Prestige 724 G.SHDSL CSU/DSU

Congratulations on your purchase of the Prestige 724 G.SHDSL CSU/DSU.

The Prestige 724 is a CSU/DSU (Channel Service Unit/Data Service Unit) 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 port interface. The Prestige offers both LAN-

to-LAN and Internet access applications using your existing phone line.

The Prestige supports symmetrical multi-rate data transmission speeds from 144 Kbps to 2320 Kbps. The

actual rate depends on the copper category of your telephone wires, distance from the central office and the

type of DSL service you subscribe to. The Prestige's data port interface enables fast data transfer in either

half-duplex or full-duplex mode depending on your Ethernet network. See the following section for more

background information on DSL.

The Prestige uses TC-PAM line code with echo cancellation for high data rate transmissions over a single-

twisted telephone wire pair without being affected by bridge taps or mixed cable links. It also provides high

immunity from background noise.

Your Prestige is easy to install. You do not need to set any switches to configure it. Manage the Prestige via

the SMT (System Management Terminal) - a menu-driven interface – using a terminal emulator through the

console port.
