General Requirements

The E2M should (Not particular in this order):

If this is new (BAU)

• Update RM as today - If failed - Error (Like today) and don't continue (Like today
• Add the E2T address in the DB (As today)
• Put also KA Timestamp as NOW (As today)

If this is existing E2T (it means - KA didn't delete it 

• Put also KA Timestamp as NOW (BA)
• disconnect all existing RANs in the DB: Remove them from the E2T Instance list  and update Disconnect Status and remove E2T Address  in the RANs object (New)
• Update RM with disassociate RANs (New), but also if RM isn't responding, Error and continue.
• Don't send Setup, no need Setup Retry Counts

DoD:

New E2T - Runs it and see it sends us the E2T Initialize

• See HTTP request to RM with the right parameter
• See a new entry is added in the E2T
• See the KA is sent and it responds.

New E2T - But RM is down

• See HTTP request to RM with the right parameter
• See Error and no entry added in DB

Existing E2T which connected to 2 RANs

• See HTTP request to RM to disassociate the 2 RANs
• See list of RANs of this E2T Instance is empty
• See the 2 RANs are disconnected with no E2T address in their object
• See no Setup
