RE: J12001-06-06 04:40:02are sure of that. What I mean is the notation E1/T1/J1 Sorry; those are time-division telephone trunk lines. J1 is the Japanese version of T1, with 23 telephone channels. I am sure it is cited in SS7, and belongs in ITU-T's Q-series, but there is a good chance that NTT Japan hasn't gone to the silly expense of that process. Cheers, James
