System Configuration
The NEAX2000 IVS
2
consists of 1 to 8 Port Interface Modules (PIMs), each PIM will
support up to 64 interface ports to give a maximum capacity of 512 ports per system.
The PIMs are all the same with a universal back plane, which accommodates station
ports, trunk ports, I/O processors, and power supply boards. Each PIM measures 16.9
inches across by 16.4 inches high by 8.8 inches deep (includes front cover). This
compact frame allows the system to be mounted on a wall, in a 19 inch rack, on a
desk/bench, or bolted to the floor.
PIM units contain the following components.
1. Line/Trunk Interface Slots
Line and trunk interface slots house the digital and analog interface cards. The
NEAX2000 IVS
2
uses the PIM-F.
•
The PIM-F has 15 slots. 12 slots (LT00-LT11) each can be used for either LT
or AP cards. 1 dedicated slot (MP12) for MP or FP, 1 dedicated slot (PFT) for
Power Failure Transfer card, and 1 dedicated slot (VM) for voice mail card. 8
port Line/Trunk cards can be mounted in LT00 to LT07 slots. 4 port
Line/Trunk cards can be mounted in LT00 to LT10 slots. LT11 slot is
available for 4 port Line/Trunk cards only when the system is configured with
two or less PIMs.
2. Power Supply Board
Each PIM is equipped with a Main Power Supply card (PZ-PW121) which
converts AC120V/240V (50Hz/60Hz) to -27V DC (4.4A), +5V (7.2A), CR
(38mA), +90V (80MA).
3. Application Processor (AP) and Common Control Slots
Application processor cards use AP slots in each PIM. The number of available
AP slots depends on the PIM number and which common control cards are needed
for that PIM. The PIM-F has up to 12 AP slots. AP Slots are used to house the
processor boards for SMDR, OAI, T1, ISDN, CCIS, and others. Common control
cards such as the CPU, Bus cards, and local processors occupy only a set number
of AP slots.
4. Power Failure Transfer (PFT)
Two methods are used to provide Power Failure Transfer: (1) Using the
designated circuit card (PZ-8PFTB) which mounts in PFT slot of each PIM to
provide up to 64 trunk to station switch over points and (2) Utilizing the front
edge cable and connecting between 4COT card and AUC card.
