General Product Description

1.4 Hardware Architecture

1.4.1 Hybrid System of IP (peer-to-peer connection) and TDM Switching

The SOPHO 2000 IPS supports both pure IP switching (peer-to-peer connections) and
Time Division Switching (TDM). The pure IP switching is provided for communications
between DtermIPs and for CCIS/Remote PIM connections with another SOPHO 2000
IPS/ SOPHO 2000 IPS DM/ SOPHO 2000 IPS DML/ iS3000. On the other hand, the
TDM switching is provided for communications between legacy stations/trunks.
Connections between DtermIP/CCIS or Remote PIM over IP and legacy stations/trunks
are made via IP PADs, which converts packet-based voice data to TDM-based voice data,
and vice versa.
1.4.2 Powerful, One-board Main Processor (MP) with Integrated
Functionality
The SOPHO 2000 IPS Main Processor (MP) is the heart of pure IP connections and
TDM-based connections. The MP employs a high-speed CPU, which is equivalent with
Pentium. With this processing power and System On Chip (SOC) technology, the MP
integrates Device Registration Server (DRS), AP01 (OAI) functions, which are provided
by an additional card in the previous IVS series. Also, by means of today's advanced LSI
technology, the MP card size is minimized and On-board Ethernet Interface card is
mounted on the MP without using an additional slot space in the PIM. This interface card
is linked with LAN for call control processing of DtermIP and inter-work with
MATWorX and OAI server.
The MP provides:
- LAN control function,
- System-based Device Registration Server (DRS),
- Built-in FP,
- Built-in OAI,
- Built-in SMDR,
- Built-in CCH-IPT,
- 33 MHz PCI BUS,
- Memory (Basic/Expansion),
- TDSW (1024 CH × 1024 CH),
- 16-line CFT,
- PB Sender,
- Clock,
- PLO two ports (Receiver Mode/Source Mode),
- two RS-232C Ports,
- two-line DAT (Recording duration: a maximum of 128 seconds),
- DK,
- 4-line PB Receiver,
- Modem for remote maintenance (33.6 kbps),
- internal Music-on-Hold Tone,
- BUS Interface.
BUS Interface functions as a driver/receiver of various signals, adjusts gate delay timing
and cable delay timing, monitors I/O Bus and PCM BUS. One card is required per
system.
The SOPHO 2000 IPS incorporates DRS (Device Registration Server) on the MP. DRS
provide Log-in/Log-out management of DtermIP including Registration and
