Note: Data are only available for reporting years 1998 through 2007. Effective 09/06/2008, subsequent years' data are no longer reported. |
Purpose: This report provides a view over time of the ratio of Total Switched Access Lines in Service to Central-Office Terminated Fiber Strands. These comparisons are made for those telephone companies required to file the ARMIS 43-07 report, i.e., incumbent local exchange carriers subject to mandatory price cap regulation. Data are available for several user-selectable levels of aggregation, andare displayed by year under the current corporate structures, for the most recent 10-year period.
Source: ARMIS 43-07, Table I, column (a) Total Study Area, row 120 Total Number Access Lines in Service, and Table II, Column (d) Total Study Area, row 480 Fiber Strands Terminated in the CO (Loop Plant).
Content:Results may be selected and displayed for the following aggregations:
· Large ILEC Region: AT&T, Qwest, and Verizon - results for each of these three companies (based on combined study areas for each of the three), plus the combined results of all three companies.
· Large ILEC Holding Company: Results for each of the eight large ILEC holding companies (BellSouth, Qwest, Southwestern Bell, Pacific Telesis, Southern New England, Ameritech, Verizon-Bell Atlantic, Verizon-GTE), plus the combined results of all eight holding companies.
· State: Results at the study area for AT&T, Qwest, and Verizon companies (as applicable) within the selected state, plus the combined results for all large LECs in that state.
Method:The 1991 through 1996 values for Table I, row 120, column (a) are first multiplied by 1,000. The ratios of access lines to fiber strands are calculated by dividing row 120 in Table I by row 480 in Table II. Note: where a row 480 value is 0 (zero), the quotient is not calculated. Instead, output result is “N/A”. All quotients are expressed as whole numbers. Also, ARMIS Report data for companies who have not filed any ARMIS data more recently than the fifth year preceding the current year are not available in the system, i.e., if the last year in which a company filed ARMIS data is 2002 or earlier, then no ARMIS data for that company is in the system.
