I have a client with MICS, 4.1, PRI and a NAM. Today they could not make or recieve calls. I cheked the network alarms and it had Alarm 73 and event code 799-0001oes7. Does anybody know what these are refering to. I saw another post hear that asked the same question, but there was no answer as to what the alarm meant.

Alarm 73 states "No DN is available to the new ISDN-S loop terminal.
Action - A DN may be made available by changing the DN type from portable to ISDN. If no portable DN can be changed, a DN can only be available by unplugging an S-loop terminal.


I know a little about a lot, and a lot about little.

Thanks for the reply zsmilesss. This system has been working for 6 years and this is the first time that i have seen this alarm. Could you tell me what a DN can only be available by unplugging an S-loop terminal is refering to. How do I go about fixing this.

thanks
