NEC 2400 1

[VoipNewbie]

Hey everyone,

I was wondering if anyone knew of any sites that would be helpful in getting familiar with this switch.

More importantly if someone could give me a breakdown of what the different lights across the top of the switch mean.... I know 3 are alarms but what could trigger these alarms?

any help is much appreciated.... thanks in advance!!

Hey thanks for the link to that site... lots of useful info up there....

One question to everyone... i found an error using the command DFTD in the mat terminal and the error i get is:

Can anyone help me decipher this message? and help me with a possible fix?

Also the yellow [SUP] alarm light is on ... on all of my switches... what normally causes something like that?

I used to see this alot on my 2400s with CCIS. In that case it was frame slips and CRC errors from time to time. Also would see that when power to the rectifier had gone out.

I would say that most likely this occurs in your ACD trunks with abandoned calls and things like that. If you haven't gotten any reports of trouble in the ACD queues I would reset the alarm RALM and not worry too much about it. If you see MN or MJ alarms, that's a different issue.
