The Alcatel-Lucent 7549 Media Gateway (MGW) forms an integral part of the Alcatel-Lucent Mobile NGN Solution, delivering a dramatically simplified architecture as well as seamlessly evolving to an IP Multimedia Subsystem (IMS). A high-density, multiservice media gateway with voice and data-bearer interfaces, including TDM, IP and ATM, the Alcatel-Lucent 7549 MGW is capable of performing any-to-any switching, including native TDM-to-TDM, native packet-to-packet and TDM-to-packet.

Features

•Purpose-built, high-capacity, multi­ fabric media gateway for mobile service providers

•Innovative generation of gateway tech- nology with integrated media server, integrated signaling gateway (iSGW) and 3GPP† InterWorking Function (iIWF)

•M3UA-based iSGW card performs reliable SS7-to-IP interworking SIG- TRAN as well as limited SS7-to-SS7 functionality STP

•Support for multiple interfaces with ATM, TDM and IP

•Extensive set of GSM/UMTS and IMS features, CODECs and interfaces, in- cluding IPBCP, DTMF, congerencing, tones, annoucements, FRO and TrFO, and VQEs

•Integrated Wireless Element Manager (WEM) in the Alcatel-Lucent 5060 Wireless Call Server (WCS) manages both the Alcatel-Lucent 5060 WCS and Alcatel-Lucent 7549 MGW

•Highly reliable MGW based on field- proven software

†Available Q3 2009

Benefits
