The possibility that the processes responsible for the Cosmic X-ray Background (CXB) would also produce an e-e+ annihilation feature is examined. Under the assumption that these processes are thermal, the absence of a strong e-e+ annihilation feature places constraints on the compactness (L/R ratio) of these sources. Observations favor sources of small compactness ratio.
