    "abstract": "Telephone return cable modem systems provide a way to obtain early experience in the integration of data networks with cable access methods. For many current cable service areas, e.g. those that are small or sparsely populated, telephone return may be a viable long term technology for delivery of high speed data services. This paper summarizes the network design issues and approaches of the first generation of commercially deployed telephone return cable modems.",
