This technical report describes voiceband transmission performance parameter levels of voicegrade analog unbundled subscriber access (section 4)@ local access lines terminated at the NI at one end and the end office switching system at the other (section 5)@ and treated lines (section 6). In addition the technical report describes traditional and existing methods of ILEC loop facility design integral to local access service. The technical report contains information which should be useful in CLEC design of local access lines regardless of the loop transport technology employed. Purpose In order to stimulate competition@ the Telecommunications Act of 1996 (TA96) allows for Competitive Local Exchange Carriers (CLECs) to offer switched local network services to their (retail) telecommunications customers. CLECs may obtain part or all of the physical means for providing these services from the Incumbent Local Exchange Carriers (ILECs). The purpose of this technical report is to help the telecommunications industry plan quality@ voiceband transmission performance on unbundled voicegrade analog loops. Therefore@ the technical report describes transmission performance parameters of unbundled loops used to provide connectivity to a subscribers' premises for analog voiceband services. The technical report is as quantitative as available sources permit. The information in this document will help the industry to cooperatively meet objectives for providing end-user analog voiceband services. This document fosters the provision of quality end-to-end service@ as perceived by the end-user of analog voiceband services. This document is written in the context of a carrier purchasing connectivity to the enduser@ i.e.@ subscriber access. The document focuses only on analog voiceband services.
