P25 emergency console dispatcher ack

[gesucks]

P25 emergency console ack. On a trunking system, when a subscriber sends an emergency the FNE sends an Ack message. The dispatcher can the send a difference ack message to confirm that in addition to the FNE seeing the emergency the dispatcher has seen it.

What I am looking for is 2 things.
1 is the dispatcher ack a P25 standard feature or a Moto feature
2. What is the response code for this? Is this a "90" feature?

Thanks!

This is on a P25 system

I think you mean "this is an Astro 25 system"

1. Standard feature

2. A "90" feature implies proprietary Motorola. As answered in #1, it's APCO 25 standard.

The opcode is 20 00 A7, same for both the FNE call processing as it is for the console. The only difference is FFFFFC vs FFFFFD
