In my mind NT5B01 is a NON-DS KSU and the rest (DS's) have 2 letters at the end NT5B01??.
I believe that the Used Phones link above that Carl posted is an NT5B01FD (hard to read but there is such a part) therefore yes that one is DS.
As for ATA2 my Nortel chart (actually from Nortel) only shows that ATA2 is not compatible with DR1...the rest are compatible. Standard ATA works on both DR1 and DR2 etc.
So I question that shortened 3rd party chart created by Nev-comm but if anyone can prove this theory it would be nice.
Do you need a Nortel Phone System technician or specific Nortel parts?
Atcom to the rescue! Our telephone techs have qualified experience servicing and troubleshooting Nortel CICS, MICS, & BCM telephone systems.
Service in Canada from sea to sea.
I just had a second look at that picture while closing it and appears to be a NON-DS DR1 software selling with a DS Cabinet, I don't think that will work out for whom ever buys it.
I have decided to leave this addition alone, as I have a pretty cool system that I like, I should add that I have already added 2 VoIP lines, and it works very well with this nortel system. I will still add the software that I was asked to show, very soon, and from this post I learned a lot, you guys really know your stuff, and are are a very big help so thank you.
On my shelf are 11 Panasonic phone systems. All of them have "ATA" capabilities and I have 7-10 Panasonic display phones and 3 TD1232 KSU's without looking too far into my storage place.
I have no idea if you bought the ATA or not, but I'd be willing to part with one of my systems and a phone for not a lot of money. That translates to $100-200 with shipping and most of these systems have CID trunks, but not to extensions.
Think about it.

That looks like the old entry level module that was called restricted in our area. A basic 4X8 config. Beyond that required a software cartridge replacement to get the other 2X8 ports.

Kind sir I really appreciate the offer, I really do, but at this point I already have the nortel 6x16 in service with 6 extensions and thorougly enjoy it and it fit my needs really well. And I have over 15 other nortel phones in my "overstock" as well. But thank you just the same. But as I learned here I have let go of the idea of adding on any ATA's for this system. I really appreciate everyone here in this forum. Carls offer is the kind of thing that makes this forum so great. So a kind thank you to all of you and Carl also.
