 Experience
AT&T provided me with an excellent background in software engineering and the Software Development Life Cycle (SDLC). While at AT&T, I worked with some of the best programmers, software and network engineers. The company's deep roots in Unix and C definitely showed and a majority of the software we deployed was developed in house (e.g., our inter-process communication software (NIPC) was entirely written in-house).
The training and work at AT&T was great. I really enjoyed what I did and really loved the entire learning process. The work was challenging.
An area I felt that was lacking (at AT&T) was that our group had very little exposure to the "business" aspects of our service. We were software developers and worked mostly with engineering in designing and developing the Software Defined Network (SDN) system. I wanted to learn more about the "business" (not technical) aspect of telecommunications, the industry dynamics, the clients, etc.
Toward the end of 1999, the rise of the Internet cultivated my desire to learn "newer" web skills as well as quench my appetite for business knowledge. At the end of 1999 I decided to leave AT&T and start my own company called myRebates.com

My tenure at AT&T was in the Network Services organization. The group I worked in was responsible for the software development efforts of AT&T's Software Defined Network / Service Management System (SDN/SMS).
SDN provides large corporations with their own Virtual Private Network for voice and data. SMS provides AT&T customers with a high availability (24x7) system to control their voice/data telecommunications network. SDN/SMS enables authorized users to monitor and change SDN features to suit their particular communications needs. The development environment for SDN/SMS is client server using the HP-UX operating system, Oracle databases, and Pro*C (with embedded SQL) as the primary language.
As a feature lead on various SDN/SMS releases as well as the groups Configuration Manager, I was involved in all aspects of a system release (we used to have one release per quarter and one out of the four was infrastructure related, e.g., Oracle upgrade, etc.)
One particular area I was responsible for was handling area code splits; we called this NPA Splits. Splitting an area code seems simple, but the truth is that some of our most complex code and processes involved the splitting of NPA's (area codes). The challenge was rooted in the requirement to "provision" two area codes at the same time while numbers where being added, modified and deleted. For example, when a new number was issued (in the new area code), a "reverse split" had to happen in order to ensure that a call could be completed to either area code. For a sample of the scenario's involving an NPA Split, see this document provided by NeuStar, Inc's Number Portability Administration Center (NPAC). What added to this challenge of dual provisioning was that we (AT&T SDN) stored our numbers in ranges at the "extension" (xxxx) level; so as certain numbers were added, the range had to be separated out, reversed and added back. Confused yet? See the North American Numbering Plan Administration for more information on NPA splits.
Around 1995 our division decided to become CMM certified; this was a major initiative. At that time very few companies where even at CMM level II. My role in the initiative was centered on Configuration Management and documented how changes (requirements traceability) affected our software and how we deployed our software to the AT&T Network. While I was there, we did receive CMM level II.
