Station Message Detail Recording
Description
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 traffic 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 fixed at 8 data bits, no parity, with one stop bit (8N1). Connec-
tion 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.
