Dynamic mixing TDM data with data packets
First Claim
1. A method of combining TDM data and data packets comprising:
- receiving a plurality of TDM data columns;
receiving a plurality of data packets, transforming a first subset of the data packets into one or more TDM packet columns; and
combining the TDM packet columns with a first subset of the TDM data columns to form a data payload of an outgoing TDM data frame.

Abstract
To more fully utilize the available bandwidth of a network link, network nodes in accordance with the present invention allow TDM data to be combined with packet data. A Packet/TDM cross connect switch, having both a TDM switch and a packet switch, is used in these embodiments. Data packets are transformed into TDM packet columns. The TDM packet columns are combined with standard TDM data columns in the payload of a TDM data frame. Data packets may be sorted based on a priority scheme, in which high priority data packets are given precedence over lower priority data. However, both high priority and low priority may be combined in a TDM packet column
