System and Method for Multiplexing PDH and Packet Data
First Claim
1. In a method where data from plural plesiochronous digital hierarchy (PDH) sources and from a packet source are received, assigned to bit positions in a frame, and transmitted as a single data stream the improvement wherein the data received from the packet source is arranged in the data stream as a function of a synchronized data rate of the received PDH sources.

Abstract
A method of efficiently combining data from at least a plurality of a first type of data source and a second type of data source. The method comprises synchronizing the plural first type of data sources to thereby generate a synchronized data rate, providing a frame having plural bit positions, assigning the synchronized first type of data in ones of the bit positions of the frame, and arranging the second type of data in the frame as a function of the synchronized data rate.

2. A method of transmitting data received from plural sources that are not synchronized with each other and a packet source as a single data stream comprising the steps of:
-
synchronizing data received from the plural sources that are not synchronized with each other to thereby generate a synchronized data rate; providing a frame format comprising a plurality of frames each frame having plural sub-frames the number of which correlates to the number of received plural sources that are not synchronized with each other and each sub-frame comprising a plurality of blocks each block comprising; at least one overhead bit position, (n) bit positions of the synchronized data, (m) bit positions of data received from the packet source arranged as a function of the synchronized data rate, and a plurality of sub-blocks each having a bit position for the synchronized data or a bit position for data received from the packet source; assigning the synchronized data and data received from the packet source in bit positions of the frame format; and
transmitting the assigned data as a single data stream. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)

10. A system adaptable to receive data from plural first type of data sources and at least one second type of data source that are not synchronized with each other and to transmit the data as a single data stream,
wherein if data from both the plural first type of data source and second type of data source are received, the plural first type of data source is synchronized to thereby generate a synchronized data rate, a frame is provided having plural bit positions, the synchronized first type of data are assigned in ones of the bit positions of the frame format, and the second type of data are arranged in the frame format as a function of the synchronized data rate for transmission thereof, wherein if data from only the first type of data source is received, the plural first type of data source is synchronized to thereby generate a synchronized data rate, a frame format is provided having plural bit positions, and the synchronized first type of data are assigned in ones of the bit positions of the frame format for transmission thereof, wherein if data from only the second type of data source is received, a frame format is provided having plural bit positions and the second type of data are arranged in the frame format for transmission thereof.
