Bellcore 4.5.9 Intrabuilding lightning calls for testing with 2/10us waves, but as David says, allows for the use of resistor networks added on to a 1.2/50us generator. 2/10 generators for both 2 and 4 wire applications are available for roughly the same price David paid for the Schaffner unit, plus they can be expanded to perform the other Bellcore tests as well. The KeyTek generator mentioned is much less expensive but then you need to build the resistor networks to meet the spec --
You may find it difficult to get the power resistors required: they need to be non-inductive and capable of handling both the voltage (>1500V) plus the 100A surge currents. Let me know if you need help there.
