Avaya Communication Manager and Servers

Figure 73: Isolated LANs (Avaya S8700-series Server with an MCC1 or an SCC1 Media Gateway)

Figure 73: Isolated LANs (Avaya S8700-series Server with an MCC1 or an SCC1 Media Gateway) on page 235 shows how Communication Manager can be configured to allow only certain types of access to specific LAN interfaces on its PNs. For example, even if you connected an administration terminal to one of the other LANs, you cannot get administration access.

S8700-series Server with Avaya G650 Media Gateways

The S8700-series Server with a G650 Media Gateway also have five interfaces each

(Figure 74: Isolated LANs (Avaya S8700-series Server with a G650 Media Gateway) on page 236):

●The enterprise LAN and control LANs are connected together

●There is only one control LAN.

●There are two spare NICs that are not used.

The messages between the S8700-series Server and the G650 are encrypted.
