Implementation<br />
The following describes the implementation of the Mobicall Solution at <strong>IBM</strong> in<br />
Switzerland. The challenges were the integration of the interfaces using a relay<br />
server as well as the telephony network topology using Cisco Call Manager (CCM)<br />
as well as Siemens HiPath PABX. There are a total of 60 channels available, 30<br />
channels to the CCM over H323 and 30 channels to Siemens HiPath over a PRI<br />
connection.<br />
Redundancy<br />
The entire Mobicall solution is fully redundant where the master and the slave can<br />
execute any task configured. Both servers are automatically synchronized in given<br />
intervals or if the configuration has been changes on either of the servers.<br />
The servers are supervising each other and the telephony network in the main office<br />
of <strong>IBM</strong> (headquarters in Zurich) by frequently calling a predefined number on the<br />
other system. If either the call is not made or no response is received an alarm is<br />
launched notifying the responsible group.<br />
Interfaces<br />
The following systems are sending alarm information to Mobicall which then are<br />
processed and the defined action is triggered.<br />
BMA (Fire Detection)<br />
The Fire Detection system is connected trough RS232. Since the system only<br />
provides one output, it is routed through a com-port splitter box which provides 2<br />
outputs with the exact same information shared by the master and the slave.<br />
The com-port splitter outputs are connected to N-Port devices converting the serial<br />
link to TCP/IP which are connected to both servers using a separate network card.<br />
The protocol used by this interface: ESPA 4.4.4<br />
