Station Message Detail Recording

Station Message Detail Recording
SMDR provides a printed record of your calls.
DSX | Features | 527
Station Message Detail Recording (SMDR) provides a record of the system’s outside calls. Typically, the record outputs to a customer-provided printer, terminal or SMDR data collection device. SMDR allows you to monitor the usage at each extension and line. This makes charge-back and traffc management easier. SMDR includes both incoming and outgoing calls, and can be turned off system-wide or selectively for each line.
The SMDR call record outputs when the call completes. The system assigns the SMDR record to the last extension on the call. For example, if extension 306 answers the call, talks for 20 minutes, and then transfers the call to extension 302, extension 302 “owns” the entire call record as soon as they hang up.
SMDR requires a customer-provided data collection device connected to the system’s RS-232 port. The default baud rate is 38,400. The data format is fxed at 8 data bits, no parity, with one stop bit (8N1). Connection requires:
• Adaptor P/N 1091014 to connect to the 9-pin RS-232 port on the data collection device.
• A standard 6-conductor line cord to connect the adaptor to the system’s RS-232 port.
SMDR does not buffer records when the data collection device is disconnected.
Call Duration Independent of System Clock
The duration of a call on the SMDR report is calculated independently of the system clock. This prevents changes made to the system Time and Date from inaccurately reporting the call duration after the Time and Date change. The automatic Daylight Savings Time adjustment also will not affect the call duration.
