I am a certified Lucent 5ESS tech and have never heard of any lowering or raising a layer. I do know of two types of ISDN which the one you would most likely use is National. The other one is Custom and I know for a fact you don't have that one. Maybe your terms are different from mine, just what is this low or high supposed to do?
