Differences between NEC 2000 IVS and IVS2

[aviateur]

I'm an IT guy that has been thrown in with what I believe is a NEC 2000 IVS PBX. I've been locked out of the system and contacted our vendor to help recover the password. Here's the problem, the vendor says we have an IVS2 because our LENs are 3 digits and not 4. I find it hard to believe that we have an IVS2 because the chassis says NEC 2000 IVS. How do I find out which PBX and software revisions we have?

Our vendor says to recover the password on an IVS2, they have to reset the system a couple of times along with a couple other things. Is there some documentation about recovering the password on these systems?

This could be a retrofit PBX (2000IVS cabinet with 2000IVS2 CPU).If you tell us what type of CPU you have we can figure ou what type of NEC 2000 it is.3 Digit LENS #'s are on the 2000IVS2 and 4 digit on the 2000IVS. If you need to recover a pwd on an IVS2 the system will need to come down once to get the password, not mutiple times! If it is an IVS the system does not need to come down!

In PIM0 there is a PN-CP16 which I believe is the CPU. There are PN-CP17s in all of the PIMs (PIM0-3).

Are there instructions on recovering the password anywhere or can you post how to recover it?

Thanks for the quick response.

End of story is if LEN numbers are 3 digit then it is an IVS2 even if it is a retro! For that matter it could be a retro IPS! I don't have the manuals to hand to check which a CP16 gives you but I think it is an IVS2.

Simple fact! if anyone posted a way to crack a password it would probably be wiped off the board immediately. We do not post ways to crack a password here, We are industry proffessionals. The system does not need to come down to crack the password so billyd3 obviously does not know what he or she is talking about! You need to get the password from your Vendor which they are obliged to give you by law! Otherwise you can get Nec to crack the password and if they charge for the service you can sue the vendor for costs! Remember it is your system not the vendor's and they have no right to lock you out of your system!

Whilst I agree that the post does show a way of circumventing the password it is a situation that should only be accessible to someone authorised to do it. I was referring to ways to hack the password without taking the machine down as NEC can do. I'm not so sure that post should be left on the board even though I contributed to it!

My apologies to billyd3 as well as he obviously does know what he is talking about! Just goes to show that even when you know the easy way it doesn't mean you know every way (perhaps it was an alzheimers moment considering my participation in the linked thread)!

Aviateur,
Since you have an CP16 this is an IVS2 Retro (IVS to IVS2 Upgrade), thought you might want to know for sure what type of PBX you have. See the link CTVI posted for instructions on how to get past the pwd. This was the exact procedure I had in mind!

Ozzie,
I was a little offended at your first reponse (I have been working on the NEC 2000 IVS, IVS2 IPS for about 10 years)I was glad to see that you apologized.
Apologie accepted!!!I would never post bogus information on this forum!!!!

Thank you for all of your replies. I will try the process in the link that ctvi posted.

Are there any forseeable issues with data loss when moving the switch on CP16 from 0 to 3 and then back again? Any precautions I need to take other than knowing this will drop all calls?

I suppose the problem is that I go all the way back to the 12 series (heck I even go back to plug and cord) and have had access to the inside word for too long. I've never had to use the process described in CTVI's link as I usually just hack it on line if I need to. The best tool I've recently got hold of is an AD8 password cracker. And before anyone asks I have to keep it in house!
