Abstract

A signal band width limiter is provided in a telecommunication path that includes a leased unbundled subscriber line. The limiter may be a programmable active filter such as a digital signal processor in which filter characteristics are set under control of a controller at a central office. The controller may acquire the necessary subscriber level information via a data network from a data base at a remote location. Band pass ranges are set to frequencies corresponding to subscribed services. As the subscribed service is changed, replacement by the appropriate passband filter readily can be made. The telecommunication path can be monitored to determine whether an upgrade of service is required. Parameters of subscriber line leased from an ILEC by a CLEC can be tested at the ILEC premises.
