80 Avaya Application Solutions IP Telephony Deployment Guide
Because the inter port network TDM traffic flow is supported by a Center Stage Switch (CSS) or
an Asynchronous Transfer Mode (ATM) switch using fiber-optic cables, this configuration is
called fiber-PNC. The call control traffic between the server and the gateways is usually, but not
necessarily, over a private dedicated Ethernet network that is provided by Avaya.
This solution is scalable to up to 44 port networks (PNs) through CSS configuration, and up to
64 PNs in an ATM configuration. The fiber-PNC solution has three reliability options:
● Standard. Duplicated S8700-series Servers with memory shadowing, two uninterruptible
power supplies (UPS), one Layer-2 Ethernet switch, and one IPSI in each IPSI-connected
PN.
● High. Standard reliability, plus a second Layer-2 Ethernet 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.
S8720 and S8730 Servers
The Avaya S8720 and S8730 Server Platforms are high-performance servers with AMD
Opteron processors running Avaya Communication Manager software. The S8720 is a
replacement server for the S8700 and S8710 Servers and the S8730 is a replacement for the
S8720 Server. The S8720 and S8730 support a software duplication option that eliminates the
need for the DAJ1 and DAL1 or DAL2 hardware-assist duplication cards.
The S8720 and S8730 systems support the Avaya MCC1, SCC1, CMC1, and G650 Media
Gateways. The Avaya G700, G450, G350, G250, and G150 Media Gateways are also
supported if there is a TCP/IP connection between the media gateway and a C-LAN circuit pack
located in a MCC1, SCC1, CMC1, or G650 Media Gateway. The S8720 and S8730 have the
capacity to support up to 64 port networks.
The S8720 Server is available in two configurations:
● Standard configuration.
● Extra large configuration that provides higher capacities.
The S8730 Server is available in a single extra large configuration with 4 GB of RAM and RAID
controllers and an optional duplicated hard disk.
S8700-series Servers
Table 4: Avaya Application Solutions comparison matrix — components, performance, and
capacities on page 34 summarizes the performance and capacity specifications of the Avaya
S8700-series Servers.
The Avaya S8700-series Server platform always consists of two servers running on a Linux
operating system. In S8700-series fiber-PNC and IP-PNC configurations, the S8700-series
Server provides the main feature and management processing capabilities of the system. The
server is connected to other system and external components primarily through IP networks.
