Hatteras Networks Extends its Ethernet-over-Copper for Mobile Backhaul

Hatteras Networks unveiled a new modular, multi-service platform designed to enable carriers to offer business Ethernet services and mobile backhaul solutions using their existing copper infrastructure.
The rollout includes a new central office platform, pseudowire capabilities that can be extended to base stations, and a low-cost CPE device that can bond eight T1/E1 signals over a single Ethernet connection.


The new 40 Gbps HN6100 is a two-rack-unit Ethernet switching platform that delivers Ethernet-over-Copper, Ethernet-over-TDM and Hatteras' PWE3-plus (native TDM & Ethernet for Mobile Backhaul). Line card options include 16 port EFM, 16 port T1/E1, 3 port DS3 (Clear & Channelized). For EFM, the HN6100 is capable of 32-pair bonding, which could deliver up to a 480 Mbps pipe (15 Mbps per pair X 32 pair bonding). The same HN6100 multi-service chassis will also support Ethernet over Fiber in the future. The HN6100 is suitable for deployment in a central office, controlled environmental vault or outside plant remote-terminal, and it can be deployed at a cell site or customer location, as well. The HN6100 is now commercially available.


The product rollout includes a new HN600 Series CPE device, which can be terminated at the central office with the HN6100. Significantly, the HN600 Series features support for PWE3-plus, Hatteras Networks' patented method of simultaneously transporting native Ethernet and native TDM with embedded network timing over the existing copper infrastructure for mobile backhaul. PWE3-plus natively transports Ethernet and TDM traffic with full network timing while running across existing copper pairs. Traffic is spread across all pairs at the bit level. Hatteras calculates that the HN600 delivers 10 times more bandwidth at one-tenth the cost of existing mobile backhaul solutions.


Hatteras Networks said that unlike traditional PWE3, which suffers from the delay, jitter and timing impacts of packetization, its PWE3-plus perfectly emulates a T1 and precisely passes timing synchronization information. Furthermore, with the Hatteras Networks mobile backhaul solution, carriers simply "Turn-the-Dial" to adjust to any mix of TDM and Ethernet services, to be simultaneously transported unaltered in their native format. In the case of voice services, PWE3-plus spreads and prioritizes voice timeslots across bonded copper pairs, dynamically reassigning remaining bandwidth to augment allocated data-traffic capacity. Ethernet traffic never interferes with TDM traffic. The HN600 Series with PWE3-plus is available today.


"Existing backhaul technologies have hindered the profitability of carriers around the world despite the phenomenal growth in demand for mobile broadband services. Our new HN600 Series with PWE3-plus transforms the equation, enabling mobile network operators to cost-effectively scale and harvest significant new revenues from existing infrastructure," said Kevin Sheehan, CEO of Hatteras Networks. "We have engineered an innovative, purpose-built mobile backhaul solution that conveys the best of both Ethernet and TDM transport and delivers resilient, low-latency, scalable access to the mobile wireless tower today and moving forward."


Hatteras Networks also introduced its HN500 Series compact customer premise equipment (CPE) for enabling Ethernet over Time Division Multiplexing (TDM) and Ethernet over NxT1/E1 services. The carrier-class HN500 Series can bond up to eight T1/E1 signals over a single Ethernet connection and provide services of up to 12 and 16 Mbps respectively.


The HN500 Series connects to Hatteras Networks' new HN6100 at the carrier central office to extend Ethernet business services to any location served by copper. The plug-and-play demarcation device features Hatteras' "zero-touch" technology, providing standards-based operations, administration and maintenance (OAM) and carrier-class reliability and troubleshooting. It can be automatically and remotely updated, configured and monitored, reducing a carrier's number of truck rolls. Support for flexible virtual local area network (VLAN) manipulation, traffic shaping, traffic policing and hierarchical traffic management allows a carrier to ensure delivery of multiple services competing for limited access bandwidth.
