Reliability levels
Avaya communications systems that are controlled by the S8500 media server have no
duplication. This configuration is sometimes referred to as simplex reliability. Communications
systems that are controlled by S8700-series media servers can have one or a combination of
the following three duplication or reliability levels:
● Duplex
S8700-series media servers that are duplicated, which is the standard configuration
● High
Duplicated media servers and control network.
● Critical
Duplicated media servers, control network, and bearer network.
