Check the circuit pack and wiring to see if you are using 2w or 4w circuit. If you have a 4w pack and wiring, you can use 302A/302B
In June 2001, the 302D Attendant Console replaced all sales of
the 302C Attendant Console (along with all prior models - 302A, 302B).
It is important to note that the 302D is 2-wire only and is backward compatible
to all 2-wire DEFINITY installations.
The 302As, 302Bs are 4-wire compatible only; where as the 302Cs are both 2-wire
and 4-wire compatible.
Product Migration Path:
The 302D Attendant Console is a viable replacement; however, the 302D is 2-wire
only compatible and the customer must address this in the event that 302As or
302Bs (both 4-wire) are being replaced (certain circuit cards will need to be
replaced with cards that support 2-wire at the customer's expense)
A great teacher, does not provide answers, but methods to teach others "How and where to find the answers"
