Server Switching in the Old TwinStar
• Both servers were started as Slave/Slave
• Server assigned master after all Astribanks
register (DAHDI limitation)
• When last Astribank has left the Active server
then it will be automatically deactivated
• At least one Astribank had to be present in the
system

Server Switching in TwinStar Plus
• Switching does not depend on Astribanks
• “Heartbeat” monitoring of the other server's
health
• Once master server failure is detected the
resource manager of the “slave” server will
activate it as master
• Astribanks do not limit slave from becoming
master and vice versa
• When Astribanks are not fully switched there is
no effect on the rest of the system
