IP/MPLS RAN Transport
7705 SAR – 8-Slot Version
A complete Alcatel-Lucent IP/MPLS RAN transport capability can be built around the Alcatel-Lucent IP/MPLS portfolio (see Figure 1). Each product has undergone rigorous testing to ensure that the network you build provides you with unparalleled reliability, so your service offerings stand out in this highly competitive market. In order to provide the most efficient transport solution, the 7705 SAR employs pseudowire (PWE3) encapsulation methods to map services end to end. The use of pseudowires ensures that the key attributes of the transported service are maintained, while a cost-effective packet environment is used to perform aggregation.
