Avaya Application Solutions platforms
S8700 Media Server Multi-Connect configuration
The Avaya S8700 series Media Server with an MCC1 or SCC1 Media Gateway is targeted at
Avaya's largest customers. These customers are typically experiencing rapid growth, and
looking for ways to consolidate their network. These are customers who require high-end
applications such as DEFINITY Call Center Solutions, CTI applications, Unified Messaging,
multimedia conferencing, and voice/data network integration, and are evolving to an
IP-intensive environment. This solution supports up to 36,000 telephones.
This solution is also targeted at smaller customers who made an investment in DEFINITY, and
are looking for a smooth transition into industry-standard processors that will enable expanded
communications capabilities.
This is a large-office solution with the Media Server in the headquarter locations, with optional
servers/gateways in the branch offices. There is also the option of duplicated headquarters with
branch and remote offices. The Linux-based Media Servers support up to 36,000 stations,
12,000 of which can be IP, and 8,000 trunks, with the capacity limit of 300,000 General
Business call mix BHCC.

Because calls are processed through both IP and traditional circuit switch links, this platform is
called the Multi-Connect Solution. The Media Server and the Gateways call control traffic is
over a private dedicated Ethernet network that is provided by Avaya. The inter-Port Network
TDM traffic flow is supported by a TDM-based Center Stage Switch (CSS), or an Asynchronous
Transfer Mode (ATM) switch.
