Figure 37: S8700-series IP-PNC with remote G700 or G350s
Note:
Note: A typical remote office is configured with a single gateway. Several gateways are
shown in the remote office in Figure 37
to illustrate additional possible
configurations.
S8700-series with G150/G250: large number of remote branches
The newer small gateways G150 and G250 are designed to be deployed individually in large
number (100’s to 1000’s) of small branches, with management and call control centralized at a
headquarter with S8700/S8710 servers. Each branch would have a single G150 or G250 with
2-10 stations (analog, DCP, or IP), and analog or T1/E1 PSTN trunks. Any location needing
more than 10 stations should consider using G350 or G700. G350 is also meant to be deployed
alone at a location; only the G700 should be used in multiple expandable unit configurations.
At each branch, LAN and WAN functions can be provided by external 3rd party or Avaya
networking devices, or as part of the integrated options within the gateways. WAN connection
back to HQ can utilize low cost options such as VPN over public internet via cable or DSL
(G250). Emergency fallback to phone modem is also possible. See Figure 38:
