System Configurations; Module Configurations - NEC SOPHO 2000 IPS User Manual

General Product Description

2 System configurations

2.1 Module configurations

The SOPHO 2000 IPS uses a modular Port Interface Module (PIM) design, reduced
energy and space requirements, flexible universal port architecture, Flash ROM
technology and high reliability.
The SOPHO 2000 IPS consists of a single or multiple Port Interface Modules (PIM),
depending on the system configuration; there are two types of PIMs; "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. Up to 8 Physical PIMs can be
accommodated in a Stand Alone system. Port Interface Modules can accommodate four,
eight and 32-port line/trunk (L/T) interface cards and the Application Processor (AP)
cards. Because of a highly integrated Central Processor Unit the SOPHO 2000 IPS also
eliminates the need for some separate application processor cards by combining their
functions onto its CPU.
The 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 PIMs, by the combination of Physical PIMs and Virtual
PIMs, thus providing 1020 ports. When the use of Virtual PIMs exceeds 8 then the
number Physical PIMs is reduced by one for each additional Virtual PIM required.out of
1 to 8 Physical PIM.
The PIM has special slots for the CPU and FP cards and 12 universal slots for Line
Terminating circuits (LT) and Application Processor circuits (AP); although the slots can
accommodate both LT and AP cards.
The first PIM (identified as PIM0) contains the CPU and a 1024x1024 TDM switching
matrix, TDSW, with 1024 x 64kbps channels in and 1024 x 64kbps channels out (= non-
blocking).
512 ports of the TDM switch are reserved for
 Line Terminating circuits (LT), for:
o analogue terminals, with 4 or 8 port analogue station cards
o proprietary digital terminals (Dterm digital), with 2 or 8 port digital station cards
o ISDN video and data terminals, 2 circuit ISDN station card; note not suited for S
voice terminals
o analogue trunk lines
 and for IP-PAD Application Processor circuits (AP):
o to address proprietary IP terminals (Dterm IP), accessed via IP Packet
Assembler/Disassembler circuits (IP-PAD) with 8 or 32 channels
o The IP-PAD can be expanded with voice compression circuits (VCT) for IP voice
over WAN – rarely used in a LAN, 16 channels on a card. (for more details on the
IP-PAD card, refer to section 2.8 )
256 ports of the TDM switch are reserved for:
 Application Processor circuits (AP), for:
