Figure 139: S8700 IP Connect Duplex Reliability Configuration
Figure notes:
1. S8700 Media Server 1 - two are always
present, one in a active mode and the other
on standby.
6. Ethernet Switch - A device that provides for
port multiplication by having more than one
network segment. In an IP Connect
environment, the Ethernet Switch should
support 802.1 ip/Q, VLAN and 10/100 mbps.
2. S8700 Media Server 2 - two are always
present, one in a active mode and the other
on standby.
7. UPS units - two required.
3. Duplication Interface - The Ethernet
connection between the two S8700 Media
Servers.
8. Port Network - optional configuration of Media
Gateways that provides increased switch
capacity.
4. Services Interface - The S8700 Media
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.
9. IPSI - provides transport of CCMS messages
over IP allowing the S8700 Media Server to
communicate with the Port Networks.
5. Connection from the Servers to the
Ethernet Switch.
