Norstar 8x24 requirements for old 1A2 trunk module ...

[DominicUCx]

Does anyone have the documentation and compatibility matrix for this?

Which version of Modular 8x24 did it work with? Centrex module required? Disconnect Supervision (OSI)?
Wiring diagram for A lead control?

Can't find anything online, but we have a 1A2 (NE-QUJ8A) with 4 loop start analog trunks with 850ms DS and would get a kick out of reconnecting the two units together.

Try searching Part NT5B39

DR3 to DR5 that I know of.

No PDF's in those days for the guides but wait for a guru to reply.

No, I need details.

I know I need the Centrex software which came out around the time 824 DR3 did Curly, not the Centrex+ one which come out later, and an external copper trunk module. No idea how to wire the RJ21 without the mapping. T, R, A, A1 for 4 CO lines. Programming would be simple.

I need that mapping.
