In telephony, a local loop refers to the connection between a telecommunication company's CO to the lines in the service subscriber's home or office. Originally, local loop service carried only telephone service to subscribers. But today, with the use of modems, ISDN and DSL signals are transmitted to subscribers as well through the local loop.

CO

Short for central office. In telephony, a CO is a telecommunications office centralized in a specific locality to handle the telephone service for that locality. Telephone lines are connected to the CO on a local loop. The CO switches calls between local service and long-distance service. ISDN and DSL signals also channel through the CO.
