15. OEC/ICTAP Office of Emergency Communications / Interoperable Communications Technical Assistance Program Icon Live Status Information There is a variety of live, current status information available  COR and PTT indicators appear in the lower left and right corners of the channel as audio moves through an established net  COR icon means the channel is providing audio to the net (source/message originator/sender/transmitter)  PTT icon means the channel is sending audio out to its connected device (transmission recipient/receiver) Note the COR and PTT status information can be somewhat delayed, but still useful in identifying that a net has active audio on it 15

16. OEC/ICTAP Office of Emergency Communications / Interoperable Communications Technical Assistance Program Icon Live Status Information Multiple indicator icons are available; each describes a different channel state:  No icon – The channel is idle, with no errors. On a Radio or Handset channel, this is the standard state. On other channels (PSTN, SIP, and RoIP), this means the channel is not in any active calls and is available for use.  Yellow with Dot – The channel is in progress of doing something. Typically, it is in this state very briefly while it is making or answering a call.  Yellow Waves – The channel is ringing because an outside party has called into the system. This channel may be answered using the ‘Answer’ button. This only applies to PSTN and SIP channels. 16

17. OEC/ICTAP Office of Emergency Communications / Interoperable Communications Technical Assistance Program Icon Live Status Information  Solid Green – The channel is in an active call. This only applies to PSTN, SIP, and RoIP channels.  Red With Exclamation – There is an error with this channel, or it was unable to make a requested connection (e.g., there was no dial tone on a PSTN line). Depending on the cause of the situation, you may be able to clear this status by clicking on the ‘Hang Up’ button, then clicking on the channel.  Red With Dash – This channel is offline. Something is wrong with this channel. Typically, this is only seen when an expansion system loses connectivity (and thus the channels are unreachable). 17

18. OEC/ICTAP Office of Emergency Communications / Interoperable Communications Technical Assistance Program Icon Live Status Information Current Channel Status 18 To obtain additional current status information about a channel, simply hover the mouse over the channel icon After a short delay, a status information box will appear Note: The grey circle with the ‘+’ sign indicates multiple channels are monitoring this channel.
