1. Are CTRL and PLC available in tunnels in November? CTRLs will be ready and no deployments are scheduled for end of October in tunnels. So they shall be available for testing new devices; 
2. XTD10 tunnel is closed due to the cabling installation: Cycling is not permitted and barriers shall not be removed. One still can go by foot and check if someone can pass through. 
The activity is planned to finish by end of next week. Please contact XO is work in XTD10 has to be done by other groups.
