Mis-assigned Lines ATS has recently completed a mis-assigned lines case study involving a large ILEC. The study will be of immediate interest to any communications provider looking at their internal network to generate revenue and reduce cost. Mis-assigned lines can become a major problem among local exchange carriers. Thousands of lines are misallocated every year and the cost of these anomalies can reach into the millions. What is a Mis-assigned Line? A mis-assigned line is an access line physically located within a certain exchange, but with a NXX assigned to another exchange. This problem leads to customers not being charged for toll calls when they should and vice versa. Therefore, a communications provider might unknowingly be extending a caller's local calling area. What were the case study results? The ATS case study involved three digital switches belonging to a large ILEC operating over a vast amount of territory. On average, there were nearly 1000 mis-assigned lines per switch. For each of those lines, ATS conservatively assumed that 15 calls incorrectly result in charges for toll calls, or in no charges when there should be. In addition, it was assumed that 20% of those customers with mis-assigned lines resulted in trouble tickets. The average annual revenue loss per switch amounted to nearly $100,000. When multiplying these results across an entire network, the costs can reach into the millions. To solve this problem, a carrier would need either a data processing tool, or the ability to perform test calls and the resolve to spend months of tedious manual work routing out the mis-assigned lines. In this case, ATS used its powerful SimCall tool to help identify the mis-assigned lines for the ILEC in a very short time. |
