U NIVERGE NEAX 2000 IPS System Configuration
The U NIVERGE NEAX 2000 IPS consists of single or multiple Port Interface Modules (PIM)
depending on the system configuration, and there are two types of PIM’s; “Physical” PIM and
“Virtual” PIM. The Physical PIM is “hardware” PIM which is used to accommodate an MP,
FPs, IP PADs, legacy LT cards, AP cards, and power supply units. One Physical PIM provides
up to 64 LT ports and up to 8 Physical PIM’s can be accommodated in a Stand Alone system.
A Virtual PIM is a “software” PIM and provides up to 64 ports per PIM for use by system
programming as DtermIP telephones, Wireless PS stations or Peer to Peer (PTP) CCIS trunks.
The system consists of up to 16 PIM’s, by the combination of Physical PIM’s and Virtual PIM’s,
thus providing 1020 ports. When the use of Virtual PIM’s exceeds 8 then the number Physical
PIM’s is reduced by one for each additional Virtual PIM required.
The illustration below shows examples of 1020-port configuration by the combination of TDM
LT ports, Dterm IP telephones, Wireless PS stations and Peer to Peer (PTP) CCIS trunks.
