I don't know of 61000-4-16 coupling network for 1000Base-T, but I think maybe some of the manufactures of ISNs, or even 1000Base-T PoE injectors, can make such unit under special orders. However, maybe there is an alternative, cheaper solution. As you may know, 1000Base-T transceivers have circuit something like: http://pulseeng.com/products/datasheets/H544.pdf So, maybe we can open the AE such as Ethernet hub which will be connected to the port under test, find the capacitor, and inject the common mode disturbance at the terminals of the capacitor.
