Basic Server and IPSI Connectivity
The S8700 Media Server uses IPSIs to control port networks and provide tone,
clock and call classification services. The IPSI board connects to the control
network via Ethernet. IPSIs are described in more detail in Getting Started with
the Avaya S8700 Media Server.
High-Reliability Connectivity
In a high-reliability Multi-Connect configuration there are duplex media servers,
duplex control networks, and duplex IPSIs in each of the IPSI-connected port
networks. However, the bearer network is not duplicated. This is shown in
. The control network is duplicated so that a single fault in the
control network, such as a bad Ethernet switch, will not bring the whole system
down.
Each of the media servers connect to each of the control networks via the
Ethernet switches. Each of the Ethernet switches connect to each of the IPSIs in
the port networks. Each of the port networks connect to the single bearer network.
A port network can be IPSI-connected or non-IPSI-connected. In the high
reliability configuration, all IPSI-connected port networks must have duplicated
IPSIs. The non-IPSI-connected port networks will have nonduplicated Tone/Clock
boards.
Critical-Reliability Connectivity
In a critical-reliability configuration there is full duplication of all duplicateable
options: media servers, control networks, IPSIs, and bearer networks. The
addition of duplicated bearer networks requires that each port network be
connected to each bearer network. As with the high-reliability configuration, this
configuration also requires that IPSI-connected port networks have duplex IPSIs.
This configuration additionally requires that the non-IPSI-connected port networks
have duplicated Tone/Clock boards (either TN2182 or TN780).
