Sub-loop unbundling

Sub-loop unbundling is the process by which a sub-section of part of the local loop is unbundled. In practice this often means the competitor placing a small street cabinet next to a telco local copper aggregation cabinet or Serving area interface and using a `tie cable’ to connect on to the last part of the local op into customers’ homes. Being short range, superior bit-rate performance will result compared to normal Local loop unbundling (LLU).
