Dear Customer, 
Thank you for your confidence in the AT&T Managed Broadband Service. This access technique provides you with high-
speed connection to your Corporate Network and the Internet. 
AT&T delivers Managed Broadband service in close cooperation with a central person / support group within your 
company (Customer Point of Contact or CPOC). This group would distribute the Do-It-Yourself package and is also 
responsible for a correct set up of your network settings. To ensure a controlled flow of information and equipment, 
the support group will be the interface between you as end-user and AT&T. 
At this moment, we are in the progress of enabling your DSL line(s). As soon as the line is ready, we will inform the 
support group within your company, so you can commence with the installation of the modem and start using the 
service. 
Now you have received the Do-It-Yourself installation package. So following the installation guidelines included in this 
package, you can install the xDSL modem. The modem is pre-configured; so minimal configuration is required. If you 
applied for AT&T assisted installation, the installation will be done for you at the agreed date. 
Please note that 10 working days after we have enabled your DSL connection, we will begin to charge your company 
the agreed monthly DSL connectivity fee and monthly service charge. We recommend you read through the 
installation guideline within this period. In case the DSL installation does not function to your satisfaction, please 
contact your support group within the 10 working days so we are able to postpone the moment of billing. 
AT&T is fully dedicated to ensuring high performance of your DSL connection. In case you experience problems or you 
have any questions, our Support Center is fully dedicated to provide you with support. Please, address your question 
to the support group within your company, after which they can call our Support Center. In order to offer the best 
assistance, please make sure your support group has your Account and User ID nearby. 
Yours sincerely, 
 
AT&T Enablement Team
