Overview
The Nortel Networks CVX* Multi-Service Access Switch is a high-capacity,
carrier-class, access switch that allows subscribers to connect to a public data
network (PDN). You can access corporate network resources and the Internet
from anywhere in the world through Integrated Services Digital Network (ISDN)
lines or by modem over the public telephone network.
The CVX switch provides an interface between the telephone network and the
data network. When the CVX switch validates and terminates a call, it passes the
call to the designated customer, such as an Internet service provider (ISP),
corporate host, or other network. The CVX switch’s redundant architecture
provides reliable carrier-class performance, which means high availability,
maintainability, scalability, and compliance to carrier standards.
