FS#2017 — FS#5992 — Lille loop 3 (SAN59,WAS59, RON59, TOU59, RSA59, STM59) - 25/10/11

Attached to Project— ADSL / SDSL
Maintenance
Backend / Core
CLOSED
100%
We will intervene on the loop 3 for the security works(same as what has been done on the Loop 1 and 2, see task # 5763 and task # 5909).
This involves moving DSLAMs uplinks to a new transportation equipment. So there will be a service cut off on each successive NRA that we will try to minimize as much as we can.
We planned a maintenance window of 1 hour by NRA. Works will begin around 22:00.
The NRAs will be impacted in the following order: SAN59, WAS59, RON59, RSA59, STM59.

We will work tonight on the NRAs: SAN59, WAS59 and RON59.
Date:  Saturday, 29 October 2011, 08:09AM
Reason for closing:  Done

We had too much attenuation between RON and SAN,which prevents us to setup the link under normal conditions. We postponed RON59 failover to the next maintenance on Thursday.

We have met difficulties in TOU59. The port of one transport equipment was defective in Roubaix. We have moved the link to another port. The DSLAM is back online. We attack the RSA switch.
