Alcatel Carrier Internetworking Solutions 9500 MPR - Manual (Page 3)

The mobile market is changing, and to
remain competitive, mobile service
providers must deliver new profitable
services and reduce their backhaul
costs. Mobile user demand continues to
move beyond basic data services like
instant messaging and e-mail to more
delay sensitive applications like media
streaming and real-time multimedia. In
response, broadband wireless
technologies including high-speed
packet access (HSxPA) and evolution data optimized (EV-DO) are evolving to
enable higher transmission speeds and
packet interfaces. Backhaul networks
must evolve to meet these new
bandwidth demands at acceptable cost
points.
IP transport can help mobile providers
transform their networks — to better
manage the increasing traffic demands
of broadband services. To satisfy the
need for new packet backhaul solutions,
Alcatel-Lucent offers a revolutionary
way of transporting packets natively.
With this new approach, the Alcatel-
Lucent 9500 MPR product can assure
the quality of service required for each
traffic type, dramatically reduce OPEX
and improve the connectivity of
Ethernet and legacy E1 base stations.
As a result, your network can absorb
rapid growth in multimedia traffic easily
and efficiently, with a smooth migration
from TDM to IP.

Figure 1. TDM Transport compared to Packet Aggregation. There is a clear gain in scarce radio resources when transporting packet traffic natively.
Packet solutions can absorb TDM traffic efficiently while TDM solutions cannot handle packet traffic cost-efficiently.
