Duplex Reliability when sending voice bearer
over IP
The S8700 Media Server is duplicated. Tone-Clock functionality is provided by the IPSI circuit pack in
each PN. As an all-IP solution, only IP-connected port networks are supported.
The duplex-reliability option is the most basic option. A duplex-reliability configuration consists of the
following:
• Two S8700 Media Servers
• One Ethernet switch
• One UPS unit for each S8700 Media Server. The use of two UPS units ensures that a single UPS
failure or repair operation will not disable the system.
• One IPSI in each IPSI-connected port network.
See Figure 5, Duplex-reliability configuration when sending voice bearer over IP,
on page 15 for an
example of a duplex-reliability configuration when sending voice bearer over IP.
