VANs are private networks through which value-added carriers provide special data transmission services such as 911 service, 611 customer service, Caller ID, Voice mail, SMS, 4 digit dialing, Telemetry, as well as information lines for traffic and sports...etc. A Value-Added Network (VAN) simplifies the communications process by reducing the number of parties with which a company needs to communicate. The VAN accomplishes this by acting as an intermediary between business partners that share standards based or proprietary data.
