ADC Assists AT&T with
Facility Restructuring
Customer
AT&T is among the premier voice and data communications companies in the world, serving
business, consumer, and government customers. It runs one of the most sophisticated
communications networks in the United States, and is a leading supplier of data, Internet and
managed services for the public and private sectors. The company is a market leader in local, long
distance and Internet services, as well as transaction-based services like prepaid cards, collect
calling and directory assistance. AT&T has about 50 million residential and 4 million business
customers depending on their network for high-quality communications.
Requirements
AT&T Long Distance was transferring space on the 9
th
floor of their Denver Main central office in
Colorado over to AT&T Wireless and needed assistance with the transition. This area of the office
housed a large amount of equipment as well as cable racking and infrastructure. In addition to
removal of this equipment, AT&T also needed help with their overcrowded cable racks which were
limiting access to the rest of the network equipment. This included ‘mining’ various types of cable
down to the 7
th
floor so they could be disconnected from the far end equipment. All work
needed to be completed within a short, 2-week timeframe.
ADC Solution
With extensive experience in equipment removals and cable mining, AT&T looked to ADC’s
Systems Integration team to assist them with this facility transition. Soon after the initial site
survey, the ADC team in Colorado had moved into action. Upon approval of the SMOP (Service
Method of Procedure), work began on disconnecting and removing equipment for secure
packaging and shipment and ultimate reuse in another AT&T location.
Upon completion of the project, the following equipment and cabling were safely removed from
the facility:
• 2 BPX switches
• 6 Access shelves
• 1 DCN cabinet
• Other complementary pieces of equipment
• A total of 33.5 miles of cabling, including:
- 633 switchboard cables
- 16 power cables
- 2 fiber cables
Working long days, the ADC team had the entire 9
th
floor ready for AT&T Wireless to move into
in just 3 days – far within the original 2 week deadline.

Benefits Realized by the Customer
AT&T Long Distance was able to capture significant cost savings by having the equipment removed safely
from the area within the specified time period, avoiding facility transition penalties. “ I’ve never seen a
more coordinated effort and would find it hard to believe that another crew could have accomplished what
ADC was able to do in the time we gave them”, commented Chuck Kirgan, AT&T OSWF for the Denver
Main office.
Additionally, completing the removal work ahead of schedule ensured that the new infrastructure build for
AT&T Wireless was not delayed. Their new switch build began on time, ultimately driving new revenue-
generating traffic for AT&T Wireless. The entire project was completed on time and without the slightest
interruption in service.
With an intimate knowledge of the AT&T network and facilities, ADC continues to work closely with the
AT&T team in the Denver office as well as across the United States and Europe, providing valuable product
and service solutions.
