48 Association of Master IP-CS and
Submaster IP-CS
[Series 3600]
NOTE 1:
When the IP-CS that registered as a submaster IP-CS operates as a master IP-CS because the
master IP-CS has trouble or the submaster IP-CS starts up without a master IP-CS starting, there
is no submaster IP-CS in a wireless block area. In this case, if the power failure of the IP-CS that
operates as a master IP-CS occurs, there is no IP-CS that becomes a destination of wireless syn-
chronization. And when there are multiple master IP-CSs in a wireless block area, the available
voice channels will be reduced or an electric wave meddling will occur.
To avoid these, establish one master IP-CS and one submaster IP-CS in a wireless block area by
this data setting.
The following operation is available by this data setting.
<For master IP-CS>
When the master IP-CS starts up, the IP-CS that is associated as the submaster IP-CS by this com-
mand operates as a master IP-CS, the master IP-CS operates as a submaster IP-CS. Since there
is always one master IP-CS and one submaster IP-CS in a wireless block area, the submaster
function of IP-CS (a submaster IP-CS operates as a master IP-CS when the master IP-CS is
stopped) is available, especially for the master IP-CS changing when it breaks down.
<For submaster IP-CS>
Since the master IP-CS that becomes a destination of wireless synchronization should start up
when a submaster IP-CS starts up, the submaster IP-CS does not start up until the master IP-CS
starts up (maximum 3 minutes).
The master IP-CS and the submaster IP-CS associated by this command can operate as each one,
especially for when the stating up from the master IP-CS is not possible on purpose because of
the recovery from the network trouble or power failure etc.
NOTE 2:
The association by this command is set as follows.
1. Assign the submaster IP-CS to the master IP-CS
2. Assign the master IP-CS to the submaster IP-CS
