The SFVRA-CFG Network
As shown below, an SFVRA-CFG network is composed of multiple sites that are attached via WAN
circuits.
Through configuration, the SFVRA-CFG network can be subdivided into connection groups. These
are groups of sites that can communicate with each other. Within each group a star network is
normally defined. This means that there is one designated central site, and the rest of the sites in
the group are considered “Remotes.”
The following graphic illustrates the connection group concept.
A site can have one or more systems. The systems are normally viewed as one system by other sites.
This means that they can share a device authentication system name and authentication password/
secret. They may optionally be connected to a multi-line hunt group. In a hunt group, all systems
can share one phone number.
A system is a communication device that implements PPP (Point-to-Point Protocol) or Combinet
Proprietary Protocol (CPP). It can be a communicating host (such as a PC with a modem) or a
remote LAN with an attached bridge or router.
