Port Interface Modules (PIMs)

NEAX 2000 IPS consists of a number of Port Interface Modules (PIMs) depending on
the system configuration. There are two types of PIMs:
• Physical PIM
• Virtual PIM
The Physical PIM is a hardware PIM and is used to accommodate an MP, FPs, IP
PADs, Legacy LT and AP cards, and power supply units. One Physical PIM provides
up to 64 LT ports.
The Virtual PIM is a software PIM and is used to assign Dterm IP telephones by
system programming (The Physical PIM can be used to assign Dterm IP telephones,
but is not essential.). One Virtual PIM provides up to 64 Dterm IP telephones. The
system consists of up to eight PIMs, by the combination of Physical PIMs and Virtual
PIMs, thus providing a total of 512 ports for Dterm IP telephones and Legacy LT
cards. Total number of ports for Dterm IP telephones and Legacy LT cards must be
less than 512, so the number of Physical PIMs decreases when that of Virtual PIMs (=
number of Dterm IP telephones) increases.
When 256 Legacy LT ports are required (= four Physical PIMs), the
Example:
maximum number of Dterm IP telephones is 256.
Figure 2-1 shows examples of 512-port configuration by the combination of Legacy
LT ports and Dterm IP telephones.
