Patent ID: 7460554

Claim:
A method comprising: receiving a number of packets within a first Time Division Multiplexing (TDM) Synchronous Optical Network (SONET) signal having a number of SONET frames, wherein the packets are concatenated across any of the number of SONET frames within the first TDM SONET signal, such that a size of the concatenation can be in increments of single SONET frames assigned dynamically through provisioning data transmitted from control cards in any combination and apportioned to any configuration of input and output buffers; upon determining that the number of packets are being transmitted to a first location that cannot extract the number of packets from any of the number of SONET frames in the first TDM SONET signal, performing the following: extracting the number of packets from the first TDM SONET signal; filling a number of SONET frames in a second TDM SONET signal with transmission data that includes the number of packets, wherein the filling is equally interleaved across the number of SONET frames in the second TDM SONET signal and; transmitting the second TDM SONET signal to the first location; and upon determining that the number of packets are being transmitted to a second location that can extract the number of packets from any of the number of SONET frames in the first TDM SONET signal, transmitting the first TDM SONET signal to the second location.
