I contacted one of the MTI Milliren marketing guys a few days ago, and got some specs on the MTI model 260-0624C and 260-0544C OXCOs that are currently being sold on Ebay. the model 260-0624C is the one used in the Lucent /Symmetricom Z3810A systems. The model 260 is advertised as being close to a Rb in performance. This is all the data that he would give me since I wasn't the original customer for whom they were made. He also says these models are still in low volume production for the customers.
