NEC 2000 IPS manual Advantages of Remote PIM

Chapter 1 Introduction

Advantages of Remote PIM

The system regards the terminals accommodated in both Main Site and Remote Site as the extensions in the same office. Therefore, the service transparency is superior to CCIS.

Remote PIM over IP has no limitation of distance between Main and Remote.

Remote Site has a switching function at local. This provides the effective configuration of C.O. line. In addition, the Remote Site can accommodate AP cards. This is an advantage to accommodate ISDN lines especially.

The Remote Site survives by itself even if the link between Main and Remote is disconnected. Therefore, the impact to users at the Remote Site will be smaller if the link between Main and Remote is disconnected.

This feature can reduce the bandwidth used on the WAN that is connected to CO lines at Remote Site, rather than DtermIP at remote location or the Media Converter (MC) accommodation.

Characteristics of the UNIVERGE NEAX IPS DM/IPS DML/IPS DMR

PN-CP31C for IPS DML and PN-CP31A/C for IPS DMR

Power Failure Transfer (PFT)

Power Failure Transfer (PFT) for the IPS DM is provided with PZ-4PFTA card. The PZ-8PFTB is not available for the IPS DM.

Installation Methods

The UNIVERGE NEAX IPS DM/IPS DML/IPS DMR can be installed on a desktop or into the 19-inch rack. Wall Mount Installation is not available.

Remote PIM over IP with Survivability

The UNIVERGE NEAX 2000 IPS can have a PIM installed at a remote site through an IP network. At the main site, the UNIVERGE NEAX IPS/IPS DM is installed and UNIVERGE NEAX 2000 IPS/IPS DM/IPS DMR or IPS Retro is installed at the remote site. The main site controls call processing and service feature access for station users located at both the main and remote sites. When the Remote PIM cannot be connected with 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 the IP network/main PBX recovers, the Remote PIM can be restored to normal mode with a system initialization by manual operation or automatically (Selectable by system data setting).
