Connections to Legacy Stations and Trunks
The IP station can communicate with legacy stations and trunks (including H.323 trunks) via IP-PAD
that converts voice packet data to PCM signals. Call control signals are transmitted to MP over the
LAN, while voice packets are transmitted via IP-PAD. The number of IP-PADs depends on the traffic
volume of connections between the IP station and legacy stations and trunks.
Remote Connections of IP Stations
The IP stations can be located at remote sites over an intranet/internet/PSTN/ISDN via routers. This
allows IP station users at remote sites to use the NEAX 2000 IPS features as same as those at local
site. The number portability among the sites is available, so that the same IP station user can login at
any site, using the single login code and password. The IP station has two operating modes: Local
Connection Mode and Remote Connection Mode. Each operating mode can have individual VoIP
communication parameters such as CODEC selection list and usable bandwidth, so that the
appropriate communication is available even if the IP station user logs in at either local site or remote
site.
