INTRODUCTION
Remote PIM over IP
NEAX 2000 IPS can install a PIM at remote site through IP network. At the main site, the NEAX 2000 IPS is
installed and the Remote PIM is installed at remote site. The main site controls call processing and service
feature access for station users located both main and remote sites. When the Remote PIM cannot be connected
with the main site due to the IP network and/or main PBX failure, the Remote PIM initializes the system and
re-starts operation by its own Main Processor (survival mode). In the survival mode, almost all service features
are provided to the station users accommodated in Remote PIM. When IP network/main PBX is recovered, the
Remote PIM can be restored to normal mode by manual operation or automatically (Selectable by system data
setting).
