Ethernet 1
1. S8700 Server 1 – two are always
present, one in an active mode and one
on standby.
2. S8700 Server 2 – two are always
present, one in an active mode and one
on standby.
3. Duplication Interface – the Ethernet
connection between the two S8700
servers.
4. Services Interface – the S8700 servers
dedicated Ethernet connection to a
laptop. This link is active only during
on-site administration or maintenance,
and the services interface can link to the
non-active server through a Telnet
session.

5. Connection from the Servers to the Local Area
Network (LAN).
6. UPS units – two required.
7. Local Area Network
8. Port Network – optional configuration of media
gateways that provides increased switch
capacity.
9. IPSI – provides transport of CCMS messages
over IP, allowing the S8700 server to
communicate with the port networks.
10. Media Processor - Provides conversion
between Time Division Multiplexed (TDM) and
