Abstract: A hybrid IP/ATM NT and method are provided for hybrid IP/ATM network termination. While traversing a DSLAM, ATM traffic over ATM network infrastructure and GigE/IP traffic over GigE/IP network infrastructure may be recast into crossover GigE/IP traffic and crossover ATM traffic respectively, and routed to the opposite kind of network infrastructure with use of the IP/ATM NT and hybrid IP/ATM network termination.

Abstract: A metastability filtering circuit comprising: a sampling circuit for sampling a first clock signal with a second clock signal to produce a sampled first clock signal, the first clock signal being synchronous to an interface between first and second systems; an edge detection circuit coupled to the sampling circuit for receiving the sampled first clock signal and for producing a rate adapted first clock signal; a delay circuit coupled to the edge detection circuit for receiving the rate adapted first clock signal and for producing first and second clock enable signals, the second clock enable signal being a delayed version of the first clock enable signal; and, a shift register clocked by the second clock signal and having first and second sequential registers enabled by the first and second clock enable signals, respectively, for receiving an input signal from the first system at the first register and providing a filtered output signal to the second system from the second register, wherein the filtered outpu
