General Product Description
Remote Site starts survival mode operation in the following cases.
-
When the communications (Keep Alive signal) in every 30 seconds between Main
Site and Remote Site are interrupted for the predetermined time set by CM0B Y=3
1-60>50 on normal mode operation.
-
When Remote Site cannot be connected to Main Site or is not allowed connecting
to Main Site after the system reset of the Remote Site.
Remote Site is reset automatically to change the operation from normal mode to
survival mode when it detects an interruption of the communications from/to Main
Site.
When Remote Site starts the survival mode operation, the fault information "Initialize
by CAT or MAT" is registered to the MP card of Remote Site. In addition,
"Communication error occurrence between Main Site and Remote Site" is registered
to the MP card of Main Site at 20 seconds later from the predetermined time set by
CM0B Y=31-60>50.
Remote Site on survival mode checks at every 30 seconds if the communications to
Main Site are possible. When the Remote Site regards that the communications are
possible, "Communication error restoration between Main Site and Remote Site" is
registered to the MP card of Main Site at 20 seconds later from the predetermined
time set by CM0B Y=3 1-60>51.
When Remote Site on survival mode regards that the communications to Main Site
are possible, manual changeover (system reset) is required. Automatic changeover (re-
connection to Main Site) is also selectable in system data programming. At the
automatic changeover, Remote Site system is initialized and the calls on going are
disconnected 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 IP
network fails, the Remote Site system works as a survival mode. In this case, prior to
R12.2, the station user have to dial an outside telephone number associated with the called
station number to call to the station in the Remote PIM network. In R12.2 software, if IP
network 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 number
to the outside telephone number and makes the outgoing call via ISDN.
