H.323 GATEWAY SERVICE
This service can be implemented in 2 ways:
- using Alcatel OmniPCX Office as a router to the Internet with integrated Proxy and Firewall; in this
case, a CoCPU@ board is necessary;
- using an external router to the Internet or to a dedicated link providing the same level of service as
the Office R42 range.
Nota : In the following diagrams, Alcatel OmniPCX Office is used for the Internet connection con-
figuration and the external router is used for other types of connection (leased line, ADSL,
etc.).
The Alcatel OmniPCX Office H.323 Gateway service can be implemented in either of 2 contexts:
- H.323 gateway integrated into a standalone configuration.
- H.323 gateway integrated into an H.323 zone.
H.323 gateway integrated into a standalone configuration
In a standalone configuration the integrated gatekeeper is alive; it is masked to the exterior and cannot
be managed from the
LAN.
Nota : - The integrated gatekeeper does not manage H.323 zones.
- In this topology, only the PCs with NetMeeting and equipped with the Alcatel secure plug-
in can make PC to Station calls.
