1.1.6 ESM TP80
Possible Attachments
The ESM TP80 allows attachment of up to 8 DTEs or network segments with TP
connectors (RJ-45 jack). By linking further ESMs to ports 7 and 8 of the ESM TP80
it is possible to create bus and ring structures.
The ESM TP80 also has eight 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 this function is described in the OSM/ESM Network Management
User Manual /1/.
