NERO will be performing a number of upgrades on the NERO Backbone
Optical Transport system to implement a number of upgrades.  When this
work is completed the new Backbone Optical Transport system will be
fiber path and node diverse between the Eugene, Corvallis, Pittock and
Salem Hubs.  This will also upgrade all links to full Gigabit Ethernet
interconnects and provide for additional expansion when it becomes

This work is not expected to impact operational traffic and will be
staged so that at least one existing operational redundant path will
always be available in the case of problems on individual links.

Next Tuesday morning, December 20, 2005, 0400-0600, the Eugene to
Corvallis and Corvallis to Pittock backbone interconnects will be moved
onto the new system.  Existing traffic will be moved onto alternate
links before the transition and moved back after the new links are up
and operational.

The following Tuesday morning, December 27, 2005, 0400-0600 we will be
performing fiber splice work on the protection fibers between the
Pittock, Salem and Eugene Hubs on the existing SONET transport system.
This work will also be transparent to existing traffic as the SONET
protection paths will activate automatically with no traffic

The final work will be performed on Wednesday morning, December 28,
2005, 0400-0600 to move the backbone interconnects between Pittock and
Salem, and Salem to Eugene onto the new system.  Once again, traffic
will be moved onto alternate links while the new links are brought
online and tested and then traffic will be returned to normal.
