Using LANs with GDI

The Generic Data Interface (GDI) allows TCAP to run over TCP. This allows TCAP applications to communicate using an IP network.

GDI supports one or two signaling LANs. Each LAN interface used by a system must be configured on a different subnet.

LANs used by GDI must be dedicated to GDI. The IP addresses of GDI signaling LAN cards should not be configured in the /etc/hosts configuration file because GDI LANs are identified in HP OpenCall SS7 by their IP addresses (the IP addresses are configured in the SS7 Stack Monitor). Declaring these addresses in /etc/hosts or any other name resolution service (such as DNS) will cause the system to use these addresses for non-GDI traffic.
