1. An apparatus for sending tandem-free operation (TFO) frames to a destination communication system, comprising:
- a first extraction element configured to extract TFO information from a first TFO frame received from a compatible communication system;
a second extraction element configured to extract TFO information from a second TFO frame received from a non-compatible communication system; and
a selection element communicatively coupled to the first extraction element and the second extraction element, wherein the selection element is configured to select either extraction element depending upon whether a received frame is from the compatible communication system or the non-compatible communication systems,wherein if the extraction element'"'"'s frame is received from the non-compatible communication system, then it is reconstructed prior to being forwarded to the destination communication system.

Abstract
Tandem-free vocoder operations (TFO) between non-compatible communication systems may be enabled through hardware modifications at communication elements within each system. In one aspect, each infrastructure entity in System 1 comprises an intra-system TFO Frame Generator G1, an intra-system TFO Frame Extractor E1, and a TFO Frame Extractor E2 of System 2, which is non-compatible to System 1. Each infrastructure entity in System 2 comprises an intra-system TFO Frame Generator G2, an intra-system TFO Frame Extractor E2, and a TFO Frame Extractor E1 of System 1.

6. A method for harmonizing a tandem-free operation (TFO) feature of a first communication system with a TFO feature of a second communication system, comprising:
-
at a first infrastructure entity of the first communication system, determining extraction capabilities of a second infrastructure entity of the second communication system; selecting an appropriate TFO frame format; encapsulating a vocoder frame into a TFO frame using the appropriate TFO frame format; transmitting the TFO frame to the second infrastructure entity; receiving the TFO frame at the second infrastructure entity; determining a vocoder source type of the TFO frame; extracting the contents of the TFO frame according to the vocoder source type of the TFO frame.
