1.652 Symmetricom-XLI

This page describes the device driver and the device window for the Symmetricom XLI Time and frequency system.

The driver was tested in 1:1 configuration with the following SW Releases:

• SW: 192-8001

Please note that SNMP is disabled by factory default. Therefore change snmp.conf via WebUI.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- The device switch parameters
• --- The faults page.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the controller.

• parameter --- description

• address --- The SNMP address specification for the device. The full address specification consists of the following fields:aaa.bbb.ccc.ddd:pppp read-community write-community

  • aaa.bbb.ccc.ddd --- The IP address of the device in 'dotted quad' notation. This field is mandatory.
  • pppp --- The IP port number where the device accepts SNMP requests. The port number may be omitted, the driver uses the standard port 161 in this case.
  • read-community --- The SNMP read community name. This must match the read community expected by the device.
  • write-community --- The SNMP write community name. This must match the write community expected by the device. The write community name may be omitted, the driver uses the read community name for both, read and write in this case. If both community names are missing, the driver uses 'public' as a default for read and write community.

• timeThreshold --- Defines the limit in nanoseconds, for the XLi clocks accumulated time error

• timeoutDelay --- Defines the delay time for exceeding the timeThreshold before generating a time error alarm

• poweronAlarm --- Defines the time after a power on cycle, for how long F73 alarms are suppressed.
