This object is the total number of chunks sent on this specific association. This is the outbound half of the per-peer chunk volume, useful for confirming a specific association is actually transmitting the signaling traffic expected for that peer relationship, for example matching an expected call volume to a particular MGC. An association whose chunks-sent count stays flat at zero while others climb normally would indicate this device has effectively stopped sending anything to that one peer, even though the association itself may still show established.
