Phase 5 Upgrade Completed!

I am pleased to announce that this morning, we successfully completed
the Phase 5 ANSNet deployment. The major changes accomplished in this
upgrade were:

   o Upgrade of all DS3/HSSI router serial interface adapters (T3
      CNSS and ENSS) to support full DS3 bandwidth. The router
      adapter bus interface cards were also upgraded to double the
      packet switching rates per interface.

   o The T3 DSUs on each DS3 interface were replaced with T3Plus
      BMX45 bandwidth managers on T3 CNSS-CNSS circuits and Larscom
      Access-T45 DSUs on a T3 ENSS-CNSS circuit.

   o The architecture for interconnection among CNSS routers at
      each MCI POP location was upgraded to a common FDDI ring from
      the original point-to-point links architecture.

As a result of this upgrade, we have 17 backbone links and 21 customer
attachments running at full T3:
  Seattle - Denver Backbone Link
  Seattle - San Francisco Backbone Link
  San Francisco - Chicago Backbone Link
  San Francisco - Los Angeles Backbone Link

     * New York - Wash DC Backbone Link
       Houston - St. Louis Backbone Link
       Denver - St. Louis Backbone Link
       St. Louis - Chicago Backbone Link
