The Business Case for Packet Based Aggregation/Transport
Aggregation is the “core” of the RAN backhaul 3G Traffic is exploding Greater traffic optimization by statistical multiplexing at
aggregation points Multiservice Packet based backhaul allows for
> Decouple bandwidth from transport cost> Flexibility and protection investment in migrating from TDM
to packet> Flexible bandwidth upgrades> Granular QoS control for converged multiservice traffic
The role of aggregation in an all Ethernet network> Network hierarchy for flexible last mile and backhaul
solutions> Enable end to end Ethernet transport by preserving QoS
and traffic management capabilities across the network
The key to lowering the cost per bit of carrying data through the mobile network is the adoption of packet technology in the backhaul

Step 2 – Network Synchronization (adaptive timing)
Applicable for TDM pseudo wires > TDM interface (E1/T1) synchronized based on the
arrival frequency of the TDM emulation packets Monitoring of the arrival times of the packets with
minimum delay> Does not require the use of the RTP/UDP/IP protocol
overheads and timestamps Adaptive clock recovery algorithm runs in NPU
(Network Processing Unit)> Compensate for occasional packet losses and/or
reordering Tested to be compliant with the G.823/G.824 jitter
and wander specifications under PSN packet delay variation of up to 10ms

What Analysts Say about IM Solution?
“Tellabs has taken RAN optimization to the next level by providing a solution that ranges from the cell tower to the mobile IP core. The addition of the 8605 access switch will further reduce the backhaul complexity and costs by converting the multiple generations of wireless traffic to Ethernet directly at the cell tower.” – Current Analysis, February 2007

Telecom Italia’s view on the project
“Telecom Italia’s convergence strategy is driving extensive network and support cost savings in both its fixed and mobile units. A significant element of this strategy involves incorporating Tellabs solutions to collapse traffic from its UMTS/HSDPA mobile network, which transmits over Asynchronous Transfer Mode (ATM), onto Telecom Italia’s existing Ethernet backbone that is already being used for fixed broadband services. That means we can save a substantial amount on backhaul costs in the HSDPA development.”
