LEC Line Loss Summary, 2007
For the past week, I've been digging into the massive losses in Local Exchange Carrier Switched Access lines, trying to quantify where all of these lines are going. I looked at how cable voice services, fixed-mobile substitution, and VoIP are all contributing to LEC line losses. Now it's time to summarize all of the data in a single table:
| LEC Access Line Migration, 2007 | EOY 2006 | EOY 2007 | Change in "Lines" | Estimated Contribution to LEC Line Losses |
| AT&T (landlines) | 66,469,000 | 61,582,000 | (4,887,000) | (4,887,000) |
| Verizon (landlines) | 45,100,000 | 41,441,000 | (3,659,000) | (3,659,000) |
| Qwest | 12,299,465 | 11,500,000 | (799,465) | (799,465) |
| Comcast Digital Voice | 1,900,000 | 4,377,000 | 2,477,000 | 2,477,000 |
| Time Warner Cable Voice | 1,860,000 | 2,900,000 | 1,040,000 | 1,040,000 |
| CableVision Voice | 1,209,000 | 1,592,000 | 383,000 | 383,000 |
| Charter Voice | 445,800 | 959,300 | 513,500 | 513,500 |
| Vonage | 2,224,111 | 2,580,227 | 356,116 | 213,670 |
| Skype Real Users in USA* | 6,230,000 | 8,000,000 | 1,770,000 | 0 |
| AT&T (wireless) | 60,962,000 | 70,067,000 | 9,105,000 | 1,379,853 |
| Verizon Wireless | 59,029,650 | 65,700,000 | 6,670,350 | 1,010,884 |
| Sprint Nextel | 53,100,000 | 53,800,000 | 700,000 | 106,084 |
| T-Mobile USA | 25,041,000 | 28,685,000 | 3,644,000 | 552,244 |

| Leap Wireless | 2,226,000 | 2,860,000 | 634,000 | 96,082 |
| Estimated Other Cable Line Migration | 367,792 | |||
| Estimated Other Wireless Line Migration | 93,455 | |||
| Estimated Other VoIP Line Migration | 28,036 | |||
| Estimated Business Line Migration | 467,273 | |||
| Estimated Fax and Modem Line Disconnection | 461,740 | |||
| Total | - |
*Note: Skype "Real Users" figures are from Hudson Barton's Borderless Communicator blog. He has an interesting related post on the LEC line loss theme today.
To create this table I relied on data from annual reports of public companies, data from the FCC Annual Report and Analysis of Competitive Market Conditions With Respect to Commercial Mobile Services, comments from Telecosm readers, and a little guesswork on the margins.
Estimating fixed-mobile substitution is the hard part of this table. The FCC report estimates that between the 2nd half of 2005 and the 2nd half of 2006, the percentage of U.S. households that only had wireless phone service grew about 4% to something between 11% and 12% of all 110M U.S. households. I'm guessing that by the end of 2007 the percentage of U.S. households that used wireless as their primary phone line had grown to about 15.3%. However, some of the incremental growth in wireless-only households did not switch from LEC services, instead switching from cable and other VoIP services, so I tried to account for that in the table.
The "Estimated Other Cable Line Migration" is estimated at 4% of the total line losses at the big three LECs, to account for Cox Communications, who is privately held, and to account for the host of smaller cable companies.
I'm guessing that VoIP accounted for only about 2.6% of the overall LEC line losses in 2007, due to the fact that some of Vonage's customers are overseas, and to account for the fact that VoIP providers struggled or went out of business in 2007 (SunRocket).
The pie chart below summarizes the data for the major causes of LEC Line Losses:

Interesting stuff, that seems on target. But I'm trying to figure out how you calculated the telco to cable line loss. It's not obvious to me how to be precise about that.
Thanks
