Signal Transfer Point

The STP is connected to adjacent SEPs and STPs via signaling links.

To meet stringent reliability requirements, STPs are typically provisioned in mated pairs.

Such mesh network configurations are also common in Europe, where STPs have not found widespread deployment[citation needed].

Some examples include: A given piece of equipment can implement both SEP and STP functionality.

In UMTS, the STP provides Global Title Translation (GTT), which may be used to route queries from a gateway MSC (GMSC) to the HLR.
