With the patented Hatteras Networks Pseudowire-Plus (PWE3-Plus) technology for mobile backhaul solutions, 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.
Consequently, the call quality delivered via a native TDM service transported between the HN6100 and HN600 Series is indistinguishable from services transported via traditional T1/E1. All of the flexible bandwidth scaling and cost advantages of Ethernet can be realized in copper-based mobile backhaul without compromising the timing and voice-quality benefits of traditional T1/E1. PWE3-Plus supports any of the critical TDM service parameters (wander, jitter, latency or synchronization, for example) and at the same time any state-of-the-art Ethernet service. In this way, coupled with the HN6100 and/or the HN600 Series this allows migration to 3G and 4G base stations over time, even where the connections to cell towers are copper; mobile backhaul networks can be transitioned gradually and seamlessly from TDM to Ethernet.

Big Increase in Bandwidth and Reliability
- Increase bandwidth with 2BASE-TL for both Ethernet and TDM traffic
- TDM has a flexible reserved amount of throughput over bonded connection
- TDM automatically adjusts to pair rates and failures
- Timing redundantly carried at physical layer
Benefits:
- Meets all requirements of any existing TDM tariff
- More capacity (multiple T1s or E1s on a single line)
- TDM is never delayed by Ethernet packets
- Carrier has FLEXIBLE bandwidth for TDM and data
Operational:
- Physical lines are partitioned into logical TDM and Ethernet paths
- TDM has a reserved amount of throughput over bonded connection
- TDM automatically adjusts to pair rates and failures
- Timing redundantly carried at physical layer
Benefits:
- Meets all requirements of any existing TDM tariff
- More capacity (multiple T1s or E1s on a single line)
- Better reliability than existing T1/E1
- TDM is never delayed by Ethernet packets
- TDM is not packetized and CRC’d
