S8700 IP Connect duplex configuration

Ethernet connections for a typical Avaya S8700 Media Server for IP-Connect Configuration are described below.

  1. Avaya S8700 Media Server. The server does system initialization and recovery, provides access to the telephony application software, and handles alarming for hardware and software components. Two are always present, one in active mode and the other on standby.

  1. Duplication interface: default Ethernet 2. The dedicated, direct Ethernet connection between the two required Avaya media servers, used to monitor and exchange the state of health of each server.

  2. Services interface: default Ethernet 1. The server's dedicated Ethernet connection to a laptop.

  3. Network control A and corporate LAN interface: default Ethernet 0. The server's Ethernet connection to the port networks and the customer's LAN. In most S8700 IP-Connect configurations, the control signals for the port networks are sent over the corporate LAN (a "shared" or non-dedicated network). They may be routed through various Ethernet switches or routers, depending on the local network configuration.

The IP-connect configuration may be set up to send its control signals over a private LAN. The configuration in this case looks identical to that of a S8700 Multi-Connect duplex configuration, except for the port network configuration (see items 8 and 9 below).

  1. Corporate LAN. The topology for the local area network varies significantly.

If Ethernet switches are part of the switch configuration and report alarms to the servers using SNMP, they must be on the same subnet as the S8700 media servers.

  1. Administration PC. The administrator typically accesses the media servers over the corporate LAN.

  2. UPS. An uninterruptible power supply keeps the S8700 media server configurations functional through brief power outages. One UPS is required per server.

The UPS units must be on the same subnet as the S8700 media servers, and must report alarms using SNMP to their respective servers, in order for the servers to respond correctly to a loss of power.

  1. Port network (PN). Provides the telecommunications functions of the system. An S8700 IP-Connect configuration supports up to 64 port networks. The port networks must be Avaya G600 media gateways, and each port network must contain an IPSI  circuit pack.

  2. IPSI. The Internet Protocol Server Interface (IPSI) circuit pack carries the control network signals to the other boards in the port network.
