Multi-Node 5000 and an Axxess 911 notification

[AAdivot]

I know how to make 2 5000's or MiVoice 250's notify a single operator of 911 calls.
- Operator A who is on Node 1, gets 911 notifications of 911 calls made by extensions on Node 1.
- Operator A who is on Node 1, also gets 911 notifications of 911 calls made by extensions on Node 2.
That is with 2 5000's.
Does anyone know if that can work, with an Axxess cabinet as node 3?
I hesitate to mess around with the stop bits without even knowing if it will work or not.
- So that, operator A, on Node 1 of the 5000, gets notifications of 911 calls made by extensions on Node 3 - An Axxess?
5000's are 6.2 and the Axxess is 11.
