Hy everyone!

I work on board of passenger ship and I am in charge whit telephone system (ERICSSON MD110), I take over the job from communication off. and I don't have experience whit it.
Due a water pipe break on top of one of the LIM's I face some big issues. First I lost the power supply, and I replaced whit 4 battery in series to get 48V to power up the back the LIM. after this I lost the background tone on all the phones assigned to this LIM. can anyone help me whit some suggestions?

Hi, if you can make and receive calls but no background dial tone, swap the TMU(2) card(s) in Lim 8 as the dial tone comes from TMU (‘s)
