NTEROPERABILITY
Interoperability is the ability to operate and exchange information in a heterogeneous network.
SFVRA-CFG supports interoperability with many different remote devices over ISDN.

ROTOCOLS
In order to communicate with various remote devices over ISDN, the SFVRA-CFG must identify
the device type and the line protocol it is using.
The line protocols supported are:
•
Combinet Proprietary Protocol (CPP) Ethernet Frames
•
Point-to-Point Protocol (PPP) Encapsulation for IP Datagrams
The PPP protocols supported are:
•
LCP (Link Control Protocol)
•
MLP (Multilink Protocol)
•
Authentication Protocols
CHAP (Challenge Handshake Authentication Protocol)
PAP (Password Authentication Protocol)
•
NCP (Network Control Protocols)
IPCP (Internet Protocol Control Protocol for TCP/IP)
IPXCP (Internetwork Packet Exchange Control Protocol for IPX)
BCP (Bridge Control Protocol for bridges)
ATCP (AppleTalk Control Protocol for AppleTalk Routing)
•
CCP (Compression Control Protocol)

NTEROPERABILITY
The remote devices that connect to Cabletron's CyberSWITCH or SmartSwitch Remote Access
Module can be classified into three types:
•
MAC Layer Bridges (PPP or HDLC)
•
IP Host Devices (PPP)
•
IP Router Devices (PPP)
MAC layer bridges connect to the Cabletron systems using either HDLC or PPP.
IP Host devices are single workstations or PCs that connect to the Cabletron systems at the IP
network layer. These devices use PPP to communicate with the systems.
IP router devices are single devices that represent many other IP hosts and routers to the Cabletron
systems. They must use the CHAP or PAP protocol to identify themselves to the system. IP routers
usually provide IP network address information at connection time (and use PPP to send user data
to the Cabletron systems).
