Claim:
1. A method for providing a flexible secondary data path control, said method comprising the steps of: a) detecting a primary data path failure of a primary data path between a customer premise site and a central office site; b) initiating a corresponding secondary data path if a primary data path failure of said primary data path has been detected; c) proceeding with at least one of: d) determining services to be provided via said secondary data path depending on the measured data path characteristics of said secondary data path, wherein secondary links of a backup network infrastructure offer non-constant, non-predictable bit rates and asymmetric bit rates for an uplink and downlink connection, and said non-constant, non-predictable bit rates and asymmetric bit rates demand a flexible adjustment and an associated data traffic flow to cope with these data rate changes, and wherein said primary data path and said secondary data path are tested constantly to detect path changes or path failures of said primary data path and secondary data path, and wherein the measurement of the primary data path and said secondary data path does not impair or harm user traffic or service traffic, and wherein the secondary data path is used until the primary data path returns to a normal operation state, wherein said secondary data path includes different backup infrastructures with corresponding different path metrics; and wherein said backup infrastructures of said secondary data path comprises a wireless network infrastructure including a CDMA, GSM EDGE, UMTS, LTE or WIMAX network and/or a microwave-based connection and/or a satellite-based connection.
