Abstract:
1. A gateway, comprising: a demodulator/DOCSIS media access controller (MAC) configured to demodulate and to format a voice signal and a data signal according to a Data Over Cable Service Interface Specification (DOCSIS) protocol to produce a DOCSIS formatted voice signal and a DOCSIS formatted data signal; a voice processor configured to provide a processed voice sample based on the DOCSIS formatted voice signal; a first voice queue configured to store the processed voice sample; a voice synchronizer configured to up-sample a first stored voice sample from the first voice queue by a ratio of a first count to a second count when the first count is greater than the second count and to down-sample the first stored voice sample by the ratio of the first count to the second count when the first count is less than or equal to the second count to provide a re-sampled voice sample; a second voice queue configured to store the re-sampled voice sample; and a digital to analog converter (DAC) configured to convert a second stored sample from the second voice queue from a digital representation to an analog representation, the gateway being configured such that a rate at which the DAC removes the second stored sample is substantially equivalent to a rate at which the second stored sample is inserted into the second voice queue.
