An initialisation protocol for a TDMA based QPSK burst-mode transportation system for use on shared medium networks such as cable TV networks is described. Cable TV networks employ the coaxial bus principle between an optical node and the client modem. Each cable modem connected to the coaxial bus needs to undergo a start-up procedure at activation to determine certain timing and physical layer related settings. The mechanism described here performs identification of a modem, power ranging and distance ranging. A unique distance ranging mechanism is employed that offers delay ranging based on distribution power measurement.

Abstracf -An initialization protocol falr a CDMA based communications system for Hybrid Fiber Coax (HFC) Central Antenna Television (CATV) networks is described. HFC CATV networks are shared medium access networks, employing the coaxial bus principle between an optical network terminator and the subscriber. TID realize access in the upstream direction, a multiple access scheme based on CDMA can be used [1,2,3]. However, before access is granted in the upstream direction, each cable modem connected to the coaxial bus needs to undergo a startup procedure at activation of the modem to determine timing and physical layer related settings. The initialization mechanism described here performs time synchronization of a modem and the determination of the power the modem should use. Next to these physical layer settings, also the identity of a modem is determined during the initialization process.
