This solution is scalable to up to 44 Port Networks (PNs) through CSS configuration, and up to
64 PNs in an ATM configuration. The Multi-Connect solution has three reliability options:
Standard. S8700 series Media Server, with memory shadowing, two uninterruptible power
supplies (UPS), one switch, and one IPSI in each IPSI-connected PN
High. Standard reliability, plus a second switch and a second IPSI in each IPSI-connected
PN. This design provides for a second redundant call control network
Critical. High reliability plus duplication of the bearer network

Multi-Connect
S8700 series Media Server
The Avaya S8700 series Media Server always consists of two Intel-based servers running on a
Linux operating system. In S8700 Multi-Connect and IP-Connect configurations, the S8700
Media Server provides the main feature and management processing capabilities of the
system. The Media server is connected to other system and external components primarily
through IP networks.
S8700 external features
Six 10/100 Ethernet NICs per server, which are used as follows:
- Dual control network connections
- A heartbeat link to the duplicated server
- Administrative access from the corporate network
- Technician access
- One unused

1. The information in this table represents the maximum number of calls
the S8700 Media Server can execute when unconstrained by other
factors such as TDM bus limitations, call duration, or a small number of
telephones. We assume processor occupancy of 0.90, at which various
delay criteria such as cut through is preserved, and is just at the
threshold where call shedding would commence.
