SMDR
Using SMDR (Figure 5-1)
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. Use SMDR when
you need to monitor the usage at each extension and trunk.
The following devices can be used to output SMDR from the system:
● CTA
● CTU
● NTCPU’s Serial Port
● NTCPU’s Ethernet Port
Installing SMDR
1. Install the DCI device to be used (refer to the specific CTA/CTU information described previously).
If using a CTU’s USB connector, a driver is required. The driver can be downloaded from
NEC’s Technical Support web site (ws1.necii.com). Refer to the CTU Adapter (Figure 4-43 - Fig-
ure 4-45) (page 4-44) for details on installing the driver.
2. Install the SMDR recording device according to the manufacturer’s instructions.
3. Connect the SMDR recording device to the telephone’s CTA/CTU.
Note: When using a CTA, a straight through RS-232C cable terminated with a 9-pin
female connector is required. Refer to the pin-out information in Figure 5-1.
Note: When using a CTU , a standard USB cable (USB Type B Male-to-USB Type A Male)
is required.
Note: When using the NTCPU ethernet port, a standard ethernet cross-over cable is required.
Note: When using the CPU’s serial connector, a null modem cable is required. This cable
is available from NEC as part number 0892004 or refer to the pin-out information
below to make your own cable.
