Alcatel-Lucent 9500 Microwave Packet Radio2

The Alcatel-Lucent 9500 Microwave Packet Radio (MPR) provides cost-effective IP transformation for

seamless microwave transport of TDM, ATM, IP and Ethernet traffic over a Carrier Ethernet infrastructure.

The steady increase of data services in backhaul networks results in high capacity and costs if addressed

with traditional TDM or hybrid microwave systems. The Alcatel-Lucent 9500 Microwave Packet Radio (MPR)

packet-based platform is a multiservice aggregation platform that uses Circuit Emulation Service (CES) (MEF 8)

and Pseudowire (PWE3) to seamlessly transport TDM and ATM with no radio-performance degradation,

providing a Carrier Ethernet microwave-transport infrastructure and introducing the required flexibility

to carry more capacity with lower costs.

It is recognized that circuit-based transport will still be used for some time, and the transition to

packet-based transport cannot happen overnight. To solve this issue, the Alcatel-Lucent 9500 MPR

operates as a hybrid microwave fully interworking with the existing installed base with comparable

performance, while enabling IP transformation at the pace of the network with the same hardware.

The operator is now free to maintain its current mode of operation using a TDM/hybrid model and to

start migrating to packet as data traffic grows, boosted by IP-3G nodeBs and HSPA where needed.

FEATURE BENEFIT

The Multiservice Aggregation-Layer feature aggregates and carries TDM 2G, ATM 3G and IP/Ethernet over a common packet layer. This allows sharing of a common packet-transmission infrastructure, regardless of the nature of the traffic carried. Mapping of different access technologies over Ethernet is achieved with standardized protocols.

A single transmission pipe is used for all services and access technologies on cell sites. Radio bandwidth is utilized at 100 percent.

In contrast, TDM radio stacks multiple data streams (E1, Ethernet) over the radio channel and underutilizes a large portion of the bandwidth. Moreover, hybrid platforms do not provide circuit emulation or ATM pseudowire.

With the Service-Awareness feature, different services are treated according to their QoS requirements.

Operators achieve end-user satisfaction even while using services other than voice, using the minimum necessary bandwidth.

In contrast, with TDM products there is no possibility of differentiating services: all are treated as top-priority, with no differentiation between voice and best-effort broadband.

The Alcatel-Lucent 9500 MPR operates as hybrid or packet-node on a single packet matrix with high switching capacity (greater than 16 Gb/s).

The Alcatel-Lucent 9500 MPR can switch, aggregate and handle many incoming traffic types with almost no capacity limits (greater than 16 Gb/s) and without additional external switches. In addition, the Alcatel-Lucent 9500 MPR is able to deliver synchronization in packet networks using SyncE, E1 or sync-out ports.

The Service-Driven Adaptive Modulation feature allows full exploitation of the entire air bandwidth by changing modulation schemes according to propagation conditions and by associating different service qualities to the available transport capacity.

Scarce spectrum resources are used efficiently in all conditions and at a lower cost than renting.

High-priority traffic is transported in all conditions with no degradation in perfor-mance, thanks to a “hitless” modulation switch.
