Capacity Max status: a quick way for radio users to send messages.

Status messaging is a Capacity Max (only) feature that allows the transmission of a 7-bit packet on the control channel. The number sent in this packet is mapped to a preconfigured text string in all radios. This means that if radio A sends status 01, it has the same meaning on all radios.

7 bits allows for 128 possible statuses but status 100 to 128 are reserved.

It is possible for a user to send a status to another radio; a talkgroup or a dispatch application (as long as that application supports status).

Status messages are more efficient than text messages in that they are sent over the control channel using a single burst. Text messages however, require a traffic (payload) channel to be allocated and require multiple bursts to complete the call. 

What I find helpful is to assign status messages to a One Touch Call button. This allows the radio user to send the message by only pressing one button.

Here is what needs to be set up in the radio to support this:

Create a status list in (one of) the radio configuration(s). If you have more than one configuration, you can copy this set over to the other configurations.

If you intend using one touch buttons to send statuses, you need to decide which buttons will be used for this. remember that each button can be assigned to two functions.

If will use one touch buttons for sending statuses, you need to assign an action to that one touch function. Note that the other status columns refer to MDC and Select-5 status.

In the Subscriber Access Control table in the CMSS, you need to ensure that Status Call is ticked for the radios which need to send/receive status messages.

If you won't be using one touch keys, or you have other statuses not assigned to a one touch button,you will need to give access to this feature in the radio menu, if it is a display model.

Non display radio will support the sending of status messages but not the reception thereof due to no display.

Radios and systems need to be on release R2.7 or later, to support this feature. The method for sending and receiving status messages in Capacity Max is defined in ETSI TS 102 361-4 (v1.10.1) §6.6.6.
