4.1.8Digital Inputs

In the case of the OSMs/ESMs with digital inputs, the states of these inputs are available in a management information base (MIB) and can be read with an SNMP get request. Depending on the configuration of the device, changes at these inputs can also trigger the sending of E-mails, SNMP traps and/or entries in the log of the OSM/ESM. The use of these functions is described in the OSM/ESM Network Management User Manual /1/.

The digital inputs are attached using six-pin plug-in terminal blocks with screw locking mechanisms.
