Avaya S8700-series Media Servers
Avaya S8700-series Media Servers
The Avaya S8700-series (including S8720 and S8710) media servers use a standard
microprocessor engine on a commercial server.
The S8700-series media servers use high-speed connections to route voice, data, and video
between the following trunks and lines:
● Analog and digital trunks
● Data lines that are connected to host computers, data-entry terminals, personal
computers, and internet addresses
The S8720 and S8710 media servers are very similar in architecture, components, and
functionality. Both servers support Communication Manager. The main differences between the
two are:
● The S8720 has greater call processing performance than the S8710
● The S8710 uses a Pentium 4 processor, whereas the S8720 uses an AMD Opteron
processor.
● Software duplication is available on the S8720. The S8720 is ordered without the DAL1 or
DAL2 card used for hardware duplication. Hardware duplication, and the DAL1 or DAL2
card, can be purchased as an option for the S8720.
● The S8720 has a third USB port, which is located on the front panel.
Configurations
The S8720 media server is available in two configurations:
● Standard configuration
● Extra large configuration, available with Avaya Communication Manager R4.0 and later
releases. This configuration requires the DAL2 card.
The extra large configuration provides higher capacities.
Both the S8720 and S8710 Media Servers support two types of port network configurations, or
a combination of both:
● Voice bearer over IP (IP-PNC): An all-IP configuration that carries both control and bearer
information.
● Voice bearer over fiber-PNC, with direct-connect expansion interface circuit packs, Center
Stage Switch (CSS), or Asynchronous Transfer Mode (ATM).
