Introduction

The IP⁷ Secure Gateway functionality in the EAGLE provides connectivity between SS7 and IP networks, enabling messages to pass between the SS7 network domain and the IP network domain, as follows:

• When an EAGLE receives an SS7 formatted message over an SS7 link, the IP⁷ Secure Gateway functionality dynamically converts this message into IP format and routes the re-formatted message over an associated IP link to a destination residing within an IP network.

  The IP⁷ Secure Gateway functionality use associations to access the IP domain. Associations identify IP sessions.

• Conversely, when the EAGLE receives an IP formatted message over an IP link, the IP⁷ Secure Gateway functionality dynamically converts this message into SS7 format and routes the re-formatted message over an associated SS7 link to a destination residing within the SS7 signaling network.

  Address resolution is not performed in the IP to SS7 direction. It is the responsibility of the sending application to ensure that the appropriate SS7 point code information resides in the IP message to allow a valid SS7 message to be constructed for routing to the SS7 network.
