Figure 18: S8700 Multi-Connect in a standard reliability configuration
Figure notes:
1. The Administration PC accesses the S8700
series Media Server over the corporate data
network.
2. Corporate IP network.
3. Corporate IP network interface. The Ethernet 4
link from the S8700 to the data network.
4. Two S8700s are always present. One server is
in active mode, and the other server is on
standby.
5. Duplication interface, default Ethernet 2. The
dedicated Ethernet connection between the
S8700 Media Servers.
6. Services interface, default Ethernet 1. The
server's dedicated Ethernet connection from
the S8700 to a laptop computer (active only
during on-site administration or on-site
maintenance).
1. The Ethernet connection to the corporate network in this figure is a nondedicated network. IP addresses for the various
components of the S8700 Multi-Connect Media Server must be administered to prevent conflicts with other equipment
that shares the network. In the default S8700 Multi-Connect configuration, all other Ethernet connections operate on
their own closed LANs.

7. Network control A interface, default Ethernet 0. The
server's Ethernet connection to one or two Ethernet
switches. This Ethernet link carries the control signals for
the S8700 Multi-Connect PNs.
8. Ethernet switch. At least one Ethernet switch is required
1
to support the S8700 Multi-Connect control network. If
many PNs are present, two Ethernet switches can be
daisy-chained together to provide sufficient Ethernet
connections to the IPSI boards in the PNs.
9. UPS. Keeps the S8700 Media Servers and the Ethernet
switches functional during brief power outages.
10. PN. Provides the telecommunications functions of the
S8700 Multi-Connect Media Server.
11. IPSI. The IPSI circuit pack carries the control network
signals to the PNs, and provides tone clock functionality.
12. Bearer connectivity over Center Stage Switch or ATM.
