Evolution Manager

General DescriptionThe Evolution Manager is a web interface of the Network Element. It is used for configuration, testing and monitoring of the Network Element. The Evolution Manager can be accessed froma web browser, or by means of a network element management system, such as NetMaster.

The Evolution Manager has two main navigation elements, the top menu and the equipment view. The content frame will display information as a result of the selections in both menus. Thisallows for filtering the information in the content frame, by selecting a specific unit in the equipment view. The Evolution Manager has two navigation modes:

Network Element:When no units are selected in the equipment view, selections in the top menu will cause information relevant to the Network Element as a whole to be displayed in the content frame. Thenavigation status will read Network Element, and the Evolution Manager is said to be in Network Element mode.

Individual Unit:In contrast, when a specific unit has been selected in the equipment view, selections in the top menu will cause information only relevant to the selected unit to be displayed in the contentframe. This mode is called Individual Unit mode, and the navigation status will reflect this by displaying the name of the selected unit.

In order to break out of Individual Unit mode, the Home menu option must be selected from the top menu. This brings the Evolution Manager back to Network Element mode, and thiswill be reflected in the navigation status.

Graphical User Interface (GUI)A schematic view of the GUI is shown in the figure below:

Radio Protection SwitchingRadio Protection Switching (RPS) operations for N+1and Hot Stand-by systems are managed by the Supervisory Unit This RPS module interacts with other system hardware resources to achieveautomatic protection switch operations based on switch criteria inputs from the individual radio channels.

Switch Configuration (Freq. Div.)

1+1 FD protection switchingAn automatic switch procedure is initiated on the receive side based on a set of switch criteria acquired from the hardware resources. Aligned switching will be performed if possible.The active channel which is to be protected, is polled for data alignment status. When the data stream from the protector demodulator is aligned with thedata stream from the active channel demodulator, an errorless switchover is performed. In case the alignment process fails, a forced switchover may be performed dependent upon active criteria and configuration settings for the RPS system (if a continuity criterion is active initially the RPSwill not check for alignment but immediately select the forced switchover option) When the criteria for protecting the channel are no longer active the channel will be restored if the RPS is set to revertive mode.

RPS, Hot Stand-bySet up and configuration of Hot Stand-by systems. Click on the different sub pages in the screenshot below ("Switch Configuration" or "Switch Channel Status") for more information.

Switch Configuration (Hot Stby)Hot Standby implements equipment protection for a radio hop. A protection switch section is comprised of the duplicated transmit- and receive-equipment required to serve oneantenna. This switch section is monitored and controlled by a single RPS module. The two equipment paths are identified as Ch. 1 and Ch. 2. The protection switch state iseither "Ch. 1 active" or "Ch. 2 active". Each traffic direction (transmit and receive) has its own set of switch criteria. The system may be set up as "Unidirectional" or "Bi-directional". Bi-directionalBi-directional means that the switching in Tx and Rx directions will follow each other. Uni-directionalUni-directional means that the two traffic directions for a switching section are controlled individually and independent of each other (treated as two independent switch sections). Typical 1+1 HSB switch scenario (bidirectional)

If Tx criteria are activated the RPS controls the mute/unmute functions on the two transceivers accordingly. The RPS is to protect the Rx direction for that same channel,as long as the channel is free of errors.If the RPS detects an Rx criterion, it shall protect the associated channel, and revert back to bidirectional mode when th Rx criterion disappears. Switch on Tx side will notbe performed.If there are active Rx criteria on both Rx channels the most severe criterion is to be acknowledged. This means that the automatic HSB switch actually operates inunidirectional mode as long as conflicting criteria are active. When there are no longer conflicts between Tx and Rx criteria the switch state should be changed tobidirectional

Typical 1+1 HSB switch scenario (unidirectional)

The RPS controls the Rx switch based on Rx criteria information as for a 1+1 FD automatic switch.If Tx criteria is activated the RPS controls the mute/unmute functions on the two transceivers accordingly.

Manual RequestsThe responsibility of the manual switch function is to set the requested worker channel in standby state in both traffic directions by sending mute/unmute commands to thetranceivers and performing an Rx switch Hot Standby with Dual BasebandRegarding protection on Rx side there is one exception to the description above:If the "HSB Dual Baseband" option for HSB systems is specified, the RPS will refrain from doing any Rx switching. In this case the external equipment (mux) will duplicate theline traffic input onto two input ports, and the RR equipment will duplicate the RF signal onto two Rx branches (receiver-demodulator-baseband) and make both data streamsavailable on the two output ports. The RPS will only switch on the Tx side. Manual SwitchManual switch/restore requests are considered local to the station and, for a given antenna direction, involves transceiver RF switch for Tx and baseband alignment switch forRx. This operation is implemented as a bidirectional locked switch.

Note! If an IFU is removed and reinserted (e.g. for maintenance reasons), the SU must be cold started afterwards to ensure that correct RPS system state is achieved.

N+1 Frequency Diversity, Section Config

N+1 FD protection switchingAn automatic switch procedure is initiated on the receive side based on a set of switch criteria acquired from the hardware resources. Aligned switching will be performed if possible.The active channel which is to be protected, is polled for data alignment status. When the data stream from the protector demodulator is alignedwith the data stream from the active channel demodulator, an errorless switchover is performed.

Alternatives: Revertive modeAn active channel using protection will be restored upon deassertion ofall criteria This should be the default mode of operation.

Non-Revertive modeAn active channel using protection will continue to be in protected stateeven if all criteria are deasserted, until another active channel needsprotection or the protecting channel becomes degraded, in which casea restore operation is performed.

Remote TX Bridge This property defines the state of the remote TX bridge when no regular channel isusing the protection channel. The channel bridged on TX side will achieve the sameprotection switch performance as it would in a 1+1 system (shorter switch operationtime).

Mode: (always revertive and Ch. P if LPT is enabled or auto).Revertive: When no channel requires protection the TX bridge will revert tothe channel specified by the Revert to Ch property (this channels trafficwill be duplicated on the protection channel).

Non-revertive: The regular channel which most recently has beenprotected keeps its bridge on TX side (the TX bridge is left unchanged whenthe channel reverts to its regular state at RX side). This enables preparedswitching of the channel most recently protected as long as no otherchannel needs to be protected.

Revert to Channel In revertive mode it controls which channel to be bridged on TX side while no switchrequests exist. Unavailable in non-revertive mode.

High Priority Channel If a channel is selected as High Priority Channel it will have an associated IntrusionLimit which defines the degradation at which this channel always is givenprotection, no matter what conditions may exist on any other regular channel.

The configuration must have been uploaded from the replaced SU, using the configuration upload feature under theMiscellaneous tab. The configuration from the replaced SU will be downloaded to the new SU. In addition the licenses from the replaced SU will be temporary enabled for a maximum period of 90 days in addition to anyexisting licenses on the new SU. These temporary licenses can be used while ordering new license keys from Nera.

SU Software VersionsWhen new software is downloaded to the element it will initially be set in inactive state (Active no). Click the "Switch software" button to swap the Software Package. The system will perform a warm start when software is swapped.

Note! If only one software package is present on the Network Element, only one table will be visible in "Overview" in the screenshot above. Function Buttons: Switch Software

Reset Software

Swap between the two available software packages.

Performs a warm reset of the NE software

Note! Bit error may occur when software packages are switched.

Note! It is recommended that you clear the file cache in your web browser after a software switch. The reason for this is to make sure that the browser receives the correct files. Complete stateIf all the required files are present and the checksum is OK, the software package is in Complete state.Compatible stateEach software package contain a list of hardware compatibility requirements. This consists of a list of hardware modules with an accompanying version range. If all the detected modules in the systemare found in this list, and their versions fall within the specified ranges, the software package is compatible.

Software DownloadA software release generally consists of several ".tar" files. When a new software version is downloaded to the NE, it is recommended to start with the ".tar" file with the lowest number (e.g. "SW-EVOULUTION-APP-R1A00_1.tar" and then "SW-EVOULUTION-APP-R1A00_2.tar" etc). Follow the instructions on the screen. If there is an inactive software package on the NE already, this software package will be overwritten. Dependent on the system configuration it is not always necessary to download all ".tar" files in the actual software release. After downloading the first file, you will be prompted for the next file todownload, if required. When all required files are downloaded, the following message will be displayed: The software was downloaded successfully and is now in complete state. The downloaded software is still inactive. Activation of new software is performed from the "Software Versions" page.

SNMPSimple Network Management Protocol (SNMP) is an application layer protocol that facilitates the exchange of management information between network devices. SNMP enables networkadministrators to manage network performance and find and solve network problems.SNMP is a simple request/response protocol. The network-management system issues a request, and managed devices return responses.

Note! If the Ethernet ports are forced down due to signal loss (LLF enabled), application of a traffic loop on one of the NEs may result in unwanted activation of the Ethernet ports on the NE inquestion as well as on the corresponding NE. If it is required that the Ethernet ports stay disabled, the ports must be manually disabled on the NEs or on the periferal equipment.

Note! Link Loss Forwarding must be enabled on both corresponding Network Elements In the figure below, an Ethernet link loss will be detected on NE2. A LLF signal will be sent to NE1 and the Ethernet port will be shut down.

In the figure below, a loss of signal will be detected on both Network Elements and the Ethernet ports will be shut down.

The LLF function is specially useful in ring protected systems. In the example below, a cable is broken between Router B and NE2. Link Loss failure will be detected on NE1 and transmission shut down.The Ethernet traffic between Router A and B will be routed via NE3 and NE4.

Link Loss Forwarding (LLF)With this function enabled, a loss of signal on one Network Element (e.g. cable failure/unplugged) will be detected on the corresponding Network Element and shut down this Ethernet port.
