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 with system initialization by manual operation or automatically (Selectable by system data setting).
