CHAPTER 2 SYSTEM CONFIGURATION

Module Configuration

The NEAX 2000 IPS consists of Port Interface Modules (PIM) depending on the system configuration, and there are two types of PIMs; “Physical” PIM and “Virtual” PIM.

The Physical PIM is a “hardware” PIM and is used to accommodate an MP, FPs, IP PADs, legacy LT an AP cards, and power supply units. One Physical PIM provides up to 64 ports.

The Virtual PIM is a “software” PIM and is used to assign DtermIP telephones, Dterm SP30 or IP-BS by system programming. One Virtual PIM provides up to 64 DtermIP telephones. The system consists of up to 8 PIMs, by the combination of Physical PIMs and Virtual PIMs, thus providing 448 ports for Dterm IP telephones and 512 ports for legacy LT cards. The total number of ports for DtermIP telephones and legacy LT cards must be 512 or fewer, so that the number of Physical PIMs decreases when that of Virtual PIMs (= number of DtermIP telephones) increases. For example, when 256 legacy LT ports are required (= four Physical PIMs), the maximum number of Dterm IPs is 256.

The figure below shows examples of 512-port configuration by combination of legacy LT ports and Dterm IP telephones.
