Markets

CLECs

Key competitors: ALU, Huawei, ZTE, Ericsson,

Zhone, ECI, Calix

Key Characteristics

•More sensitive to OPEX to drive competitive end-

user pricing

•Relationships are important, but not as unleveled

•Shorter cycles - quick adoption of new

technologies

Key competitors: ALU, Huawei, ZTE, Ericsson

Key Characteristics

•High revenue, big margin pressure with silos

•High touch with deep, long relationships

•Longer cycles and often unique requirements

•Complex OSS systems often precluding

converged business/residential networks

•Drive technology and cost curves


MSAN Dimensions of Competition

Higher Margin Services

Huawei and NSN are both very strong at delivering purpose-built, low-cost residential copper and

fiber services. The ADTRAN/NSN value is delivering a wider range of services, including business

Ethernet and service migration capabilities. We should focus on customers that value a platform

that delivers these higher-value capabilities.


Sales Strategy - Summary

Strengthen and expand Global Tier 1 relationships – Introduce differentiated, converged architecture concepts

– Secure long-term roadmap alignment

– Leverage for reference selling into other carriers/regions

Target non-Tier 1’s where timing plays to ADTRAN key differentiators and higher margin potential

Use market demographics to reinforce geo priorities

Expand global services and support to help offset competitive threat from large OEMs & to create higher business value relationships

Explore Ericsson and perhaps other non-BB oriented OEMs channel opportunities

Create coverage plan to insure key business strategy enabled – responsiveness, business solutions partner
