In addition,“Communication error occurrence between Main Site and Remote Site” is registeredto the MP card of Main Site at 20 seconds later from the predetermined time set byCM0B Y=31-60>50.Remote Site on survival mode checks at every 30 seconds if the communications toMain Site are possible. When the Remote Site regards that the communications arepossible, “Communication error restoration between Main Site and Remote Site” isregistered to the MP card of Main Site at 20 seconds later from the predeterminedtime set by CM0B Y=3 1-60>51.When Remote Site on survival mode regards that the communications to Main Siteare possible, manual changeover (system reset) is required. Automatic changeover (re-connection to Main Site) is also selectable in system data programming. At theautomatic changeover, Remote Site system is initialized and the calls on going aredisconnected due to the reset of terminals.Backup Call Routing to ISDN in Remote PIM Survival Mode (R12.2)Calls within a Remote PIM over IP network are made by dialing a station number. If IPnetwork fails, the Remote Site system works as a survival mode. In this case, prior toR12.2, the station user have to dial an outside telephone number associated with the calledstation number to call to the station in the Remote PIM network. In R12.2 software, if IPnetwork fails, calls to Main/Remote Sites can be automatically routed via ISDN network.When the calling station dials the called station number, the system translates that numberto the outside telephone number and makes the outgoing call via ISDN.
