S8700-series / G650 IP-PNC
The S8700-series IP-PNC system (Figure 36: S8700-series IP-PNC system on page 114) is a
scalable solution that supports up to 64 G650 Media Gateways in stacks of from one to five
rack-mounted G650 cabinets. See Table 4:
Avaya Application Solutions comparison matrix —
components, performance, and capacities on page 34 for capacities information for the
S8700-series IP-PNC system.
The S8700-series Servers can be networked with other systems through IP or circuit-switched
trunks to provide for significantly larger telephony networks. The control link between the
servers and the Media Gateways traverses the enterprise IP network. All G650 Media
Gateways require IPSI circuit packs to provide the Gateway’s control link. There is no traditional
circuit switch (Center Stage Switch), and the media traffic flow is entirely through the enterprise
data network. Each G650 has at least one Media Processor circuit pack, which provides the
gateway between the TDM bus and the circuit pack’s Ethernet connection for the audio
streams. Each G650 also has at least one C-LAN, which provides H.323 signaling to IP
endpoints.
