Alcatel-Lucent 7705 Service Aggregation Router 5

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.

Note: The 7670 RSP supports ATM and Ethernet pseudowires. The 7710/ 7750 SR also supports ATM and Ethernet pseudowires, support for TDM pseudowires will be added in R 6.0.
