NBASE-T Downshift is a protocol specified in the NBASE-T physical layer specification 2.3, which adds functionality to NBASE-T, IEEE 802.3bz and other IEEE 802.3 BASE-T technologies using the proven mechanisms in Ethernet Auto-Negotiation.
NBASE-T Downshift: Optimization of 2.5Gb/s and 5Gb/s Ethernet Data Rates Over Cat5e/Cat6 Cabling. This white paper describes NBASE-T Downshift and how it optimizes transmission rates to get the highest achievable data rate out of installed Category 5e and Category 6 structured cabling. NBASE-T Downshift augments the IEEE 802.3Bz™ standard by …
With NBASE-T Downshift, the best available data rate is selected for the connected link. Downshift works for 10Gb/s and other rates in addition to 2.5Gb/s and 5Gb/s. Downshift enables a link that fails to automatically renegotiate (with no manual re-configuration required via a management interface) to a lower link speed using the IEEE 802.3bz standard Auto-Negotiation mechanism.
– NBASE?T Downshift adapts to cabling to achieve the best performance • NBASE?T supports use cases (including 802.11ac Wave 2) at > 1Gbps • Cabling standards and guidelines for NBASE?T/802.3bz on the way • Field test procedures to maximize performance are available, With NBASE-T Downshift, you can optimize your transmission rate to get the highest achievable data rate out of installed Category 5e and Category 6 structured cabling. NBASE-T Downshift augments the IEEE 802.3bz™ standard by providing a mechanism to select the best speed available within the constraints of the cabling. Download Here.
6/14/2017 · Before NBASE-T Downshift, a 10GBASE-T link would quickly drop down to 1000BASE-T or drop the link all together. Low Latency; This demo showed the consumer applications, in which a movie was being played over the network. A Blu-Ray player was connected to a TV through two NBASE-T switches and displayed no latency, opening up applications for an …

10/6/2017 · NBASE-T uses a technique to downshift the signaling rate used in 10 GbE to either one-quarter (2.5 Gbps) or one-half (5 Gbps) the rate. This modification allows existing copper cabling to handle the higher speeds.
The use of NBASE-T interfaces will allow updating the existing wired network segments with the minimum expenses and to be prepared for the deployment of the next generation IEEE 802.11AC Wave 2 wireless networks. NBASE-T usage allows increasing significantly the performance of the wired segments without a cable infrastructure replacement.
