    摘要: A system and method for determining a correspondence between an Abis signaling channel and an air channel frequency designator. A monitoring instrument may be connected to multiple E1 circuits, monitoring messages sent on Abis signaling channels. By repeatedly observing channel activation messages (135) preceding channel assignment messages (145) of interest, or channel assignment messages (145) following channel activation messages (135) of interest, the instrument may infer a correspondence between an Abis signaling channel and an air channel frequency designator.
