It covers the aspects relating to functional architecture, the characteristics of monitoring equipment and the parameters for monitoring. 2016-01-01T00:00:00Z 10-Gigabit-capable symmetric passive optical network (XGS-PON) https://yse.yabesh.ir/std/handle/yse/251964 10-Gigabit-capable symmetric passive optical network (XGS-PON); ITU-T G.9807.1 (06/2016) ITU-T - International Telecommunication Union/ITU Telcommunication Sector Recommendation ITU-T G.9807.1 describes a 10-Gigabit-capable symmetric passive optical network (XGS-PON) system in an optical access network for residential, business, mobile backhaul and other applications. This system operates over a point-to-multipoint optical access infrastructure at the nominal data rate of 10 Gbit/s both in the downstream and upstream direction. Recommendation ITU-T G.XGS-PON contains the common definitions, acronyms, abbreviations, conventions, General requirements, Physical Media Dependent layer requirements, and Transmission Convergence layer requirements of the XGS-PON system. 2016-01-01T00:00:00Z ITU-T G.9701 (2014) Cor. 3 (04/2017) https://yse.yabesh.ir/std/handle/yse/251959 ITU-T G.9701 (2014) Cor. 3 (04/2017) ITU-T - International Telecommunication Union/ITU Telcommunication Sector Corrigendum 3 to Recommendation ITU-T G.9701 (2014) adds several clarifications, and fixes various errors and inconsistencies. 2017-01-01T00:00:00Z ITU-T G.9701 (2014) Amd. 3 (04/2017) https://yse.yabesh.ir/std/handle/yse/251958 ITU-T G.9701 (2014) Amd. 3 (04/2017) ITU-T - International Telecommunication Union/ITU Telcommunication Sector Amendment 3 to Recommendation ITU-T G.9701 (2014) supports the following new functionality: full specification of the 212 MHz profile, Annex X – Operation without multi-line coordination intended for a crosstalk free environment (e.g., coaxial cable medium) including dynamic time assignment (DTA), Annex T – higher layer control aspects of DTA, and Annex S – software download to NTs. 2017-01-01T00:00:00Z
