NEC Univerge SV8100 System Configuration Manual page 6

Highlights of the SV8100/SV8300 are as follows:
 Pure IP System capable TDM configuration
The SV8100 supports both pure IP switching (peer-to-peer connections) and Time Division
Switching. The pure IP switching is provided for communications between DT700 series
telephones and for CCIS connections with other SV8100/SV8300/SV7000. On the other hand,
the TDM switching is provided for communications between legacy stations/trunks. Connection
between IP network and legacy network is made via VoIP board on the CPU board, which
converts packet-based voice data to TDM-based voice data, and vice versa.
Powerful CPU Board with Built-in Functionalities

The CPU board of SV8100 is a heart of pure IP connections and TDM-based connections. The
CPU board employs a 32 bits microprocessor. With this processing power and DSP technology,
it integrates the following functions.

DTMF receivers

Caller ID receivers

Caller ID senders

MF senders / receivers

In-Mail (VMDB)

VoIPDB
* DB = Daughter Board
In addition, by means of today's advanced LSI technology, size of the CPU board is minimized,
O&M NIC port (10/100M) is built in and VoIPDB which has VoIP NIC port (Gigabit Ethernet) is
mountable without additional slots in the KSU. The O&M NIC port is linked with LAN / WAN for
inter-work with PCPro, SMDR, OAI server, and the VoIP NIC port is linked with LAN / WAN for
control signaling and voice signaling (RTP) for DT700 series, etc.
CPU Board Interface :
- O&M Ethernet port （10/100M）
- USB V1.1 (HOST)
- Audio In/Out （External MOH/BGM Input / External Paging out） - 2 port
- General Porpous relay contact
IPLA (VoIPDB) Board Interface : 32/64/128 channel VoIP gateway
- G711,G729,sRTP (G729+sRTP ; max 24/48/96 channel)
- VoIP Ethernet port (Giga-bit Ether)
 High Density Legacy Line / Trunk Boards
Major legacy line/trunk boards used in SV8100 is provided with main board + daughter board
architecture. When the main board is only mounted in an initial supply, line/trunk interfaces can
be easily expanded by adding the daughter board. The maximum number of ports for the line /
trunk boards is 16/8 ports with daughter Board, respectively. This allows the physical system
size to be compact.
 Universal Board Slot (9.5" KSU and 19" KSU)
9.5" KSU and 19" KSU is used for legacy line / trunk boards. One 9.5" KSU provides 3 board
slots and 19" provides 6 slots. Also, these board slots can be used for in-skin application boards
without complicated limitation. As this makes easy quotation and installation.
