3 Slot 4 IP Switch
C TG C B A A C C B A B How does it work? Process is repeated over and over ensuring optimal performance! Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 Slot 6 IP Switch Slot 7 Slot 8
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.
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
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
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 Fault Tolerance Conditions Voice Repeater Fails IP Switch fails 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 futureusers 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 • This system will have 200 users and 4 talk groups • It will also require data revert channels (90 radios sending 3 minute GPS updates)
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. Example: Simple System Design
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 • Slots 3&4 • We now have 1 Data Revert Repeater • Slots 1&2 • You will need to verify that you have turned IP Site Connect on for both repeaters. • Capacity plus uses the IPSC protocol
