I have recently purchased a Channelized STM-1/OC3 SPA card for my 7600 router. framing is SDH and I need to use au-4 as my AUG mapping. Mux is mapping my first two tug-3 to a customer. Can I have these two tug-3 bundled into one serial interface? If can't what's the minimum number of serial interfaces that I can get?
I checked the configuration guide but couldn't find a good description....
