What is a local loop?

The local loop is the physical link established from the demarcation point of the customer premises to the service provider’s network. To make it simple, the local loop is nothing more than a link between the above-mentioned ends. It’s important to mention that the local loop doesn’t necessarily comes from the service provider’s network, it can also come from a remote hub.
Local loops are capable of handling any type of connection because they were made to transfer information by means of different types of technologies, among them; ISDN, ADSL, HDSL, SDSL, VDSL.
Emphasizing the use of multiple technologies, we also have a wireless local loop, in which the last segment -which is generally wired- will be made by implementing a link via radio.
Another common expression for local loop is last mile, since it’s generally the maximum length that reaches the copper braid – the wiring – that goes from the service provider’s network to the place where the loop is located.
To put it briefly, this last node, or local loop, is the last link of the chain providing internet connection and land line services, thus reaching our homes through cable or radial distribution.
