1.1.4 ESM ITP80
Possible Attachments
The ESM ITP80 allows attachment of up to eight DTEs or network segments with
ITP connectors (sub-D9 female). By coupling further ESMs to ports 7 and 8 it is
possible to create optical bus and ring structures.
The ESM ITP80 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 these functions is described in the OSM/ESM Network
Management User Manual /1/.
