S8700 Multi-Connect configuration for higher availability
When used with the MCC1, SCC1, G700, or G350 Media Gateways, the S8700 series Media
Server has the following reliability options:
Standard reliability configuration
High reliability configuration
Critical reliability configuration
Standard reliability configuration
The standard reliability option is the most basic option that consists of the following
components:
Two S8700 series Media Servers
Server-to-IPSI control is not duplicated
One UPS unit for each S8700 Media Server. Using two UPS units ensures that a single
UPS failure or repair operation does not disable the system.
One IPSI in each IPSI-connected port network
Circuit-switched traffic between port networks is carried on a simplex network that is made
up of one Expansion Interface (EI) in each port network. The EIs are cabled with lightguide
fiber to either the Center Stage Switch (CSS) or an Asynchronous Transfer Mode (ATM)
switch.
