Digital networking

Digital networking is the transfer of a digital file from a subscriber on one system to a subscriber on another system. Voice and fax messages are files that are digitally recorded and stored. Digital networking allows these messages to be transferred from one remote machine to another using Message Networking.

A digital message is sent in the following manner:

1. A subscriber on a remote machine records a voice message or creates a fax or email message and then addresses it to a subscriber on a different remote machine.

   Notes:

   • Fax is supported on Aria and Serenade Digital, DEFINITY ONE Release 2.0, and systems using the VPIM V2 protocol. Email is supported on INTUITY AUDIX Release 4.0 or later, DEFINITY ONE Release 2.0, and systems using the VPIM V2 protocol. INTUITY digital networking and SMTP/MIME can pass text and binary files.
   • Digital networking on the Message Networking system uses an IP address since the digital protocol is TCP/IP.
2. Message Networking answers the call and identifies the remote machine and subscriber to whom the message is being sent.
3. Message Networking sends the message, including a message header (remote machine name, sender's name, time message was sent, and length of message), to the remote subscriber.
4. For AUDIX, the subscriber sending the message receives notification that the message was received.

TCP/IP is used to communicate with INTUITY AUDIX Release 4.0 or later, Aria Digital, Serenade Digital, VPIM V2, and SMTP/MIME digital systems, as well as between Message Networking systems.

TCP/IP networking has some impact on the amount of traffic over a system's LAN connection. You can calculate this impact by multiplying the number of networked messages by the number of packets and/or number of bytes per message.

TCP/IP networking LAN traffic example

For AUDIX, during the busy hour, a single remote system generates 150 voice messages, 30 fax messages, and 50 email messages using TCP/IP networking. The impact on the LAN can be calculated as follows:
