Two Signaling End Points Move from PSTN to IP Using End Office
A more complex scenario arises when multiple signaling end points are to migrate from the PSTN to
an IP network using the End Office feature. Consider
Migrate from PSTN to IP

and so P serves as the adjacent point code for nodes X and Y. The following are key points about this
figure:
Q is not an end office node, and so the EAGLE 5 ISS behaves as an STP for messages originated by
and destined to Q.
Reprovisioning is required in the PSTN, since the Q is now behind P. One example of this is that
the linksets between X and Q and between Y and Q must change.
Traffic between P and Q are no longer routed through X/Y, but are routed within the EAGLE 5
ISS.
The EAGLE 5 ISS Simultaneously Acts as STP and End Office

three IP network elements, only one of which use the End Office feature, and two PSTN network
elements. In addition, a capability point code is provisioned on the EAGLE 5 ISS, thereby allowing
the use of GTT.
