Abstract:
1. In an integrated services hub for coupling digital signals on a wide area network to and from analog signals in residential or business telecommunications equipment, the hub having a CPU controlling the operations of the hub, a CODEC, a local clock, an input buffer coupling digital signals received from the wide area network to the CODEC, the buffer implemented in memory operated by the CPU, and a baud rate generator in the CPU, a method for generating a sampling rate of coupling digital signals from the input buffer to the CODEC synchronized with a rate at which digital signals are received from the wide area network, comprising: using the CPU to produce a fill level indicator representative of the capacity of the buffer that contains digital signals received from the wide area network and not yet coupled to the CODEC, coupling the local clock to an input of the baud rate generator, using the CPU to generate a divisor coupled to the baud rate generator, using an output of the baud rate generator as the sampling rate for coupling digital signals from the input buffer to the CODEC, and adjusting the divisor to maintain the fill level of the input buffer within a preselected range.
