System Architecture
As shown in Figure 1, the SCM Compact consists of the IPX-S300B, gateway, IP phone,
SCM Administrator, and application server.
Data network systems such as switches and routers are basic requirements of the SCM
Compact and are not included as system components.
1.2.1
IPX-S300B
The IPX-S300B uses the SIP protocol to provide IP-PBX call processing functionality and
uses analog extension (FXS), analog trunk (FXO), ISDN-PRI, ISDN-BRI interfaces, etc. to
communicate with the existing voice networks. The product also provides built-in NAT,
DHCP and SBC Lite functions.
1.2.2
Voice Gateways
The voice gateway is responsible for connecting the existing telephone and networks.
It communicates with the existing telephone network (PBX or PSTN) through the PRI
interfaces as well as analog interface like FXO.
The voice gateway acts as a media gateway, which performs the conversion between PCM
data and packet data. It communicates with IPX-S300B over the standard SIP protocol.
The IPX-G5x0 product series can be used as voice gateway.
1.2.3
IP Phones
IP Phone provides general telephone calls on the IP network. For providing basic calling
and supplementary services, IP Phone communicates with SCM Compact (IPX-S300B)
using the SIP protocol (Samsung SIP Extension) that is partially extended from the
standard.
The following types of IP phones are supported by IPX-S300B.
SMT-i6000 Series
SMT-i5343, SMT-i5243, SMT-i5220S, SMT-i5220, SMT-i5210S, SMT-i5210, SMT-
i5264
SMT-i3105, SMT-i2205G, SMT-i2205S, SMT-i2205
IP Video Phone
Video Phone allows voice and video calls over an IP network.
For provision of basic call and additional services, IP Video Phones communicate with the
IPX-S300B using an expanded version of the SIP protocol (Samsung SIP Extension).
Soft Phone
Soft Phone runs on a PC (Personal Computer) as a software program. It allows voice-only
calls or voice and video calls over an IP network.
