Avaya 555-245-600 manual Avaya S8700-series Server IP-PNC configuration

Avaya Application Solutions platforms

Critical reliability configuration

The critical reliability configuration option is built upon the high reliability configuration. In the critical reliability configuration, the bearer network has duplicated components so that there is no single point of failure. The critical reliability configuration consists of the following components:

●Two S8700-series Servers

●Two IPSI circuit packs in each IPSI-connected port network

●Two Ethernet switches

●Two UPS units

●Two CSS/ATM EI (Expansion Interface) in every port network

S8700-series fiber-PNC survivability

In addition to the high reliability of the duplicated S8700-series Servers, the S8300 or S8500 Server in a Local Survivable Processor (LSP) configuration can be used to provide survivability for H.248 branch gateways and IP phones. Additional recovery capability is embedded in the Communication Manager that resides on the S8700-series Server.

The S8500 and S8700-series Servers provide survivability for remote G650 Media Gateways and port networks with IPSI.

Avaya S8700-series Server IP-PNC configuration

The S8700 IP-PNC configuration is an all-IP solution that is built on open IP network connection. This solution is designed for medium to large enterprises. The main difference between the IP-PNC and fiber-PNC configurations is that IP-PNC uses the IP network for all inter-port network communication whereas fiber-PNC uses optic-fiber connections between the PNs in a CSS or ATM network.

The IP-PNC platform is scalable to 64 Port Networks, each of which can house up to five G650s and up to 250 G700, G450, G350, G250, or G150 Media Gateways. The server complex still consists of duplicated S8700-series Servers. One server is active, and the other server is on standby. See Table 4: Avaya Application Solutions comparison matrix — components, performance, and capacities on page 34 for information on the S8700-series Server performance and capacities.

Figure 30: Avaya S8700-series Server with remote G650 / G700 / G350 Media Gateways on page 97 shows an example of an S8700 with remote G700 Media Gateways.
