The last couple of days been getting a Yellow Alm on our TMDI card which locks out our DID/DOD trunks. This all started after last week taking a RED alarm on same ckt when the ATT T3 went down which our ckt rides across. I've been able to restore service by restarting the system, which I know is too drastic. I've checked the posts and found some info on using LD 60 to check the status. But would like to know the correct procedure to reset the trunks and or verifing the actual cause of the problem next time. Thanks
