EAGLE® XG ENUM Server
High-capacity, Overview
The current worldwide voice over Internet protocol (VoIP) penetration rate is approaching 10 percent,
portability-corrected and it is clear that telecommunications is evolving toward all-Internet protocol (IP) networks. One of
ENUM routing the challenges created by the IP evolution is how to route and terminate calls between the IP and
circuit-switched domains, which utilize different numbering schemes, to enable seamless service
database that delivery. Electronic number mapping (ENUM) in combination with VoIP peering, offers the key to
solve these challenges.
consolidates both IP Product Description
and TDM address Tekelec’s EAGLE XG ENUM Server is a high-capacity, portability-corrected subscriber routing database
(SRDB) that consolidates both VoIP and time division multiplexing (TDM) address information in
information in a single a single network element to enable efficient service routing. The ENUM Server converts a ported
or non-ported telephone number (TN) into a domain name, which is used to retrieve the uniform
network element to resource identifier (URI) of the carrier or network device associated with that TN. Using the ENUM
enable efficient service Server, providers can deploy a hybrid operator/ private Tier 1 ENUM solution to route VoIP calls, short
message service (SMS), multimedia message service (MMS) and future multimedia services within
routing. their own network and across other operators’ networks. The EAGLE XG ENUM Server can help
peering problems for all types of operators – wireless, wireline, cable and non-facilities-based.
The application is built on a highly scalable, high-performance software and hardware architecture
that delivers the transaction rates needed to drive next-generation, SIP-based networks.
