. ▫ Connecting the broadcasting device via an Ethernet cable ensures maximum stability. ▫ In the absence of a cabled connection, the Wi-Fi signal must be excellent. ▫ Log in early to test the connection. ▫ Please use high quality microphones: ◦ lapel microphone; or ◦ unidirectional table microphone; or ◦ wired headset with a built-in microphone. ▫ Ensure that the broadcasting platform recognizes the microphone. ▫ Speaking from a quiet environment is of utmost importance. ▫ Avoid sitting in a large empty room to minimize echo. ▫ Avoid using the computer’s built-in microphone. ▫ Omnidirectional microphones pick up ambient noise and should be avoided. ▫ Avoid smartphone-style earbuds/earphones with in-line microphones and other Bluetooth devices.

  SG15 Last Meeting Executive Summary

Q8/15 worked on optical fibre submarine cable systems and agreed revised G. Suppl.41, which contains design guidelines for optical fibre submarine cable systems adopted for high bit-rate coherent systems. (...) It also made progress on DCN (G.7712) and management of OTN (G.874, G.874.1), Transport Ethernet (G.8052, G.8052.1), MPLS-TP (G.8151, G.8152), Synchronization (G.sync-mgmt), and Media (G.media-mgmt). It started a new work item on G.8052.2 " Resilience Information & Data models for Transport Ethernet ". Q14/15 plans to hold two interim meetings in May and August in 2018.

  ITU-T Workshop on NGN and its Transport Networks

In order to realize "carrier class" Ethernet, ITU-T SG13 developed Recommendation Y.1731 on Ethernet OAM mechanisms with close collaboration with IEEE 802.1ag. (...) In order to enhance reliability of the Ethernet, ITU-T SG15 developed Recommendation G.8031 on Ethernet protection switching. (...) What are the strengths and weaknesses of Ethernet? This talk examines these issues and describes possible ways in which Ethernet may evolve to provide Next Generation Ethernet solutions.
