9500 family overview
58 MPR-e and MSS-1c User Manual 3DB19901EFAA Edition 01
The 9500 MPR innovative solutions include:
• Multiservice aggregation layer: the capacity to use Ethernet as a common
transmission layer to transport any kind of traffic, independent of the type of
interface. Ethernet becomes the convergence layer.
• Service awareness: traffic handling and quality management, queuing traffic
according to the type of service assigned, independent of the type of interface
• Packet node: no service aggregation limits with all traffic aggregated in packets
according to: capacity, type of service requirements and type of interface
• Service-driven adaptive modulation: fully exploits the air bandwidth in its entirety
by changing the modulation scheme according to the propagation availability and
allocates transport capacity, discriminating traffic by different services, which is only
possible in a packet-based environment.
Multiservice aggregation layer
Figure 3.2 — Multiservice aggregation layer
The 9500 MPR aggregates and carries over a COMMON PACKET LAYER: TDM 2G,
3G, LTE and IP/Ethernet. This allows sharing of common packet transmission
infrastructures, regardless of the nature of the traffic being carried.
Due to the nature of Ethernet, each service can be discriminated based on several
parameters like quality of service.
Mapping different access technologies over Ethernet is achieved by standardized protocols
like circuit emulation and pseudowire.
