pi^7 ?

I have to make the PCB RF and RC parts on Eagle. I found a library which has LFCN pieces already built. I'm guessing I would need to name them appropriately (800 1450 ...) but can anyone guide me on what the pi^7 means?

So the LFCN parts are pi filters. The 80, 1450 and 5000 are specifying the passband where the attenuation < 1dB i.e DC-80MHz, DC-1.45GHz and DC-5GHz. The 7 is the number of sections in the pi filter as far as I can tell.
