FAQ-1130 ESI SMDR Documentation

Function 18: Maintenance/SMDR serial port

As its name implies, the Maintenance/SMDR serial port provides not only SMDR data but also access to

system maintenance. Note: The system will buffer up to 1,000 SMDR records in non-volatile memory when the Maintenance/ SMDRserial port is in use for programming or uploading (such as during use of ESI System Programmer). If thebuffer becomes full, the system will discard the oldest records.



Real-time SMDR call records are continuously output to the SMDR port.

1. Select the output device by pressing the scroll keys (􀀂 and 􀀁):

• NONE (Making this selection ends the process at this step.)

• SERIAL (if connecting a printer or call accounting system).

• ETHERNET (if connecting to a LAN through an NSP board) — Skip to Step 3.

2. The system will then prompt you for the serial port baud rate. You can change this rate by pressing the scroll keys (􀀂 and 􀀁).

Options: 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200 bps.

Default: 38400.

3. Select the SMDR format, STANDARD or CSV, by pressing the scroll keys (􀀂 and 􀀁).

Default: STANDARD.



A laptop PC can be connected to this port for on-line programming and diagnostics. Reports (see “SMDR,” pp. L.1–L.3) are also output to this port. Maintenance mode begins for this port when you connect a PC to it and tap the PC’s Enter key. Baud rate for maintenance is the same as for SMDR (see “SMDR,” above).


Capturing SMDR data over Ethernet

The NSP can be used to output SMDR data over an IP network; and a Telnet connection can be made to the NSP, using port xx003 (default is 59003), to capture this data. For more information, see NSP Installation .
