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-slotversion suited for customer located applications, and an8-slotvariant suited for carrier infrastructure applications. All control, switching hub and interface cards are common to both the6-slotand8-slotAlcatel 7270 MSC.

Ensuring profitable service delivery with a scalable, flexible and reliable platform
