EAGLE® XG ENUM Server

OverviewThe current worldwide voice over Internet protocol (VoIP) penetration rate is approaching 10 percent, and it is clear that telecommunications is evolving toward all-Internet protocol (IP) networks. One of 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 delivery. Electronic number mapping (ENUM) in combination with VoIP peering, offers the key to solve these challenges.

Product Description

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 a single network element to enable effi cient 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 resource identifi er (URI) of the carrier or network device associated with that TN. Using the ENUM 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 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.

Applicationsoperator eNuM.» The ENUM Server provides a secure, operator-implemented application that can be used between providers for peering agreements. It enables content of any type to be sent from one operator to the next by correlating a TN to a carrier domain. The application provides the access point for the operator of record, not the final private URI of the subscriber. The returned carrier information enables multimedia message servers (MMSCs), call session control functions (CSCFs) or SIP proxy servers to complete calls efficiently and seamlessly.

private eNuM.» Tekelec also supports private ENUM, allowing providers to route services directly to the end client – using the final private URI of the subscriber.

Benefits

improve service routingWith Tekelec’s EAGLE XG ENUM Server, operators can consolidate service routing information in a single, unified database which can be accessed by multiple clients over a variety of query protocols.

Simplify database provisioningBy consolidating subscriber routing information in a single location, The ENUM Server eliminates the need to manage, maintain and update multiple databases.

increase marginsThe ENUM Server enables operators to avoid unnecessary and costly IP to TDM network transitions and local termination charges for calls that originate and terminate in IP networks.

improve QoSThe ENUM Server enables operators to deliver VoIP services seamlessly across IP networks without conversion to TDM.

Lower operational costsTekelec has been providing number portability solutions to global operators for many years. Currently, more than 76 operators in over 26 countries have deployed or ordered Tekelec Number Portability (NP) applications. With this ENUM-based solution and its NP database, Tekelec is able to merge all the routing information into a single database – further reducing facility and maintenance costs.

Features

eNuM query interfaceThe ENUM Server, which uses a cluster architecture, supports the RFC 3761 interface for high-volume transaction capability that scales from 1 TPS to 30,000 TPS. Reliability is maintained within the cluster through redundancy and automatic recovery mechanisms.

Number portability corrected dataThe Tekelec private ENUM solution consists of a provisioning mechanism and an ENUM query/response server. The operator ENUM database is provisioned from a number of sources. These include both ported and non-ported telephone number data already provided via a number portability provisioning system. Operators using Tekelec’s Number Portability application, supported by the EAGLE 5 platform, can leverage this existing NP source to feed the ENUM database. Additionally, Tekelec provides a standard, web-based interface so carriers can provision their own data, if necessary.

database integrity and capacity The EAGLE XG ENUM Server is built on Tekelec’s proprietary database technology that ensures data integrity within the cluster of servers. Provisioning data is checked before distribution within the cluster to ensure that the database of 384M numbers can be properly maintained. The provisioning rates match the number portability provisioning rates while maintaining a full traffic load and collecting measurements.

provisioning interfacesThe ENUM Server leverages the Tekelec Local Service Management System (LSMS) interface for downloading number portability corrected subscriber data to one or more systems. This source can also be used to feed NP information to Tekelec’s ENUM Server. Additionally, Tekelec has worked closely with CableLabs, Verisign and other vendors, on an ENUM server provisioning protocol (ESPP) specification, which has been submitted to the IETF for consideration. The ESPP specification introduces a method for the synchronization and storage of critical service and routing addresses.

turnkey hardware platform solutionThe ENUM Server features the latest carrier-grade, server technology that is fully delivered, installed and supported by Tekelec. The underlying middleware and operating system are an integral part of many Tekelec solutions, which reduces the development and support cycles.

Alarms, debug, measurements and reporting The ENUM Server incorporates alarms via the management interface and simple network management protocol (SNMP) and a strong capability to debug query issues, collect real-time measurements, and generate reports to maintain the system.

Highly reliable and availableTekelec’s ENUM servers and blades are carrier-grade and provide 99.999 percent availability.

flexibility and scalabilityTekelec’s ENUM Server is deployed on high-performance servers that scale from 1 TPS to 30,000 TPS in a single system. The application scales in query and database capacity and supports multiple site deployments to provide reliability through geo-diversity.
