Ringing sequence flowchart
This section describes the sequence of events that occur in the ringing
processes of the LCM during normal operation (non-ESA). In the "Ringing
sequence diagram" figure, the following attributes of the call are assumed:
• call is terminating on a LCM
• call is entering the ringing phase
• terminating line is 1FSR
• terminating line is idle
• immediate ringing is disabled
As the call enters the ringing state, the sequence of events shown in the
following figure occur.
