Your SPMA for the CSX200 and CSX400 management modules provides
management support for both the CyberSWITCH CSX200 and CyberSWITCH
CSX400 stand-alone LAN-to-WAN access devices. Both the CSX200 series and the
CSX400 device support PPP and Frame Relay WAN protocols, as well as
multiprotocol bridging and IP/IPX routing.
The CSX200 series (CSX 201, 202, and 203) is designed for smaller branch ofÞces
who need up to twelve Ethernet ports connected to a corporate WAN or ISP. Each
CSX200 device has twelve RJ-45 ports and one WAN interface. Before shipping,
the proper Wide Area Port Interface Module (WPIM) is installed in your device,
depending on the technology you need. WPIM connections currently supported
by SPMA include T1 and synchronous. In the future E1, DDS, DI (Drop-and-
Insert), and HDSL will also be supported by SPMA. All of these WPIM options
are discussed in Chapter 2,
Device ConÞguration . The CSX200 also supports
Point to Point Protocol (PPP), leased lines, and Frame Relay (RFC1490), providing
up to four Permanent Virtual Connections (PVCs) to corporate ofÞces or the
Internet.
The CSX400 is ideal for corporate ofÞces or larger branch sites that require two
individual Ethernet LAN segments with single or dual WAN connectivity. The
two Ethernet ports can be conÞgured with any available EPIM media, while the
two WAN ports can be occupied by any swappable combination of Cabletron
WPIMs. Currently SPMA can only manage a T1 or synchronous connection, but
in the future WPIM options for SPMA will also include DDS, DI, E1, and HDSL
connectivity. Each WPIM can act independently, allowing simultaneous
communication, or the pair can be conÞgured to provide redundant channels if
desired. Connectivity is available for Point to Point Protocol (PPP), as well as
Frame Relay and leased lines.
