  • Page 9: Dmr Introduction

    Hytera adopts the DMR technology and develops the digital radio compatible with analog work mode. Hytera DMR radios can convert analog signals into digital signals, and transmits both data and voice.

  • Page 10: Analog Communication Vs Digital Communication

    Hytera DMR System Planner 1.1 Analog Communication VS Digital Communication Analog communication has poor privacy protection. The signal transmitted by an analog radio can be received by any other analog radio on the same channel. Thus interference easily occurs in analog communication. However, digital communication employs some technologies such as color code, which significantly enhance the interference resistance.

  • Page 11: Hytera Dmr Technology Introduction

    Hytera adopts the DMR technology and makes developments in compliance with the ETSI DMR Tier II standards. Hytera DMR radio collects the audio signals at the microphone, converts the audio signals to analog signals, and then converts the analog signals to digital signals. In addition, the sampling signal should be strong enough to ensure high audio quality, so certain techniques are required to compress the signal.

  • Page 12: Hytera Dmr Technology Highlights

    With Hytera DMR radios, it becomes possible to use two slots simultaneously. For example, you can receive audio and data simultaneously on both slots, or transmit audio on one slot while receive signaling to realize special functions, such as Priority Interrupt, on the other slot.

  • Page 13: Brief Introduction Of Dmr Functions

    2 Brief Introduction of DMR Functions DMR digital communications system realizes voice services (such as group call, private call, all call, etc.), data services (such as text message, GPS data, ect.) and supplement services. This chapter mainly introduces some basic functions and their parameter configurations of DMR conventional system.
  • Page 14 Direct and Repeater modes. And in Repeater mode, the slot is alternative. Note: Pseudo Trunk is one of the Hytera patents. Generally, in Repeater mode, DMR standard protocol defines radios to transmit in the fixed slot. If the slot is occupied, the radio has to wait for it instead of another free slot, wasting the frequency band resources.

  • Page 15: Voice Services

    Hytera DMR System Planner 2.2 Voice Services DMR voice services support group call, private call and all call. It means that you can make a call with a group, a person and all users in the system. 2.2.1 Group Call A group call is transmitted to a group by a user.

    Hytera DMR System Planner call making. You may add the ID or alias of the contacts into the contact list via the CPS or the radio menu. Even if you do not add the ID or alias, you can also enter the call ID of a contact for calling.
  • Page 17 Hytera DMR System Planner Figure 2.2.4-1: Phone Network System via Local PSTN Gateway Figure 2..2.4-2: Phone Network System with Multi-site PSTN Gateway The Phone feature realizes the connection between the repeater and the PSTN network by transmitting a call and DTMF signaling, so as to achieve the communications between the radio and the phone.
  • Page 18 Hytera DMR System Planner the repeater and the public switched telephone network (PSTN) respectively, achiving its communications with a specific phone. The call ends when the radio sends the de-access code or when the phone is hung up. Like the call between the radios, the call between the radio and the phone is subject to time limit.
  • Page 19 Hytera DMR System Planner code directly. The repeater will transfer the received DTMF code to the PSTN gateway to connect the phone system for communications between the radio and the phone. When a call is received from the phone, the radio needs to send the DTMF code to put through the call.

  • Page 20: Data Service

    However, you are not able to check or edit it through the radio. You can use a Hytera DMR radio to send text message to an individual user, a group or the control station, and reply or forward the message to other radios.

  • Page 21: Gps

    Hytera DMR System Planner The Tx Admit settings of private message are the same as those of private call. The same as group call, group message requires that all the members must be in the same slot on the same channel and have the consistent Tx and Rx frequency and color code.

  • Page 22: General Services

    Hytera DMR System Planner 2.4 General Services 2.4.1 Supplementary Service Hytera DMR has the same supplementary service feature mechanism with Motorola. Hence, these two brands of radios can communicate with each other. Hytera DMR radios have five supplementary services as follows:...
  • Page 23 Hytera DMR System Planner The target radio is stolen. You fail to use the radio properly. You need to have handsfree communications.

  • Page 27 Meanwhile, the voice super frame will be embedded with some synchronous encryption information to prolong the system delay access time. Hytera encryption defines its own way in embedding the encryption parameter into the voice super frame, which is different from the DMRA encryption.

  • Page 28: Telemetry

    The Telemetry feature can help users to realize the remote monitor on the devices any time. Currently, Hytera Telemetry feature is only available for conventional portable and mobile radios in digital mode, except repeaters. The telemetry feature allows you to monitor and control the status of GPIO pins for a mobile radio attached to the external device, which in turn can monitor this device remotely by another mobile radio.
  • Page 29 Hytera DMR System Planner Figure 2.4.4-1: Telemetry Principle The connection between the radio and the device is fulfilled by the third party who will determine the connection form. The portable radio supports one telemetry VIO (GPIO Pin1). The mobile radio supports 6 telemetry VIOs.
  • Page 30 Hytera DMR System Planner Figure 2.4.4-2: GPIO Interface of Portable Radio GPIO Interface of Mobile Radio The mobile radio supports 6 telemetry VIOs. GPIO Pin3, Pin12, Pin 16, Pin20, Pin22 and Pin23 can be set to the telemetry VIO. See the following figure:...
  • Page 31 Hytera DMR System Planner Voltage Range of GPIO Pin For mobile radio: High TTL: 3.6–5V; Low TTL: 0–2.4V GPIO Pin input: 0–1.2V (low); 2.0–5V (high). GPIO Pin output: 0–0.8V (low); 2.4–5V (high). For portable radio: GPIO Pin input: 0–0.3V (low); 0.7–3.3V (high).

  • Page 32: Vox

    Hytera DMR System Planner 2.4.5 VOX The VOX (Voice-operated Transmit) feature indicates that you can trigger the voice transmission by voice directly rather than PTT. This brings more convenience to you in radio use. After this feature is enabled, when the microphone detects that your voice reaches the required volume to trigger the transmission, your voice will be transmitted automatically.
  • Page 33 Hytera DMR System Planner Note that the voice transmission via VOX is the same as holding down PTT in that the radio will also give a tone for available communication. During transmission, if no voice is detected, the radio will start VOX Hold Time counting. If the time is over without any voice detected, the transmission will terminate and the radio will enter the Call Hang Time.

  • Page 34: Emergency Alarm

    Hytera DMR system provides four types of emergency alarms: Siren Only: The radio emits siren locally. Regular: The radio gives visible and audible indications during emergency state.

  • Page 35: Alarm

    Hytera DMR System Planner Alarm mode is used to inform the other radios in the system that you need help. Those radios will check the ID of the transmitting radio and take actions. This emergency mode can inform the other users that you are in danger, but it cannot tell your actual situation.

  • Page 36: Emergency Call

    Hytera DMR System Planner 2.5.2 Emergency Call This mode indicates that the radio will transmit the emergency call on the emergency channel, and then directly enter the emergency status instead of transmitting the emergency code and waiting for the ACK. You can transmit the emergency call by holding down PTT.

  • Page 37: Lone Worker

    Hytera DMR System Planner 2.5.4 Lone Worker Lone Worker emergency is used to ensure your safety. You can set a time period for your radio. If no keypad operation is made on the radio within this period, the radio will trigger the emergency alarm automatically. This feature is designed for people (such as police, firefighters, miners, etc.) in dangerous workplaces.

  • Page 38: Man Down

    Hytera DMR System Planner Lone Worker Process: Figure 2.5.4-1: Lone Worker Process 2.5.5 Man Down Man Down emergency is also used to protect you.

  • Page 39 Hytera DMR System Planner As the Man Down feature is more sensitive and timely to send emergency alarms, it should be used in appropriate occasions and defined reasonably. To use this feature, you need to configure its parameters via the CPS. The Trig Entry Delay Time is used to set the time period for activating the emergency alarm.

  • Page 40: Scan

    Hang Time is up. Then the radio will continue detecting the channels repeatedly until it quits the Scan mode. Hytera DMR scan supports both digital channels and analog channels.
  • Page 41 To meet your needs, Hytera DMR provides the Scan Tx Mode configuration in the CPS, so you can designate a channel for the transmission during the scan.

  • Page 42: Scan List

    Hytera DMR System Planner is: 0.5s to 7.5s. The shorter the set time, the faster the radio will return to the first channel for scanning, and the more the scanning of the priority channel. Thus the detection to the first channel activities will not be missed.

  • Page 43: Scan Stay Condition

    Hytera DMR System Planner 2.6.2 Scan Stay Condition The radio detects the signal and determines whether to stay on the channel during scanning. The CTCSS/CDCSS can be set as the scan stay condition for the analog channel. Generally, the voice transmission on the analog channel is accompanied by the CTCSS/CDCSS.

  • Page 44: Channel Scan Order

    Hytera DMR System Planner 2.6.3 Channel Scan Order The scan list can be edited via the radio menu or the CPS, to change the channel order in the channel list and to set the priority scan channel. Pay attention to the following information while editing the scan list: Make sure the Selected channel refers to a channel different from the other channels in the scan list.
  • Page 45 Hytera DMR System Planner Scenario 2: The scan list contains both the digital channels and analog channels. For example, CH1, CH3, CH5 and CH7 are digital channels, and CH2, CH4 and CH6 are analog channels. If the Selected channel is an analog channel and refers to a channel different from the other channels in the scan list, the channels in the scan list will be in this order: Selected, CH2, CH4, CH6, CH1, CH3, CH5 and CH7.
  • Page 46 Hytera DMR System Planner 2.6.3.3 Two Priority Scan Channels Supposing CH1 and CH2 are set as the priority scan channels, the channels in the scan list will be in this order (Selected, CH1, CH2, CH3, CH4, CH5, CH6 and CH7), no matter whether they are analog channels or digital channels.

  • Page 47: Roaming

    The Roaming feature, mainly used in the IP Multi-site Connect system, can bring users seamless communication within the area covered by multiple repeaters. Hytera DMR digital terminals are capable of auto roaming from one site to another within the IP Multi-site Connect system.

  • Page 48: Roaming Methods

    Hytera DMR System Planner When the mobile terminal is roaming, the corresponding status icon and the master site (channel) alias will be displayed on the LCD. Also you can determine whether the terminal is searching or staying on the site with the help of the LED.
  • Page 49 Hytera DMR System Planner Auto site roam is not triggered by one of the following events: The mobile terminal is transmitting The mobile terminal is receiving a call or data service The mobile terminal is in Emergency mode The mobile terminal is in good coverage...
  • Page 50 Hytera DMR System Planner as short as possible. This ensures that the auto site roam finds a new site rapidly and disallows the user to initiate the active site roam. Note: roaming will not occur in the emergency mode if the active site roam is disabled.

  • Page 51: Configuring The Rssi Threshold

    Hytera DMR System Planner 2.7.2 Configuring the RSSI Threshold The RSSI Threshold is a configurable parameter via the CPS. If the signal strength of the current master site is above the specified RSSI threshold, the terminal will stay on the site and will not roam. Once the signal strength falls below the threshold, the auto site roaming will occur to search for a site with higher signal strength.
  • Page 52 Hytera DMR System Planner account before setting the RSSI threshold. Generally, the following four site configurations are available for your reference. 2.7.2.1 Overlapping coverage This scheme is designed for a large city or an area where a large population is present.
  • Page 53 Hytera DMR System Planner TX=F1 TX=F1 RX=F2 RX=F2 CC=1 CC=2 TX=F3 TX=F1 RX=F4 RX=F2 CC=3 CC=4 Figure 2.7.2.2-1：Non-overlapping Coverage 2.7.2.3 Linear coverage This scheme is designed for communication services along the road, railway, river or coastline. It involves multiple sites and overlapping coverage is present on a small scale.
  • Page 54 Hytera DMR System Planner 2.7.2.4 Multilayer coverage This scheme is designed for a high-rise building or a deep well. It involves multiple sites standing close from each other and overlapping coverage is present on a large scale. Since the coverage of each site is limited due to unfavorable geology conditions, frequency reuse is seldom available, and quick signal attenuation occurs frequently.

  • Page 55: Setting Beacon Duration And Beacon Interval

    Hytera DMR System Planner Please note that the above RSSI thresholds assume the outbound and inbound RF coverage of the system is balanced. In other words, when the terminal is within good outbound coverage of the repeater, the terminal’s inbound transmission can reach the repeater.
  • Page 56 Hytera DMR System Planner increased. If the beacon duration is very short, it may be difficult for the terminal to detect it. This is especially true if there are more sites. If the terminal detects a specific site at longer intervals, it is more likely for the terminal to miss the beacon. Typically, a user is within the coverage of no more than four sites at any given time.
  • Page 57 Hytera DMR System Planner No. of Sites Beacon Duration[s] Beacon Interval[s] 0.72 1.92 3.12 4.32 5.52 6.72 7.92 9.12 10.32 11.52 12.72 13.92 15.12 16.32 If shared use is not a problem in the customer’s region, the beacon transmission ratio becomes less important. And it may be desirable to increase the beacon duration and decrease the beacon interval.

  • Page 58: Performance While Roaming

    Hytera DMR System Planner 2.7.4 Performance while Roaming Please note that roaming may cause performance degradations. Therefore, the RSSI threshold and the terminal’s Site Lock must be set appropriately when not in mobile status. The degradations are similar to what the terminal will experience during scanning.

  • Page 59: Hytera Patented Features

    Pseudo Trunk is a function innovated by Hytera. This function is used to assign two time slots dynamically in direct mode. When one slot is busy, the subscriber will have communication on the other slot automatically.
  • Page 60 Hytera DMR System Planner Application in Direct Mode The bi-slotted operation is available in Direct mode once you have activated it on your desired channel. In Direct mode, Pseudo Trunk is usually applied in three instances: There are only the subscribers which are using Pseudo Trunk function.
  • Page 61 Hytera DMR System Planner There are subscribers using Pseudo Trunk and a single time slot respectively. Figure 2.8.1-2：Pseudo Trunk Application in Direct mode 2 Pseudo Trunk supports the communication with non-Pseudo Trunk subscriber, which means that a subscriber with Pseudo Trunk can have normal communication with a subscriber with a conventional single time slot on the same channel.
  • Page 62 Hytera DMR System Planner The analog carrier occurs in the channel. The occurrence of the analog carrier on the digital channel will be taken as that both slots are occupied, and the subscriber will determine whether to transmit according to TX Admit settings.
  • Page 63 Hytera DMR System Planner status of the slots. If its Tx slot is designated, A will detect the status of the Tx slot first, and then determine whether to transmit according to TX Admit settings. If the channel is free, and Subscriber A doesn’t have a designated Tx slot, Slot 1 will be the default Tx slot for A to establish the communication with B.
  • Page 64 Hytera DMR System Planner Admit settings. Comparatively, slot 2 will have small probability to be occupied, as it will only be selected by the subscriber using Pseudo Trunk when Slot 1 is busy, so we suggest you to designate Slot 2 for part of the pseudo-trunk subscribers.
  • Page 65 Hytera DMR System Planner case of activities on the channel, the first used slot will be taken as Slot 1. When the subscriber receives the call in Slot 1, it will call back in Slot 1, too. If Slot 1 is occupied, the subscriber will determine whether to transmit according to TX Admit settings.

  • Page 66: Priority Interrupt

    Hytera DMR System Planner When TX Admit is set to “Allow”, the subscriber will transmit on Slot 1. When TX Admit is set to “Color Code Free” or “Channel Free”, and Slot 1 is busy, the transmission will be refused.
