Getting to Know Your G.SHDSL CSU/DSU
This chapter covers the key features and main applications of your Prestige.
The Prestige 724 is a CSU/DSU designed for small offices and branch offices to provide cost-effective
access to high-speed G.SHDSL service. The Prestige is interoperable with frame relay and PPP routers via
the Data interface. The Prestige offers both LAN-to-LAN and Internet access applications using your
existing phone line.
1.1 Features of the Prestige
The following features make the Prestige a complete and flexible networking solution for most users.
Data Port Interface
Connects to a PPP/Frame Relay router and allows the router to use broadband service.
High Speed Scalability
One of the best features of G.SHDSL service is its scalability. Your Prestige G.SHDSL CSU/DSU supports
symmetrical multi-rate data transmission speeds from 144 Kbps to 2320 Kbps. You can increase the
capacity of the Internet connection (within certain distance limitations) without changing your ISP or
purchasing new equipment. G.SHDSL’s high symmetrical speeds are ideal for applications like web hosting
and videoconferencing as well as the two-way data traffic needs of businesses.
Symmetrical High Speed Internet Access
The Prestige 724 supports symmetrical transmission rates of up to 2.3 Mbps. For NSP’s (Network Service
Provider) convenience, the Prestige also supports rate management depending on distances and service
charges.
