Figure 91: IP-PNC Duplex Reliability - Simplex Control Network<br />

Figure notes:<br />

Ethernet 1<br />

1. S8700 <strong>Server</strong> 1 – two are always<br />

present, one in an active mode and<br />

one on standby.<br />

2. S8700 <strong>Server</strong> 2 – two are always<br />

present, one in an active mode and<br />

one on standby.<br />

3. Duplication Interface – the Ethernet<br />

connection between the two S8700<br />

servers.<br />

4. Services Interface – the S8700 servers<br />

dedicated Ethernet connection to a<br />

laptop. This link is active only during<br />

on-site administration or<br />

maintenance, and the services<br />

interface can link to the non-active<br />

server through a Telnet session.<br />

Area Network (LAN).<br />

6. UPS units – two required.<br />

8. Port Network – optional configuration of<br />

media gateways that provides increased<br />

switch capacity.<br />

9. IPSI – provides transport of CCMS<br />

messages over IP, allowing the S8700<br />

server to communicate with the port<br />

networks.<br />

10. Media Processor - Provides conversion<br />

between Time Division Multiplexed (TDM)<br />

and Internet Protocol (IP) voice signals.<br />
