Next Generation Platform
The IP-PBX 7070 provides, through an IP-based feature server, a pure IP solution where the mail server, Session Initiation Protocol (SIP) server and Voice Messaging System (VMS) function. The IP-based feature server uses the Linux platform and allows the user to continually add the feature server modules to be provided in the future.
High Quality IP Phone Function
The IP-PBX 7070 separates the priorities and groupings of data and voice packets to guarantee the following Quality of Service (QoS) in voice calls.
Layer 2 QoS: Priority Processing(802.1 p), VLAN(802.1 q)
Layer 3 QoS: CBQ(Class Based Queuing), RTP(Real-time Transmission Protocol) Priority Queuing, On-Demand Bandwidth management for WAN
Wireless LAN Service
IP-PBX 7070 provides the wireless LAN solution for wireless/wired complex service in office zone. The data is separated from the voice, and the handoff and QoS functions are supported using a base station (DUAL AP, Access Point) providing services. IP-PBX 7070 uses wireless LAN base station so that IP-PBX 7070 can serve wireless/wired voice/data communication and internet access function. Also, an efficient and convenient working environment can be made at any time or place because sophisticated mobile stations are used for IP-PBX 7070.
A Variety of Application Solutions
IP-PBX 7070 offers a variety of application solutions such as IP-PBX News, IP-PBX EasySet, Internet Call Center, R-NMS, Voice Mail System, Integrated Fax Server, and Digital Integrated Recording Systems.
Ease of Installation and Expandability
The IP-PBX 7070 has a single cabinet architecture and is installed on a wall.
Because of its attractive appearance, it looks good enough to install in an office. The user can expand it by installing multiple service boards additionally into universal slots.
System Architecture
The IP-PBX 7070 is composed of the basic cabinet, to be installed on a wall, and the IP-PBX Feature server, to be installed in an external Linux server. The main part (Basic Main Processor, Main Block) of the BMP board, which is the main control block, is installed within the basic cabinet to manage the overall operations of the IP-PBX 7070 and perform the switching, signal processing, and terminal management functions. In addition, the B8S part (Basic Main Processor, 8SLI Block) and E8S board (Extended 8SLI Board) are designed to allow the user to mount various optional boards onto them.
The service configuration diagram of IP-PBX 7070 system is shown in the figure opposite:
Voice Trunk Part
The voice trunk part is composed of digital and analog trunks.
The PRI Module (PRM) provides the Primary Rate Interface (PRI) digital trunk function, sending and receiving voices through a trunk and transmitting 64 kbps data packets per channel. The 4-Port Trunk Module (2BRM, 4TRM) provides the Polarity Reverse Signal (PRS) and Caller ID (CID) Path functions within a board by default.
Voice Station Part
The voice station part is composed of the Digital Line Interface (DLI), which is a digital station, and the Subscriber Line Interface (SLI), which is an analog station, to provide voice services. Depending on the number of ports and the combination of stations, multiple station boards can be installed. A 4DLM board is used for a digital station and a 4SL2 board an analog station.
Voice Application Service Part
The voice application module is composed of the Voice over Internet Protocol (VoIP), which transmits voices to the data network, and the Wireless Local Area Network (WLAN), which transmits voices wirelessly. The Media Gateway Interface (MGI) refers to the application that converts voices to data, thus providing the VoIP function. The MGI is supported by the processor by default without requiring any additional module.
Application Configuration
The IP-PBX 7070 has a commercial Windows platform server outside the cabinet and provides the following application software. In contrast, OSDM (Management), SMDR (Billing), Xchange (AA, VMail, Email, Fax Mail, Recording, …)
