6345-50 Training Presentation6345-50 EM Commissioning a NE.ppt6345-50 Training Presentation6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationThis presentation takes you through the commisioning of the Tellabs 6345 and 6350 Switch Nodes.6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationThe purpose of commissioning an 6345/50 NE is to create a model of the NE. This model allows you to manage (control and monitor) the NE from the Network Manager and Craft Terminal.Before you start commissioning a 6345/50 that is to be taken into service, you must make sure that the following tasks have been performed: The subracks and cables (Ethernet, Alarm and Power) have been installed. The modules have been installed in the correct slot positions. A hierarchy has been defined in the Network Manager in which the new NE is to be placed6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationThe Tellabs 63xx managed access equipment utilises the OSI network protocol for communication between the management system and the network. The NSAP address (Network Service Access Point) is a unique address used to identify each NE.Tellabs 6345/50 NEs are assigned the default NSAP address 49000101 during production.The Area Address 490001 and the Selector Field part 01 of the address are always the same. The System/Node ID is the NEs Ethernet Address (also known as MAC address). Each master module is given its own unique Ethernet address in the factory, which is printed on the main board label on the front of the CMCC module. The first 3 bytes (00 A0 82) denote Tellabs Denmark equipment, and the following 3 bytes are unique to the specific piece of equipment.The NSAP address can be changed, but it must fulfil certain requirements. For example, addresses starting with 49 can be used for private networks, and with 39 must be allocated by the ISO organizations. As the 6345/50 only supports IS-IS level 1 routing, 6345/50s that have different area addresses will not be able to communicate with one another. So, if the NSAP address is changed then the NE and many other NEs may be unreachable from the management centre. Also, if two NEs have the same NSAP address it will not be possible to communicate with them.Note A new NSAP address does not replace the old NSAP address until a Reset NE procedure is performed.6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationThe Craft Terminal for the Tellabs 6345/50 is called 6300 Craft terminal.

This is a service terminal used mainly by technicians when installation/commissioning the 6345/50. The Craft Terminal runs on a Windows 2000 platform and the user-interface is started either by using an icon on the desktop or directly via the PCs start button.The CT users a suite of graphical user interfaces to enable you to easily operate the 6345/50. These GUIs are identical to those found on the 6300 network manager.6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationCommissioning the 6345/50 can equally well be carried out from the 6300 network manager.This is done via the Equipment View dialogue, that can be started either from the Network Editor or the Network Management windows. 6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationTo be able to manage an NE, you have to create a model of the actual physical equipment. You can create the model automatically by transferring information directly from the actual equipment or you can create the model manually. The model is stored in the NE itself. Typically, you will create the initial model of a new NE automatically and then, when adding or removing equipment from the NE, make the changes to the model manually. You can see a representation of the actual modules present in the NE as well as the corresponding model of the NE equipment in the Equipment Commissioning window in Element Manager and Craft Terminal. It is in this window that you create the model (automatically or manually).An NE in a network which is managed by a Management System, is constantly monitored for discrepancies. If the actual equipment of the NE differs from the NE model (usually called the expected equipment), then the NE is un-manageable and an alarm is sent to the management centre indicating the corresponding fault.6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationAn NE model can be created automatically by transferring information directly from the actual equipment. This can be done using the Copy Actual to Expected Wizard. Start the Wizard by pressing the Copy Actual to Expected button in the Equipment Commissioning window.The Wizard guides the user through the operation of assigning values for the subrack and module usage.Use the Wizard only when doing the initial commissioning of the node. When adding or removing modules, use the methods described later in the material because you may get bit errors in the existing modules when using the Wizard.6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationRight-click in the Network Element title bar and select Copy Actual to Expected. The Copy Actual to Expected Wizard appears.

Assign a usage to modules marked with a blue question mark (?) by:a) Double-click on the module, or, alternatively press the spacebar when the cursor is on it.b) Select the relevant value for the Module Usage attribute in the window that appears.c) Click OK.

Note: The Module Usage attribute of all other modules marked with a green check mark may be changed using the same procedure.

6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationTo configure an NE manually you can use a number of single operations. 1- Insert an Expected Rack in the NE2- Insert an Expected Subrack in an Expected Rack of the NE3- Insert an Expected Module in an Expected Subrack of the NE

This method should be used when adding or removing modules to an NE which already is in service. In which case only step 3 is applicable. Note that if you instead use the automatic configuration tool (the Copy Actual to Expected Wizard) you may get bit errors in the existing modules.6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationAny module executing SW has a default configuration that puts the module in a well-defined state if no other configuration has been imposed on the module. An actual, but not expected module, will use its default configuration. The default configuration is determined by the SW, so only when the SW has been successfully booted, the module is able to use the default configuration (or the management system defined configuration for that matter). 6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationTo avoid generation of the equipment alarm Unit main type mismatch (by the managed object class called Slot), you must first remove the expected module from the NE in the Equipment View window and then remove the module from the physical NE.

6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationThe physical medium for management traffic is via Ethernet, RS-232 or via the embedded control channel DCCR/M. The procedures for configuring ECC is reasonably comprehensive and is therefore covered in a later course module

The choice of DCCR or DCCM as physical medium for ECC will survive a reset to default, but will not survive a reset to factory settings.

Note. The default embedded control channel configuration for a traffic module is no ECC management.

6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationThe Tellabs 6345/50 system is classified as a Class 1 laser product in accordance with IEC 825, so exposure to hazardous laser radiation is impossible during normal operation and maintenance. When the system has been installed, the laser radiation is effectively enclosed in the optical fibre path between optical modules at each end. The applied lasers are embedded 1300 or 1550 nm wavelength semiconductor lasers. 6345/50 equipment is configured per default, so that in case of an interruption of the optical fibre path by accident (e.g. cable rupture) an automatic safety mechanism will result in a periodic shutdown of the transmitter laser. Hence, the laser radiation from any fibre end is restricted to a 2-second period, which is repeated every 70 seconds. With less than 0 dBm (L-1.1 and L-1.2) radiated optical power during the 2-second period, the time averaged power is less than 15 dBm, which is harmless at relevant wavelengths. Exposure to laser radiation risked during service or installation can be hazardous in case of double fault conditions. 6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationPort Mode determines whether alarms from a termination point are reported to the management centre. If Port Mode is set to Automatic, alarms from the termination point will not be reported until a signal is received. When a signal is received Port Mode automatically changes to Monitored. Generate Alarms enables the selection of Remote Defect Indication (+ also Signal Server Failure for VC4s). MS Exc Def. Cons. Action Enable determines whether an AIS is issued when the MS Signal threshold on the received signal is crossed. The threshold is set to BER of 10-3. The Disable Synchronization Status Message attribute is shown for STM- ports. It determines whether the quality level indicated in the SSM of STM- signals is transmitted as it is, or whether it is overwritten with the quality level QL-DNU (Do Not Use). A 16 character* Trail Trace Identifier (TTI) can be sent, and a Received TTI monitored. Detect Mismatch enables alarm generation if a TTI mismatch (i.e Received TTI Expected TTI). Enable TIM Consequent Action inserts AIS if a TTI mismatch is generated. *If not all 16 characters are used, then the system will insert NULL for the unused characters (padding).6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationThe synchronization of the network element can be derived from a number of sources, both from traffic inputs and station clocks.The procedures for selecting and configuring timing inputs is reasonably comprehensive and is therefore covered in a later course module.

6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationNE Identification A name and location label. It consists of information about the location of the NE. It is possible to set the address, location, floor, row of racks, etc. For example in the: NE Name: 6350_1_LondonSW1 NE Location: 96 Main Street, Wimbledon Note: A maximum of 64 Latin1 characters can be entered in each label field. NE Address A globally unique address, the NSAP address, which makes it possible for the management software to communicate directly with, and therefore manage, the NE in question.Change Password The password provides additional access security to the NE (in addition to the NSAP Address). The password is required when connecting to the NE with craft terminal or when using the Network Manager. During production 6345/50 CMCC modules are not assigned a default password. Therefore when you first communicate with an 6345/50 network element, you do not need to enter anything in Enter Password field. User Labels User-defined labels to identify the NE's hardware and software components. This helps you to keep a track of versions of software.6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationYou are allowed to assign your own text labels to parts of the NEs - making it easier for you to identify a specific point in an NE.You can assign user labels for the: NE name and NE location Rack All modules, both software and hardware labels Each connector on traffic modules OHA channels EOW and User Channels Fan trays

Tip: The shortcut to a label is L. Select the item in question and press L6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationIn a telecommunications network it is important that the NE clock in every managed NE is synchronized, so that when alarms are reported to a management centre, the times are absolute, not relative to the local time. The sequence of a chain of events (alarms) can then more easily be interpreted. Universal time coordinated (UTC time) is the time read on a clock situated at 0 longitude (Greenwich, England). UTC time was originally known as Greenwich Mean Time (GMT time). Synchronizing with PC time: If your telecommunications network operates in more than one time zone, or you are connected to another telecommunications network operating in another time zone, then it is advisable to synchronize your NE clocks by using this option. All personal computers have clocks that are synchronized with UTC time. Therefore, by synchronizing all NE clocks with PC time you can synchronize them with UTC time. Synchronizing with User time: If your telecommunications network is a purely local network (it operates in only one time zone) and has no connections to other telecommunications networks operating in other time zones, then you can use this option so that all NEs in your network are synchronized with local time - which is the same for all NEs. The System Date and Time is automatically adjusted by 6300NM.6345-50 EM Commissioning a NE.ppt6345-50 Training PresentationIf the TP4 connection between a management system and a network element is broken or the cable is removed from the F-interface, the management system must supply the password again.

Note. The NE password is also stored in the management system. So, if you change the NE Password from the 6300, it will still possible to make a connection to the NE. However, if another management system tries to connect to the NE it will be prompted for the new password.6345-50 EM Commissioning a NE.ppt6345-50 Training Presentation6345-50 EM Commissioning a NE.ppt
