Network Management
ROSA™ EM - Element Management System
Description
™
The ROSA Element Manager (EM) is specifically designed
to cost effectively monitor and control the transmission
network of headends, hub sites and HFC outside plants, and
transmitter sites. This unit manages the equipment that is co-
located on the site where the ROSA EM resides, whether this
equipment has an SNMP, serial (RS-232/422/485) or contact
closure interface.
The main functions of the ROSA EM are to:
•
Monitor the health of the transmission network
•
Act as an SNMP proxy
•
Send alarm notifications when a problem occurs
•
Automatically backup failed devices
•
Perform local automation tasks
The ROSA EM supports several hundred Scientific-Atlanta and third-party devices. Support for new devices is
continuously being added to the ROSA EM, which can be exported to existing installations with a simple software
upgrade.
The ROSA EM actively polls all of the devices that it manages looking for problems and 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 their 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.
The ROSA EM is a 2 RU high, 19-inch rack-mount embedded platform that operates without a monitor or
keyboard. The operator interfaces with the ROSA EM via a simple easy-to-use and understand Web browser
client. 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.
