Hi all, i have a similar issue as this thread :thread963-1305300
dtu-ph gone from ins to abl-fail
tried to change board a changing position in shelf, but still got the problem
protocol used is dpnss

should it depend from crue entry ???

hi Morry70

eprom set is OK for dpnss ?
for dtuph there are 2 sets of different eprom for ISDN(pack 140)/ DPNSS (pack130)
if eprom set is correct ,test if loop tx/rx the board goes into service
bye

hi bftel
thanks for answering

in the meanwhile i've solved,
all was relate to a provider issue ( part of interconnection between the two sites was misconfigured)
So now i know that if the link is faulty...... nothing works !!!!
