MCC 710017500 Trunked Resources 2. TEST <br />Step 1. Initiate a Channel Marker tone on <br />TALKGROUP 1 from CONSOLE -1. <br />3.1,8 Channel Marker Step 2. Verify RADI0-1 and RADIO -2 can <br />monitor the Channel Marker tone on <br />TALKGROUP 1. <br />1, DESCRIPTION <br />A Channel Marker is a distinct, short duration, <br />audible tone over radio and Console speakers. <br />The tone is initiated and cancelled by a console <br />operator. <br />The tone can be initiated only for the talkgroups or <br />conventional channels. On initiation, it is <br />generated periodically when there is no voice <br />activity. The tone can be used for various <br />purposes. The primary purpose of the tone is to <br />inform radio users that the conventional channel <br />or the trunked talkgroup Is currently involved in a <br />high priority situation and they should stay off the <br />channel unless they are Involved in the high <br />priority situation. The tone also informs the users <br />that a console operator is actively monitoring the <br />talkgroup. <br />Note that the Channel Marker tone will only start <br />when there is no voice activity for the selected <br />Talkgroup or conventional channel. The channel <br />Marker tone is sent in a current transmission <br />mode of the Console user. <br />SETUP <br />RADIO -1 - TALKGROUP 1 <br />RADI0-2 - TALKGROUP 1 <br />CONSOLE- 1- TALKGROUP 1 <br />CONSOLE- 2- TALKGROUP 1 <br />VERSION #1,010 <br />City of Santa Ana <br />MCC7500 P25 Dispatch Migration and Subscribers <br />0 Motorola Solutions Confidential Restricted <br />Step 3, Verify CONSOLE -1 and CONSOLE -2 <br />also monitor the Channel Marker tone <br />on TALKGROUP 1. <br />Step 4.
