Call Sequencing
If another request arises during communication, the calls are queued. Calls have
different priorities – fire call have the highest one. Therefore, the alarm call suspends
any lower-priority call (the checking call, e.g.). Calls with identical priorities are
queued and processed one after another. Having done that, LN recovers the
suspended activity if possible.
