General Product Description
Service Conditions
 Host site can be SOPHO 2000 IPS, SOPHO IPS DM
 Software and Key FD for the whole system must be loaded at the Host Site. No
software or key's can be loaded into the Remote Site.
 All system data changes for the whole system must be performed in the Host Site. No
system data changes can be done in the Remote Site.
 The CPU card at Remote Site has the same system data as the CPU at Main Site; the
Host Site automatically downloads its system data to the Remote Site at the time of
setup. In normal operation, Host Site automatically copies the system data to Remote
Site through the network once a day.
 Remote Site automatically operates by itself (survival mode) when Keep Alive signal
(sent every 30 sec) between the Host Site and Remote Sits is interrupted. When Keep
Alive is interrupted the Remote Site is reset to change the operation from normal
mode to survival mode.
 Remote Site in survival mode checks at 30 seconds intervals if the communications to
Main Site are possible. When Keep Alive is detected, the Remote Site automatically is
reset to change the operation from survival mode to normal mode.
 When unstable conditions occur in the network, the Remote Site can be manually set
to survivable mode (override automatic) until stability in the network is established.
This prevents the Remote Site from resetting normal mode to survivable mode etc.
 Set the unique location number to each location group for proper setting of the IPPAD
channel selection and CODEC for voice compression.
 The system clock at Remote Site synchronizes with the system clock at Main Site. If
the communications to Main Site are interrupted, Remote Site does not synchronize
and operates at the hardware clock on the MP card of Remote Site.

Music and Internal Zone Paging should not be used at Remote Site considering the
