Alcatel-Lucent 7510 Media Gateway
The high-capacity Alcatel-Lucent 7510 Media Gateway (MGW) builds a service-aware edge for voice, fax and data in user-centric broadband networks by providing any-to-any media switching and interworking for circuit and IP ports. As a member of the Alcatel-Lucent 7500-series of multiservice MGWs, it allows flexible rollout of PSTN migration and new IP services in both the metro-transit and the local-access layers of the Alcatel-Lucent IP Multimedia Subsystem (IMS) solutions as well as any multivendor next-generation network.
Multiservice media networking
The Alcatel-Lucent 7510 MGW builds high business value based on multiservice flexibility across six dimensions:
•Multiple services: supports end-user services ranging from toll-quality voice to multimedia streams
•Multiple solutions: provides a single platform for hosting key medianetworking solutions ranging from plain TDM switching over Voice over IP (VoIP) trunking, digital loop carrier (DLC) and Private Branch Exchange (PBX) access to session border peering and Signaling Gateway (SGW) applications
•Multiple sizes: allows seamless scaling of production services across a wide capacity range without compromising essential attributes such as cost per channel, resilience and interface feature compatibility
•Multiple standards: offers an IMS-compliant interface to the service-delivery platform based on the leading protocol standards, Megaco/H.248 and Signaling Transport (SIGTRAN)
•Multiple softswitches: provides interworking that is also proven with non-Alcatel-Lucent softswitches
•Multiple switching options: maintains Quality of Service (QoS) by switching the media natively, through IP or TDM, without excess transcoding stages
As shown in Figure 1, the Alcatel-Lucent 7510 MGW is the cornerstone of any user-centric broadband network.

Key benefits |
|
|
|
•Multiservice: converged platform capable of hosting VoIP trunking, access and session-border applications concurrently; integrates key IMS functions such as IMS media gateway (IMS-MGW), trunking media gateway function (T-MGF), Interconnect Border Gateway Function (IBGF), Centralized Access Border Gateway Function (C-BGF) and SGW
•High scalability: allows flexible use of generic slots for pooled media resource and interface cards
•Multivendor networking: complies with the IMS profiles for signaling and control protocols, Megaco/H.248 and SIGTRAN
•Carrier grade: provides toll-quality voice services with highest availability (100-percent hitless redundancy)
•High asset productivity
¬Delivers critical end-user services with high quality
¬Provides guaranteed non-stop services
•Lowest cost of ownership
¬Seamless scalability ensures efficient capacity expansions up to highest port densities
¬Multiservice platform generates economy-of-scale savings and safeguards investment while evolving to a converged end- to-end all-IP architecture
