Received SCCP Messages that indicate route-on-global-title are treated as having SSN=0 for remote
application assignment. If a remote application is assigned to SSN=0, then the message is forwarded,
otherwise it is distributed to the local SCCP application. In previous releases, this would occur
only for mis-configured networks. Messages indicating route-on-global-title and intended for the
EAGLE 5 ISS, not the end office node, should be sent to the EAGLE 5 ISS's capability point code.
Received SCCP Messages that lack a Called Party SS are treated as having SSN=0 for remote
application assignment. If a remote application is assigned to SSN=0, then the message is forwarded,
otherwise it is distributed to the local SCCP application.
Received SCCP Messages having a Called Party SS equal to SCMG (SSN=1) are processed and
terminated by the EAGLE 5 ISS, and if SSN=1 has a remote application assigned, the MSU is also
replicated and forwarded to the end office node.
Received SSCP Messages having a Called Party SSN not equal to 0 or SCMG (1) and for which a
remote application is assigned are forwarded to the end office node. Messages received for
unassigned subsystems are distributed to the local SCCP application.
The end office node cannot share SCCP subsystems (other than SCMG) with the EAGLE 5 ISS. If
the end office node assigns a given subsystem, such as LNP, then the subsystem local to the EAGLE
5 ISS cannot receive messages. Remote applications take priority over local applications.
Internal Point Code
To route SS7 messages to the IP address without adding another external point code, the End Office
feature uses an internal point code (IPC). This point code is private to the EAGLE 5 ISS, and the PSTN
has no awareness of it. Its sole purpose is to allow messages destined to the End Office Node to be
routed from the inbound LIM to the IPGWx card (a card running either the SS7IPGW or IPGWI
applications). An IPC must be entered as a destination and must be assigned for each network type
having an end office node. This point code is also used internally by the EAGLE 5 ISS in order to route
inbound messages to the outbound IPGWx card. The EAGLE 5 ISS can have up to three IPCs, one for
ANSI, one for ITU International, and one for ITU National networks.
