NTDK20 Vintages

NTDK20 Vintages

(OP)
Hey folks,

Have a simple question with respect to the correct way to identify NTDK20 vintages. In short, how do I tell which NTDK20 SSC is newer and which is older. Is it simply that NTDK20xA where the 'x' increments alphabetically? So, NTDK20FA is older than an NTDK20GA which is older than an NTDK20JA?

I've seen the following posts but am still unclear (perhaps I have the dumb):

Thank you in advance for any advice and guidance :)

Cheers,
bc

RE: NTDK20 Vintages

I would say yes, for the most part, the ascending letters would indicate a newer vintage card.

An existing Option 11C system equipped with a controller card NTDK20AB can be upgraded to an NTDK20CA with a field upgrade kit NTDK19AA. As of July 1999, all controller cards shipped to the field have been a minimum of NTDK20DA, which is compatible with Release 25 and Succession 3.
A system upgrading to Release 25 or Succession 3 must replace its NTDK21 (32 MB) or NTDK81 (40 MB) based software daughterboard, with an NTTK13AA (48 MB) or NTTK25AA daughterboard. Please ensure that you have upgraded the bootcode on the SSC prior to upgrading the software daughterboard. To verify the size of the software daughterboard and for installation instructions, refer to NTP upgrade manual Chapter 9.
The Succession Branch Office Call Server requires a 48MB Total Memory (32 MB Program Store and 16 MB CDrive space) in order to run Succession 3.0 Software.
