Q&A


4/30


Explosive Growth

Smartphones aredriving data tablets,too

Video traffic is onlygoing to increasedemands


5/30


Its Complicated

Current backhaul based on PDH/TDM is tooexpensive

Ethernet is the affordable alternative easy to scalewithout major capital outlays

LTE introduces new requirements

You need to support existing and new services asyou move to packet backhaul


6/30


Opportunity Knocks

Mobile backhaul market revenues are expected toexceed $8 billion by 2015 (DellOro Group)

Cable MSO infrastructure well suited for backhaul

Win-Win Wireless operators need backhaul; cable

operators have it


7/30Building Better Backhaul

Discussion Topic

From a mobile backhaul

perspective, what arewholesalers doing to cope

with this explosion indemand?


8/30Building Better Backhaul

Wholesale Mobile Backhaul Activity

Leveraging existing network assets andinfrastructures that meet current requirements.

Accelerating network growth and upgrade plans for

current and planned Carrier Ethernet networkinvestments.

Testing & deploying new access nodes with Carrier

Ethernet OAM and converged service capabilities.

Building and extending fiber to a large number of cellsites.


9/30


Discussion Topic

What can operators do now to

prepare their backhaul networkfor new IP/Ethernet based

services?


10/30


Preparing your network for MobileBackhaul

All IP networks are not created equal: Providers with converged service networks today carrying voice and video are well

positioned to meet these new requirements. An Internet focused best effort IP network will require significant investments and

upgrades for wireless backhaul.

Network Design Review Review network design and performance criteria for element diversity, redundancy,

and convergence performance.

Service & Operations Impacts: New service classes required to meet service SLA & network performance

requirements. Implement Ethernet Performance Management & Reporting Capabilities. Operations assessment to meet aggressive MTTR, performance and reporting

requirements.

Technical Impacts: 1G & 10G client UNI and access capabilities. Support diversely routed fiber access topologies to MTSO with dual homing

capability. LAG support for 2-4 member links. Assess network synchronization needs. Mini jumbo support.

Discussion Topic

With LTE deployments

starting in the US, what must

wholesale providers do toensure they are in a good

position to capture backhaulrelated business?


22/30


Discussion Topic

How should operators address

OAM, synchronization, andscalability requirements?


23/30


Ethernet OAM

Ethernets popularity for aggregation and backhaulbrings a requirement to monitor the quality of theEthernet transport service

Transport OAM practices must be inherited to ensurehigh availability, performance monitoring and multi-domain support

Goal : bring OAM capabilitiesequivalent to SONET/SDH

Synchronization for Packet Networks

Mobile backhaul solutions must offer frequency and phase clocksynchronization to allow service providers to differentiate their service offering

Synchronizationrequirements:

Generally, 2G/3G networks

require frequency sync withexception of CDMA which

also needs phase sync

Now with LTE, twoapproaches:

FDD mode requiresfrequency only with someexceptions (e.g. eMBMS)

TDD mode requires bothfrequency and phasesynchronization
