We will intervene on the loop 2 for security works (same as what has been done on the Loop 1, see task # 5763). This involves a migration of DSLAMs uplinks to a new transportation equipment. So there will be a cut off for the service on each successive NRA,we will try to minimize it as much as we can.
We planned a maintenance window of 1 hour by NRA, knowing that the effective cut off should not take more than few minutes. Work will begin around 22:00. The NRAs will be impacted in the following order: HEL59, TRI59, ASQ59, LZI59, LQN59.
