Possible Attachments
The OSM BC08 allows you to connect up to 8 DTEs or network components over
FO ports and is suitable particularly in environments in which the data lines run
through areas with high levels of electromagnetic interference (for example, in the
vicinity of power supply cables).
The OSM BC08 can be coupled with other OSM BC08, OSM ITP62, OSM TP62,
OSM TP22, and OSM ITP53 over the optical ports 7 and 8 to form a redundant
fiber-optic ring, a fiber-optic star, or a fiber-optic linear bus.
The OSM BC08 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
OSM. The use of these functions is described in the OSM/ESM Network
Management User Manual /1/.
