Firmware Processor (Fp); Reduced Hardware With Ip Based Architecture; Universal Slot; Unified Circuit Card Size - NEC SOPHO 2000 IPS User Manual

General Product Description
Authentication. Also, the built-in DRS can be inter-worked with DHCP server to provide
easy administration on IP address.

1.4.2.1 Firmware Processor (FP)

The Firmware Processor card (FP) provides Line/Trunk interface, Memory (RAM 768
KB), and inter-module BUS interface. BUS interface functions as a driver/receiver of
various signals, adjusts gate delay timing and cable delay timing, and monitors I/O Bus
and PCM BUS. When the system consists of three PIMs or more, one each of this card is
mounted respectively in PIM 2, PIM 4, and PIM 6.
The first FP to service PIM 0 and 1 is incorporated in the MP.

1.4.3 Reduced Hardware with IP based Architecture

The DtermIPs connected to the LAN do not require DLC cards because they can be
interfaced directly with the LAN and connected with peer-to-peer basis. When the
DtermIP is connected to a station/trunk that is using TSW, the speech path between LAN
and TSW is made via IP PAD under the call processing control of the MP. The DtermIP
can be expanded simply adding the terminal itself and IP PAD if traffic volume is
increased. With this system architecture, the hardware such as DLC, PIM, Power Supply
etc. is reduced and easy moves, adds, and changes can be realized.
Standard TDM Hardware:
- Line & Trunk Cards
- Application Processors
- Firmware Processors
Peer to Peer IP Hardware:
- SPN-8IPLA IP PAD
- PZ-M606-A
- PN-24IPLA IP PAD (The PN-24IPLA is a daughter board for the 8IPLA for up to 32
IP PADs)

1.4.4 Universal Slot

One PIM provides 12 card slots for Line/Trunk (LT). Also, these card slots can be used
for Application Processor (AP) cards without complicated limitation. This makes easy
quotation and installation, and more AP cards can be mounted in one PIM.

1.4.5 Unified Circuit Card Size

All circuit cards for the SOPHO 2000 IPS are designed in one size (PN-type), and
installed in the PIM. This maximizes the efficiency of slot utilization of the PIM.

High Density Line/Trunk Cards

1.4.6 High Density Line/Trunk Cards
The major line/trunk cards used in the SOPHO 2000 IPS are provided with 8 circuits per
card. This allows the physical system size to be compact.
