I purchased this board (a while back) and was told it supported both S/T and U interfaces. I can't find any docs on it and the folks at the Definity help line were less than helpful. I need to configure a U line with two station (not trunk) type b-Channels on it. Am I correct in that this board will do a U-Line and if so, how does the MDF breakout for this? Also, what station type do I assign? My switch is an R8 and the only option that looks like a possibility is WCBRI (world class BRI - not sure if this means generic BRI or something else). TIA, --SW
