CSX200 and CSX400 WAN Configuration

as the backup. If the primary link should fail for some reason, the other WAN interface will take over as the wide area link until the primary is restored.

When a WPIM-S/T is installed as the backup interface, that connection will activate and provide an ISDN connection to the wide area network, if the primary WAN link fails. The ISDN WPIM can also provide backup for single or multiple Data Link Connection Interfaces (DLCIs). If a leased line loses a DLCI or a remote ofÞce, for example, the WPIM-S/T will restore a 64K connection for that site while the rest of the connections remain on the leased line. For more information on WAN redundancy and the WPIM-S/T, consult your QuickSET documentation or your hardware documentation.

NOTE

The WPIM-S/T is designed for WAN ISDN redundancy only and is not intended to be used for a primary WAN connection at this time.

CSX WPIMs

The following Cabletron WPIMs provide WAN connectivity for the CSX400, HSIM-W84, and the CSX200 series. Currently Cabletron recommends that all WPIM conÞguration be done through the QuickSET application that was shipped with your device. Consult your QuickSET documentation for more details.

If there is a speciÞc device from the CSX200 series that supports the WPIM, it is noted below. Otherwise, the WPIM can be special-ordered and installed in a general CSX200 (contact the Cabletron Systems Global Call Center for more information).

WPIM-DDS

DDS is Digital Data Services, a digital network that

 

supports data rates of 56Kbps or 64Kbps. The DDS

 

service provides users with dedicated, two-way

 

simultaneous transmission capabilities operating at

 

transfer rates up to 64 Kbps. This WPIM comes with a

 

built-in CSX/DSU. (CSX203)

WPIM-DI

The DI (Drop-and-Insert) WPIM provides a T1 interface

 

through a front-panel RJ45 port and includes a built-in

 

CSU/DSU for direct connection to a T1 line. The WPIM-

 

DI provides Full T1 or Fractional T1 using 56 or 64 Kbps

 

Time Slots. It also provides a second Drop-and-Insert

 

interface that allows more than one device, such as a

 

PBX, to share a single T1 connection. (CSX201)

WPIM-E1

This WPIM provides an E1 interface through a front-

 

panel RJ-45 port and includes a built-in CSU/DSU for

 

direct connection to an E1 line. This WPIM provides Full

 

E1 or Fractional E1 using 56 or 64 Kbps Time Slots with a

 

total throughput of up to 2 Mbps. Time Division

CSX200, CSX400 specifications

Cabletron Systems was a leading developer of networking solutions, and its CSX400 and CSX200 series of high-performance switches represent some of the key innovations in the field of enterprise networking during their time. Both models were geared towards enhancing network reliability, efficiency, and speed, particularly in environments where heavy data traffic and complex networking demands were prevalent.

The CSX400, designed for larger enterprises, boasts a robust architecture capable of handling significant throughput. One of its standout features is its stackable design, allowing multiple switches to be interconnected and managed seamlessly as a single unit. This scalability provides organizations with the flexibility to expand their networks without significant infrastructure overhauls. The CSX400 supports various Ethernet standards, including 10/100 Ethernet and Gigabit Ethernet, positioning it to effectively manage both legacy and modern networking requirements.

In addition to its scalability, the CSX400 is distinguished by its advanced Layer 2 and Layer 3 routing capabilities. This dual-layer functionality enables efficient data handling and is instrumental in managing traffic between different network segments. Moreover, the switch incorporates features like VLAN (Virtual Local Area Network) support and Quality of Service (QoS) prioritization, allowing for enhanced performance of critical applications and streamlined bandwidth allocation.

On the other hand, the CSX200 series is tailored for smaller enterprises or branch offices needing a reliable yet efficient networking solution. Despite its compact design, the CSX200 is equipped with essential features that promote effective network management and security. It offers a simplified management interface, making it user-friendly for network administrators. The switch also provides essential access control measures, employing technologies like IEEE 802.1X for network access security.

Both the CSX400 and CSX200 prioritize performance through the incorporation of advanced switching technologies. They support features such as Spanning Tree Protocol (STP), enabling loop-free topologies and enhanced network resilience. These attributes are particularly crucial in dynamic networking environments where downtime can have significant repercussions on business operations.

Overall, Cabletron Systems' CSX400 and CSX200 series represent a blend of scalability, advanced routing capabilities, and user-friendly management, making them vital assets for organizations looking to optimize their network infrastructure during a period of rapid technological evolution. With their rich feature sets and unwavering performance, these switches helped pave the way for modern networking solutions that cater to diverse enterprise needs.
