Alcatel-Lucent 7270 MSC User Manual
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
