SFVRA Connection Manager 15
S YSTEM O VERVIEW
Interoperability Overview
• High Availability
SFVRA Connection Manager will initiate a connection to a remote device in the event that an
existing connection to that remote device is lost due to a failure of a locally managed
CyberSWITCH.
• Load Leveling
Incoming calls are evenly distributed between all available CyberSWITCHES within a hunt
group.
• Network Security
The Remote Access Switch ensures proper authentication (PAP, CHAP, CLID, NT or CPP) by
validating the remote system with SFVRA database.
•Pooling
Pooling can be configured system wide resulting in a large decrease of the amount of IP
addresses needed.
• Protocol Discrimination
It is possible for multiple types of remote devices to use the same line. The system can
determine the device type and the protocol encapsulation used by remote devices.
• User Discrimination
Network Administrators can reserve the last analog or digital connections of a specific Remote
Access Switch for specific users. This provides priority for mission-critical personnel.
INTEROPERABILITY OVERVIEW
“Interoperability” is the ability to operate and exchange information in a heterogeneous network.
The SFVRA Connection Manager supports interoperability with many different remote devices
over ISDN.
INTEROPERABILITY PROTOCOLS
In order to communicate with various remote devices over ISDN, the SFVRA-CONN 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
Specific protocols within the line protocols are described in the CyberSWITCH documentation.
