Huawei completes DSL retransmission IOP test

To accommodate the rapid demand for video broadband services, broadband carriers seek to provide high-speed and high-quality data and IPTV services through existing DSL resources.

The key to delivering stable DSL lines is reducing impulse noise interference. ITU-T G.998.4 retransmission technology is an important milestone for DSL technology because it improves DSL stability by diminishing impulse noise, lowering high bit error rates (BER), and reducing the number of dropped VoIP calls, and frozen, blank, or paused screens.

“Broadcom is pleased to have reached interoperability of retransmission and to have contributed essential elements to ITU standardization of this technology. We have demonstrated the outstanding performance advantages of this technique for several years, and now, by working with our partners, we believe re-transmission will become an essential part of IPTV deployments worldwide,” said Greg Fischer, vice president and general manager of carrier access for Broadcom Corporation.
