1.1.9 ESM TP40
Possible Attachments
The ESM TP40 allows attachment of up to 4 DTEs or network segments with TP
connectors (RJ-45 jack). By coupling further ESMs via ports 3 and 4 it is possible
to create bus and ring structures.
The ESM TP40 also has four digital inputs. The states of the inputs are available
in a management information base (MIB) and can be read using 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
ESM. The use of these functions is described in the OSM/ESM Network
Management User Manual /1/.
