A service to a user is prevented by providing, to the user, at least one communication link used to provide multiple services to the user. The plurality of services are activated over the at least one communication link. Transmission for the prevented service is prevented based on at least one characteristic of the at least one communication link over which the prevented service would be provided.

Method and apparatus for spectral containment over telephone service lines

A method for providing spectral containment over telecommunications service lines is provided. The method includes selecting a filter having spectral characteristics corresponding to a predetermined passband. The method also includes connecting the filter in series to at least one loop used to provide at least one telecommunications service to a customer. The method further includes activating service over the at least one loop. The filter attenuates signals transmitted on frequencies outside of the predetermined passband over the at least one loop.

A filter passing only desired frequencies is selected according to a desired level of service for copper lines. At a point of access between a loop plant and Central Office, the filter is interposed in series over a telephone service line to provide spectral containment by restricting the frequencies of transmission passing along the line. The filter is preferably mounted within a 5-pin module used in a protector block at the Central Office or remote terminal facility, interfaces with a 5-pin module, or is placed upstream or downstream of a protector block such that it does not interfere with the operation thereof. Service is activated, and the spectral containment apparatus prevents the transmission of unexpected or unintended services over the line.

At a point of access between a loop plant and Central Office, the filter is interposed in series over a telephone service line to provide spectral containment by restricting the frequencies of transmission passing along the line. The filter is preferably mounted within a 6-pin module used in a protector block at the Central Office or remote terminal facility, interfaces with a 5-pin module, or is placed upstream or downstream of a protector block such that it does not interfere with the operation thereof. Service is activated, and the spectral containment apparatus prevents the transmission of unexpected or unintended services over the line.
