Abstract
A telephony system having automatic timing adjustment for diverse routing of HFC systems has a signal stream routing through a signal line loop between a head-end and at least one communication unit , i.e., a cable modem cable access unit (CAU). If a fault occurs within the signal line loop, recognized by the head-end when a short uplink burst from the communication unit does not align within a predetermined timing window based on a value in the database, the head-end will adjust the cycle through predetermined delay parameters, corresponding to various alternate signal line loops made up of redundant signal lines. An information processor is provided at the head-end of the HFC system for automatically adjusting the timing of the signal stream in order to maintain the database determined at the information processor at the head-end . The timing adjustment of the signal stream is communicated between the head-end and the communication units, CAUs
