Ethernet over Copper Service Delivery

A Case Study on C&W Barbados

July | 2008

Carrier Ethernet over Copper™


Introduction

C&W Barbados long viewed as leader in advanced telecom servicesLocal telephone services established in only 9 years after the Alexander Graham Bell’s first exhibited the telephoneDeploying undersea cables as early as 1872 making it the West Indies “convergence point”Established a wireless telegraph station in 1914Initial Caribbean satellite deployments in 1972Initial Caribbean fiber optic deployments in 1982

C&W Barbados services have typically been in lock step with other leading countries

C & W Barbados mission: deliver full suite of products and services for its sophisticated customers

TelephonyBroadband InternetMobile Voice & DataBusiness Solutions


Challenge Begets Opportunity

C&W is the dominate service provider in Barbados todayCompetition has been increasing from emerging broadband providersC&W was heavily reliant on legacy circuits

Fiber was used when availableTDM (E1) circuits used for the many customers out of fiber’s reachE1’s provide limited bandwidth at 1Meg per pair and existing TDM network had become overburdened from current demandATM bonding (i.e. IMA) is extremely inefficient

C&W needed an immediate network upgradeTime to market was critical to success!

Dilemma: How can C&W Barbados migrate from legacy E1 circuits to a next generation and future-proof network …

Without breaking the bank?


Driving the Customer Demand

Business are requiring higher bandwidth for new packet applications:

VoiceDisaster RecoveryMulti-mediaWeb Collaboration

Connecting more locationsMore customersMore branches of existing customersReaching all parts of the island, regardless of distance, is essential

Packet networks are now carrying mission critical applicationsHighly reliable service is a must!Application assurance must afford SLA guarantees

Ethernet has become the defacto standard


Simplicity:Ethernet has become a nearly ubiquitous and well understood technologyEthernet is the dominant LAN protocol offering native LAN to LAN connectivityEthernet is more efficient with less overhead

Scalability:Speeds available from less than a megabit to many gigabits & software bandwidth provisioning eases upgradesFlexible provisioning supports virtually all applicationsQoS models guarantees application reliability

Value:Simpler networks lead to less equipmentWide scale deployments leads to lower equipment costsUbiquity leads to lower operational costs

Metro Ethernet Network

Why Carrier Ethernet?


So … How Do We Meet the Demand for Ethernet?

Strategy for delivering Ethernet to all businesses across the island:Use fiber when it is available and cost effectiveUse existing copper when fiber is not available and trenching for new fiber is not an option

But … Is copper a viable alternative?

Can it deliver the required bandwidth?Can it serve all of the required customers and their locations?Will it meet the customer Service Level Agreements?Can it integrate into the existing fiber based Ethernet network?


Business Case Behind Ethernet over Copper

Feasibility Test:Reach with Copper? Is fiber infinite?

Bandwidth required for today and tomorrow? Is fiber infinite

Fiber-like reliability? Is fiber unsurpassed?

Spectral Friendliness - Impact on other Services?

The cost to deploy?The cost to maintain?Growth and Scalability capabilities? SLAs - Level of QoS support

ROI - Worth the cost?

The Challenge: Cost effective delivery of Ethernet over copper, while maintaining

fiber’s perceived service quality?
