Telco - Return

Introduction

Telco-Return provides downstream dataflow from cable modem cards connected to the cable system and accepts upstream traffic via a combination of the local PSTN and IP network path that terminates at the Cisco uBR7200. Upstream data is through a telephone modem connected to an analog telephone line which gives cable companies that have not upgraded their cable plants to bidirectional amplifiers, the ability to offer fast downstream data services via the cable plant and upstream transmission via the PSTN.
