1.1.8 OSM TP22
Possible Attachments
The OSM TP22 allows attachment of up to 2 DTEs or network segments with TP
connectors. By coupling an OSM via ports 3 and 4 it is possible to create optical
bus and ring structures. The OSM TP22 can be coupled with other OSM TP22,
OSM TP62, OSM ITP53, OSM ITP62, and OSM BC08 modules via the optical
ports.
The OSM TP22 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
OSM. The use of these functions is described in the OSM/ESM Network
Management User Manual /1/.
