Abstract:
1. A method for converting a data stream comprising first data having a plurality of first data packets and idle bytes interposed therebetween received from a broadband network to another data stream, comprising second data having the plurality of second data packets for communication on a payload network having a narrower bandwidth than said broadband network, said payload network having two channels, method comprising receiving the first data from the broadband network; converting said first data into a serial data-stream; identifying idle bytes and non-idle bytes in said serial data-stream; removing said idle bytes from said first data thereby providing a reduced data; providing said reduced data to one or another of said two channels of said payload network as follows: writing said non-idle bytes into a first buffer if space is available therein; writing said non-idle bytes into a second buffer if space is not available in said first buffer; writing a place keeping flag into said first and second buffers in substitution of an idle byte omitted from the data stream stored therein; outputting said non-idle bytes from each of said first and second buffers; and converting said outputted non-idle bytes into respective said second data packets.
