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 colocated 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.

Features

• Cost-effective solution for management of devices in all locations (large headend to small hubs/OTN)

• Manages Scientific-Atlanta and third-party equipment via proprietary protocol, SNMP, or contact closures

• Translates proprietary protocols to SNMP and passes configuration/alarm information to network managers

• Highly reliable (no fans, no hard drive) hardware and software solution

• Alarm notification with Email, Pager or SMS

• Easy to use, intuitive Web browser interface

• Provides easy integration with multiple client options – Web browser, TNCS, ROSA NMS, 3

• Open standards based interfaces (SNMP, HTTP, FTP, HMS, DateTime, etc.)

• Delivered with software already installed

• Software can be upgraded remotely over LAN/WAN

• Automatic remote backup and restore to save the entire configuration of the ROSA EM

• Seamless integration into currently installed TNCS and ROSA systems

• Dual temperature probes available as option

• 2 RU, 19-inch rack-mount chassis

The southbound management interfaces are designed to communicate with the managed devices and consist of:

• Multiple serial ports (RS-232, RS-485, RS-422)

• Digital and analog I/O contact closures interface

• SNMP Manager

• Temperature probes

• Network interface card

Flexible Client Options

There are four fundamental client options available for the ROSA EM; a simple Web browser, TNCS client, ROSA NMS client and third party Network Management Systems each designed to meet specific needs of the user. ROSA EM can be configured to do as much or as little as required to meet the needs of the technicians and engineers charged with managing the broadband network.

• Simple Web Browser – The user

will open a Web browser window for each ROSA EM site. This is an ideal application for small systems that have only one or two sites with ROSA EM installed.

• TNCS Client – The TNCS client will

aggregate all of the ROSA EM sites to produce a single network view that is easy to understand. In addition, TNCS will aggregate the alarms, perform multi-site backup schemes and retain historical logs for alarms, system executables, and software status for all of the ROSA EM sites.

• ROSA NMS Client – A ROSA client

provides all of the TNCS functionality as well as a relational database that enables the operator to produce performance and trending reports on the network, the managed devices, and overall system performance. ROSA also has several modular advanced tasks that provide significant added value to system operators, engineers and managers.

• Third-Party Client – ROSA EM is ideally suited to integrate into an overall 3

northbound SNMP interface in ROSA EM supports Traps, Gets and Sets allowing the overall NMS to have control of the managed devices. Launching the Web browser in ROSA EM allows the NMS operator to easily view the details of any managed device from the operations center.

Network Elements

The northbound management interfaces are composed of:

• Web browser client interface on the ROSA EM that allows management of network devices as well as viewing real-time status and alarms.

• The SNMP agent in ROSA EM provides a northbound SNMP interface to higher level Network Management Systems (supports TRAPS, GETS and SETS).

• Utilizes FTP to remotely upgrade ROSA EM software as well as the backup and restoration of ROSA EM configuration data.

(*) Note concerning Safety Extra-Low Voltage (SELV) Circuit Warning

To avoid electric shock and in order to comply with the product’s regulatory safety compliance certifications:

• Do not connect any I/O, signal or communication port to circuits falling beyond the requirements for SELV circuits

• Always verify voltage, current and energy levels of connected circuits against SELV requirements (for a full definition of SELV

requirements, refer to UL, EN or IEC 60950 standards for limit values).

• Ensure that only ‘Digital Input Ports’, Galvanic Isolated Digital Input Ports’ or ‘Relay Outputs’ are connected to outdoor circuits.

Important:

• SELV voltage limits for indoor connections are < 60 V DC (or peak) or < 42.4 V AC RMS.

• SELV voltage limits for outdoor connections are lower than those for indoor connections.

• Outdoor voltages should be no greater than 15 Vrms, 21.2 Vpk, and 30 V DC under normal operating conditions.

• Cabling of outdoor circuits must be shorter than 140 feet or 42 meters.

• In all cases it is needed to protect outdoor cabling by means of a Primary Surge Protector at the position where the wiring enters the

building.

• Outdoor cabling should be routed away and spaced with adequate clearances from power and lighting conductors.

• For installations in the United States, refer to the appropriate sections in the National Electrical Code (NEC).

• For installations in other countries, ensure that the installation complies with the National requirements taking in account the above-

mentioned recommendations.
