US 8,542,694 B1 · System and method for packet and time division multiplexed transport

Abstract

A system and method are presented for providing packet and time division multiplex (TDM) services in a data communication interface. The method accepts packets at a first rate over a packet interface, and transfers time-sensitive data in the packets as packet data units (PDUs) having a smaller number of bits than a packet and a second rate, faster than the first rate. The method transforms the PDUs into frames in a first TDM protocol. Typically, the PDUs are transformed into units having a smaller number of bits than the PDU and a third rate, faster than the second rate. Then, the TDM frames are transmitted over a line interface.

Dependent claims

In a data communication interface, a method for providing packet and time division multiplexed (TDM) services, the method comprising:

receiving TDM data of a second TDM format;
generating frames from the TDM data in a first TDM format;
isolating frames containing time-sensitive data and frames containing non-time-sensitive data;
forwarding frames in the first TDM format containing non-time-sensitive data using flow-control over a first TDM interface to a packet processor;
forwarding frames containing time-sensitive data in the first TDM format over a second TDM interface to a timing processor.
