Element Manager (EM) is specifically designed to cost effectively
monitor and control the transmission network of headends, hub sites, HFC outside
plants, and transmitter sites. This unit manages the equipment that is co-located at the
site where the ROSA EM resides, whether this equipment has an SNMP, serial (RS-
232/422/485), or contact closure interface.

– Element Management System
The ROSA EM is a polling engine that actively polls all of the devices that it manages looking for problems. In the
event a problem is detected, ROSA EM will send alarm notifications to the appropriate personnel via SNMP trap,
Email, Pager, or SMS. ROSA EM communicates with the managed devices via proprietary protocols or contact
closures, then translates this information to SNMP, which can be passed to a higher level network management
system. When ROSA EM is configured to perform backup protection, it will automatically initiate pre-defined
backup schemes that reroutes signals, activates, and configures standby devices, all within seconds of a device
failure. ROSA EM is fully integrated on the ROSA Network Management (NMS) and ROSA Video Service
Management (VSM) systems.
The main functions of the ROSA EM are to:
●
Automatically backup failed devices
●
Monitor the health of the transmission network
●
Act as an SNMP proxy
●
Send alarm notifications when a problem occurs
●
Perform local automation tasks
The ROSA EM is a 2 RU high, 19-inch rack-mount embedded platform that operates without a monitor or
keyboard. The operator uses a standard web interface with the ROSA EM via a simple easy-to-use GUI.
Communication to the ROSA EM can be established over any LAN/WAN network that supports Ethernet. In
addition, dial-in and dial-out (e.g., ISDN) is supported for cases where only a switched connection is available.
