Revenue and OpEx were once linear.
Voice and text messages drove majority of current revenue as well as majority of backhaul impact.
All you can Eat Pricing Models drives demand to lower cost per bit delivered to user
Revenue per bit delivered is driven to lowest levels.
Significantly expand data capacity to enable new devices, services and applications  ARPU growth
LTE is 1st generation wireless network built as a data network
All-you-can-eat Pricing
Lots of ‘fat’ users
Reliance on TDM leasing
Copper dominance
1-2 E1/T1  4-6E1/T1  E1/T1
DS3 popular, sustainable?

32. Introducing Modular Ethernet Access Delivering the New T1 (and E1)
Complete Vision of Single Operational Model
Single Service and Maintenance Launch Point
Single, Versatile, High Value Ethernet Access Gateway for every access medium
One of the industry’s most versatile solutions, the NetVanta 8044M allows service providers to minimize the operational churn required to transition from legacy to next-generation services, access and network synchronization methods as the demand for mobile broadband networks drive the transformation to IP and Ethernet with the deployment of new technologies, such as Long-term Evolution (LTE). At the cell site, the ADTRAN NetVanta 8044M, delivers intelligent Ethernet services. The comprehensive solution delivers QoS-based Ethernet services while supporting transition from legacy TDM service via pseudowire standards as well as delivering a robust clock recovery mechanism over packet-based access. Modularity makes this solution unique, allowing it to be the only device on the market today that can enable carriers to terminate copper, fiber and bonded TDM services economically from a single platform.
The ADTRAN NetVanta 8044M Ethernet Access Device meets virtually every need of a multi-access, next-generation, mobile backhaul network. The NetVanta 8044M works in concert with the Total Access to allow an operator to universally aggregate and deliver Ethernet and TDM services over a plethora of access methods. The key value on the solution is the common operational model that greatly simplifies the deployment and migration of Ethernet services delivery over various interim access methods. Operators reduce the time to market for LTE services by leveraging the gamut of Ethernet access technologies: Ethernet over Fiber (GPON, Point to Point and Ring-based Ethernet) bonded copper access using e.SHDSL and VDSL2/ADSL2+ technologies as well as Ethernet delivery over bonded circuit access using both EFM and GFP-based TDM and SONET/SDH interfaces.
