Extracted from TFI's report:
As shown in the above forecast figure (Figure 6.1 in report), the growth of broadband lines on digital subscriber line (DSL) has helped stabilize the total number of incumbent local exchange carrier (ILEC) lines (narrowband and broadband) to about 180 million lines. However, as is clear from the forecast, even with the continued growth of broadband, soon the total number of ILEC lines will likely decline dramatically, because further additions in broadband connections cannot make up for the precipitous decline in narrowband access lines. Also illustrated is the forecast transition from standard broadband to very high speed (VHS) broadband.
