CHAPTER 2 Operations of SV8500 Server
10. STATION MESSAGE DETAIL RECORDING SYSTEM (SMDR)
Billing information can be managed by connecting Telephony Server and an external computer (SMDR
equipment).
Note: SMDR equipment and its software must be provided by the user.
The System provides the SMDR equipment with the following information:
• Calling Party Information
• Called Party Number
• Call Start Time
• Call End Time
• Call Data
• Authorization Code/Account Code
• Trunk Arrival Time (only for Incoming Call) Note
Note: Available in EU only.
Upon receiving the above information from the System, the SMDR equipment performs editing and manage-
ment of the information and outputs the resulting information. This section explains the information provided
to the SMDR equipment and also explains the method of controlling the interface port between the SMDR
equipment and Telephony Server.

As seen in the figure below, the basic information to be transmitted (Transmission Message) is a block
which begins with Start of Text (STX) and ends with End of Text (ETX). When the call ends, the whole
contents of this information is transmitted to the SMDR equipment.
