LLU：Local Loop Unbundled.
在FTTx + VDSL2场景下，铜线不是从CO开始的。
BSA：Bit Stream Access.
Background on ULL
The ULL charge is what other telecommunications companies pay Deutsche Telekom each month for provision of the unbundled local loop line, otherwise known as the last mile. In telecommunications networks, that refers to the section of line between the local exchange (main distribution frame) and the customer’s connection. In the case of the shorter ULL CD, the section of line between the cable distribution box (CD) on the street and the connection in the home, Deutsche Telekom has applied for a charge of EUR 8.80 per month (approved to date: EUR 7.17).
The unbundled local loop line is the most important wholesale service on the German telecommunications market, as it forms part of almost all wholesale products. The Federal Networks Agency has continuously cut the ULL charges since 1999 from EUR 12.98 to the current level of EUR 10.08; Telekom has consistently applied for higher charges in view of its cost statements. Deutsche Telekom currently leases out around 9.5 million ULLs.
And what now
Deutsche Telekom has filed an application with the Federal Network Agency for a monthly charge of EUR 12.37 for the provision of unbundled local loop (ULL) lines. For the first time, the approval period is three years with an option to extend for a further three years (until December 31, 2019). The current charge of EUR 10.08 expires on June 30, 2013.
