- From: Tatsuya Kawasaki
- Date: Sat Dec 26 18:14:47 1998
(BI believe this type of leased line service is only in Japan.
(BDoes anyone explain the REAL different bwtn DA(digital accesss),
(BDR (ditial Reach) and true leased line called HSD?
(BBetter yet NO MORE DA NOR DR!!!!!!!!!!
(BI know from our experience, DA, DR are cheap and always gives us the
(Bproblem when either sides of leased line goes off, ie power failure.
(BIn the past, all I can do is to ask NTT to check the line, needless to
(Bsay the result comes back with OKAY but with not our supprise-- hey what
(Bwould I expect from NTT anyhow..., without changing anything, the network
(Bcomes back normal.
(BOnce someone explains in the past that it might be something to do with
(Belectric charge in DSU which "lock" circuit and when it is disconnected to
(Bcheck, it will be discharged and back to normal or something like
(BAnyone can add this or correct what I have just said.
(BSuggestion in either English or Japanese is accepted.
(BSincerely urgently yours,
