Alcatel 7270 MSC
Multiservice Concentrator | Release 6.0
The Alcatel 7270 Multiservice Concentrator (MSC) is a carrier class edge services switch that adapts, aggregates and implements services for ATM/IP/MPLS converged networks. Providing advanced traffic management on a standards­based platform, it enables the profitable delivery of differentiated services for managed IP/MPLS, video, ATM, frame relay and private line applications.
In addition to its service delivery role, the fully managed Alcatel 7270 MSC allows carriers to optimize their network infrastructure by provid­ing broadband aggregation for 2G/2.5G/3G mobile, fixed wireless and DSL traffic.
There are two variants of the Alcatel 7270 MSC, a 6-slot version suited for customer located applications, and an 8-slot variant suited for carrier infrastructure applications. All control, switching hub and interface cards are common to both the 6-slot and 8-slot Alcatel 7270 MSC.
Ensuring profitable service delivery with a scalable, flexible and reliable platform
