| is there a csu/dsu beetween the t1 smartjack and the tda system?
if so, try bypassing it or replacing it. panasonic requests that you have a csu/dsu, but the t1/pri should work without it. that goes for a straight pri circuit, not sure about the fractional t1/pri. could be that the adtran is faulty.
back in 2005, i handled the phone system for nyc mayoral candidate "Freddy ferrer" campaign headquarters. they started having t1 lockups and cutoffs durring high traffic like your customer, we tried everything, with no luck. as a last resort i just bypassed the adtran csu/dsu and the problems disapearred. the t1 worked flawlessly without the adtran unit for the next 2 months when he lost and closed the office.
since you have a fractional pri, you might not be able to bypass the adtran but if resetting your adtran temporarily solves your problem then i would suspect that the adtran might be faulty. your dealer might be able to get an advanced replacement unit from adtran to swapp it out with.
if the problems happens only during high traffic, i doubt that it is faulty programming in the panasonic. |
