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 loop plant fiber to loop plant copper facilities, 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, and are displayed by year under the current corporate structures, for the most recent 10-year period.
Source: ARMIS 43-07, Table II, column (d) Total Study Area, row 470 Copper Pairs Terminating on the Main Frame (Loop Plant Only), and row 480 Fiber Strands Terminated in the CO (Loop Plant Only).
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 ratios of fiber to copper facilities are calculated as follows: divide row 480 by row 470, and express all quotients as percentages rounded to two decimal places. 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.
