Option 81C DCH limitation?

[bluetango]

I have Rel.25.40+. SLT says I can have up to 255 D-Channels. How do you configure an NT5D12xx Dual PRI w/NTBK51AA DCH Daughter, to go beyond the old 16 DCH limitation on the adress DIP switches? It's been I long time since I've had to configure one of these, and I just may be missing something obvious!

Thanks!

MSDL cards must be used instead of daughter boards to achieve the maximum.

in ld 96 when you stat msdl, does the switch ask group? if i remember right, your on the 1st rls that did. if so you have 16 device numbers per group, not 16 devices total like it used to be.. i have seen 30+ daughter boards.. with the msdl card 30 device numbers would give you 120, with the daughter boards, 60.. ld 96 map dch will give you a pretty good picture of the as built

Ok, Thanks Guys. Here's what I have. I am assuming that I can add more duaghter boards and use any of the unused addresses up to 16, on a per group basis.
