AMIS Operation Overview

AMIS analog networking operates in the following manner:

1. A local subscriber records a new message, forwards a message, or retrieves a saved message.
2. The subscriber addresses the message to a remote AMIS analog networking subscriber by using one-step or two-step addressing, depending on the configuration of the INTUITY system.
3. At the first available transmission period, AMIS analog networking dials the number of the remote machine to which the message was addressed:
   • If the message arrives during an active transmission period, the system attempts to make the outcall immediately. If the maximum number of simultaneous outcalling resources is busy, the system tries again in one minute.
   • If a port is available but the local system for some reason cannot deliver the AMIS message, the system makes two more attempts to deliver the AMIS message. The intervals at which the system tries to deliver messages are specified by the system administrator.
4. The AMIS analog networking system on the remote machine answers the call, exchanges protocols with the local machine, and allows the local machine to play the message.
5. The remote machine records the message in the mailbox of the subscriber to whom the message was addressed.
6. After the message is delivered successfully, the local system updates the outgoing message status to delivered. If all delivery attempts fail, the local system sends a new message to the sender to notify him or her that the message was undeliverable. The message is saved in the sender's outgoing mailbox so that the subscriber can attempt to send it again if desired.
7. The remote subscriber can now listen to the message.
