The CSX7000, the high availability, remote access switch, is a multi-system platform intended for
large, central sites and Internet Service Providers. It is both modular and flexible, with capabilities
and performance to match the requirements of high-end network connectivity customers. The
CSX7000 supports a high density of LAN segments, ISDN BRI or PRI, and digital modems, as well
as RS232, V.35, Frame Relay and X.25 interfaces. It also offers an effective means of system
management through its optional Environmental Management System (EMS) module.
Modularity: An important feature of the CSX7000 is its ability to support multiple system groups.
Each group is a stand-alone CSX “system” based on a Pentium processor module. Use the sixteen
ISA slots of the CSX7000 as a single system group, or partition it into as many as four system
groups. A combination of modules (including a processor module) makes up a system group.
Flexibility: The CSX7000 supports a flexible setup for system groups; mix and match individual
LAN and WAN interface modules within a group to support specific needs.
High Availability: Local Area Network (LAN) and Wide Area Network (WAN) interface modules
have their own dedicated on-board processors and memory, thus lessening the load on the main
processor. TDM and MVIP bus connections allow the transfer of data between cards to improve
throughput without using the ISA bus.
The fault-tolerant platform provides redundant, hot-swappable power supplies and cooling fans.
The platform supports bus segmentation and load sharing. For backup or parallel operations,
configure redundant system groups.
Environmental Management: The platform contains intelligent environmental sensors to monitor
power, temperature and other environmental functions.
