SYSTEM CONFIGURATION
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 D
term
IP telephones, D
term
SP30 or IP-BS by system
programming. One Virtual PIM provides up to 64 D
term
IP telephones. The system consists of up to 8 PIMs,
by the combination of Physical PIMs and Virtual PIMs, thus providing 956 ports for D
term
IP telephones and
512 ports for legacy LT cards. The total number of ports for D
term
IP telephones and legacy LT cards must be
1020 or fewer, so that the number of Physical PIMs decreases when that of Virtual PIMs (= number of D
term
IP
telephones) increases. For example, when 256 legacy LT ports are required (= four Physical PIMs), the
maximum number of D
term
IPs is 256.
The figure below shows examples by combination of legacy LT ports and D
term
IP telephones.
