Programming OverviewProgramming logicProgramming a system

Contents

A trunking radio system differs from a conventional radio system in the way it shares channels between radios

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

What is Trunking?

How does it work?

Process is repeated over and over ensuring optimal performance!

1. All new calls always start on the Rest Slot

2. 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

1. 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? - Repeater

1. All possible Voice Slots are programmed into the subscribers

Radio must know of the channel to utilise it

1. Upon power up:

Radio performs a passive search for Rest Slot

Listens for an active rest channel

1. 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

How does it work? - Subscriber

1. 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 arent required

1. 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

Rest Slot Benefits

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 its 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. Theres 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.

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

Data on 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

Revert & Voice Slots

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

Capacity Plus Data Revert

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.

Do Data Revert Slots Trunk?

Greatly increases channel efficiency Voice calls do not disrupt data More data can be offloaded on system Example: Faster GPS update periods

Capacity Plus Data Revert: Value Proposition

Subscriber cycles through its list of data revert slots to send its dataSubscriber evaluates up to 4 data revert channels

Tries to find an idle channel and TX the data

Understanding the subscriber revert process

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

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

Data Reverts Channel: How it works?

It is not required to create a data revert system Radios can be programmed to send data on voice slots

This can reduce data reliability and QoS Especially in very large fleets

System Planing &System Planing &ProgrammingProgramming

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 Frequencies

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!

System Planning: Channel Loading Considerations

See the MOTOTRBO System Planner for detailed loading specifications

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.

System Planning: Future Considerations

See the MOTOTRBO System Planner for detailed loading specifications

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!

Know Your System Topology!

Like a conventional system plan the following:

1. What are / how many voice channels do I need to program?

2. What are the Talk groups that I need to program?

3. What TGs do I need to hear on MY radio?

4. Will I be using a data application

5. If using data revert, what are the channels?

6. Do I need more than 1 zone?

1. Do I need to access an IP Site Connect system

2. Do I need to access a conventional system

Programming methodology

1. Plan number of Talk Groups and users in each

2. It is also helpful to plan ID schemes and assess assumed traffic loading

3. 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 High NO

Group C 130 50 High NO

Group D 140 50 Low GPS 3 min update

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

Example: Simple System Design

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.

Talk Group Name Talk Group ID Users / Group Activity Applications

Group A 100 40 High GPS 3 min update

Group B 120 60 High NO

Group C 130 50 High NO

Group D 140 50 Low GPS 3 min update

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.

Guidance on the following programming

Open a repeater sample:Right click on zone: add Capacity Plus Voice ChannelYou may delete the default channels once you add the capacity plus channel.Program frequency information etc.Note: Adding a single channel automatically creates 2 VoiceSlots 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


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


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.

Program a Data Revert Repeater

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

Program a Subscriber Radio: RX Group List

Add Voice Channels in Pool One covers both slots (only 1 entry for each repeater)


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 dont 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

Programming the Subscriber: 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

Program a Subscriber Radio: Add Voice Channels to Channel Pool

Add Data Channels in Pool One for each slot (2 entries for each repeater)


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

Program a Subscriber Radio: Add Data Channels to Channel Pool

Build Voice Channel Lists add Voice Channels in order

Programming Summary

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 dont hear it in the specified interval theyll go thru the Voice List looking for the next rest channel. If a subscriber hasnt 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 Beacons

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.

Understanding Capacity Plus RSSI Threshold

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

Improving Channel Capacity by Adjusting Hang Times

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.

Ways to Improve Data Throughput

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 radios transmit talkgroup

the radios 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).
