This can be the result of issues such as connection problems or a loop's inability to support a given DSL service. In these cases, the field technician must coordinate additional testing with a NOC-based technician. As any NOC manager knows, having the right number of people available to handle these types of requests is a constant juggling act. If you have too few, the field technician must wait usually under the watchful eye of the customer. If you have too many, it is costly and inefficient.
Some difficulties can take many hours to resolve.
Having NOC technicians and engineers tied up during this entire process is very inefficient. By enabling field technicians to access all of the loop management functionality available in the NOC, they can independently solve problems and turn up services faster. Fewer personnel are involved. A service provider's resources are conserved. The DSL landscape is getting increasingly more competitive, and companies must find ways to do more with fewer people.
