As of version 3.1.610 the sat-nms MNC provides an universal SNMP agent which publishes a limited number of device parameters in a fixed, table oriented MIB. This SNMP agent permits to monitor and partially control any sat-nms MNC using the same MIB - regardless of the device configuration of the particular MNC.
The MIB provides one table which contains all devices which are configured in the sat-nms MNC. No special mapping is necessary for this table as there are only very common parameters like the device name, its fault state or its administrative state in this table.
Beside this, the MIB contains a couple of tables, each representing all devices belonging to a so called device class. For instance, there is one table containing all HPAs in the MNC and one table containing all waveguide switches. These class specific tables contain some parameters which are common to the devices of the particular class. The HPA table contains parameters for tx-on, for attenuation and forthe measured output power for each device, the waveguide switch table provides a parameter for the switch position.
As device drivers sometimes use different parameter names for the same or similar function, an individual mapping from the universal parameter in the MIB to the real parameter in the device is necessary for every single sat-nms device driver. Device drivers which do not contain any information about the device class this device belongs to and how the parameters are to be mapped into the MIB only appear in the in the general device table of the MIB.
A sat-nms device (physical or logical) may be represented by multiple device classes in the MIB or by multiple instances of the same class. For example a combined upconverter and HPA may appera as a HPA in this table (with its HPA specific parameters) and a second time in the upconverter table with its frequency parameter.
Also devices consisting of multiple modules can be treated this way in the MIB, there are quad block upconverter on the market which provide four independent converter modules in one device. Such a device can be mapped in way, that it appears as four BUC devices in that table.
