DMR CHANNEL OVERVIEW

All communication between any two DMR digital radios will include the following four codes:

Color Code A Color Code from 0 to 15. Color Codes work much like QC/DQC codes in Analog mode, and are often used in

conjunction with an Individual ID or Group ID code to screen calls when receiving, and to uniquely identify the

radio when transmitting. An RX Color Code of 0 allows all Color Codes to be received.

SUID The Subscriber Unit ID Code (from 1 to 16,776,415) is the unique Individual ID of the radio. When an incoming

message type is Individual and matches the radio SUID, the message will be received.

Group ID A Group ID code (from 1 to 16,776,415) determines which call-groups the receiver belongs to. The radio can be

programmed to receive up to 48 different Group ID codes on any DMR channel. Group ID codes are stored in

the radio as DMR Contacts where an 8-character name can be assigned. The DMR Contact name will appear

on the display when the Group ID is received.

Call Type Call types are Group, Individual or All Call. With a Group call type the radio will receive Group ID codes that

match those programmed into the selected radio channel. With an Individual call type the radio will only receive

calls that match the radio SUID. With All Call type the radio receives any Group call, regardless of radio

programming.

RECEIVE – DMR CHANNELS

The radio can only receive broadcasts while the Push-To-Talk button is not being pressed. Whether or not you hear these

broadcasts depends upon the squelch settings.

There are four squelch type that can be used on a DMR channel

Off The radio will receive all on-frequency DMR voice calls. Color Code, Individual or Group ID codes are not

required. Squelch Type OFF is similar to carrier squelch operation in an analog radio.

Color Code The radio will receive all calls with the programmed Color Code. Squelch Type Color Code is similar to using

QC/DQC codes in an analog radio.

ID The radio will only receive calls with its programmed SUID code, a programmed Group Call code, or the All Call

code. Squelch Type ID is similar to using 2-Tone, DTMF or Selcall to selectively call the radio in an analog

radio.

Color Code & ID The radio will only receive calls with the programmed Color Code AND with its programmed SUID code, a

programmed Group Call code, or the All Call code. Squelch Type Color Code + ID is similar to using QC/DQC

and 2-Tone, DTMF or Selcall to selectively call the radio in an analog radio.

NOTE: The term “valid DMR call” is used to indicate that the incoming DMR call satisfies the Squelch Type programming.

When the radio is in standby mode with no incoming signal

 The display will indicate the Channel Name.

When receiving a valid DMR call with an ID code contained in the DMR Contacts list

 The display will indicate the DMR Contact Name and “RX” will appear on the 2

line.

 The incoming signal will be heard on the radio speaker.

 When the incoming signal has ended the display will continue to show the DMR Contact for the

programmed DMR Hold Time to allow a response to the call.

When receiving a valid DMR call with an ID code not contained in the DMR Contacts list

 The display will indicate the DMR Group or Individual ID code and “RX” will appear on the 2

line.

 The incoming signal will be heard on the radio speaker.

 When the incoming signal has ended the display will continue to show the DMR Group or Individual ID

code for the programmed DMR Hold Time to allow a response to the call.

When a received signal is present that does not match channel programming

 The display will indicate the Channel Name and “Busy” will appear on the 2

line.

 The incoming signal will not be heard on the radio speaker.
