• Due to its restrictive range of values, there are events when it is not entirely clear from the context, which

event has led to the output of indicator "call". Rather than as an information in itself, indicator "call" should
therefore be used as a trigger to look up the new call status in the list of current calls with AT commands

lished, or when a call enters states "terminating" or "dropped" (see chapter 

).

In these cases, the relevant information about the cause of the display is available only from AT command

. 

• The indicator "sounder" signals every event a tone is generated in the ME. For instance, if a waiting call pro-

duces a tone, this will be indicated. 

• If the ME is switched on all indicators are in registered state.
