Description 1 Introduction 1.1 Purpose and scope The purpose of this document is to describe and give a general overview of the products in the OMT product family. The products are OMT, Remote OMT and Remote OMT over IP. This version of the product description contains functionality up to BSS release R12.1. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 4 (29) OMT Product Description 2 Product overview 2.1 General All products in the OMT product family contain functionality for configuration and fault localization of RBS 2000 base stations. The functionality is needed for RBS 2000 configuration and greatly simplifies the work at RBS 2000 fault localization. The OMT products have the same functionality. The only difference between the products is where you connect the product for communication with an RBS 2000. OMT is connected to the OMT port on the RBS 2000. Remote OMT is connected to an ETC4 or ETC5 device on a BSC. Remote OMT over IP is connected to a TCP/IP network, to which BSCs also are connected.

The OMT is installed on a standard PC, i.e. no extra HW is required for the OMT. It is connected to the OMT port on an RBS 2000 for communication with the RBS. The OMT contributes with: 2.3 • The time for configuration and installation of an RBS is minimized. • The time for fault localization is minimized. • Minimizing user mistakes on site during site configuration. Remote OMT Remote OMT makes it possible to perform operation & maintenance for RBS 2000 base stations from BSC site. The Remote OMT is used as a complement to the OMT. The Remote OMT is installed on a PC, with an extra card called Thor-2. Remote OMT is connected to an E1 or T1 interface on a BSC for communication with an RBS. One dedicated timeslot is used for the communication between Remote OMT and RBS. The Remote OMT makes it possible to: 2.4 • Retrieve detailed information about an RBS 2000 remotely from a BSC site. • Perform fault localization of an RBS 2000 remotely from a TCP/IP network connecting BSCs. This means that it will be easier to prepare for a site visit and it will be possible for experts to remotely guide service personnel at site. • Perform "hardware reset" of an RBS 2000 remotely from a BSC site. Remote OMT over IP Remote OMT over IP makes it possible to perform operation & maintenance for RBS 2000 base stations from anywhere on a TCP/IP network connecting the operators BSCs. The Remote OMT over IP is used as a complement to the OMT. The Remote OMT over IP is installed on a PC, with a network board (Ethernet board). Remote OMT over IP is connected to the TCP/IP network that connects the operators BSCs. The communication between Remote OMT and RBS shares timeslot or part of timeslot with SO CF. Remote OMT over IP makes it possible to: 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 6 (29) OMT Product Description • Retrieve detailed information about an RBS 2000 remotely from a TCP/IP network connecting BSCs. • Perform fault localization of an RBS 2000 remotely from a TCP/IP network connecting BSCs. This means that it will be easier to prepare for a site visit and it will be possible for experts to remotely guide service personnel at site. • Perform "hardware reset" of an RBS 2000 remotely from a TCP/IP network connecting BSCs. Benefits with Remote OMT over IP compared to Remote OMT: • A whole time slot does not have to be allocated for OMT signaling. The signaling is embedded in the LAPD signaling. • It is much easier to establish a connection for the OMT signaling because it is not needed to set up a path in the transmission network. Access to an IP network is the only thing that is needed. • OMT functionality can be performed from many remote sites (from anywhere with a TCP/IP connection). 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 7 (29) OMT Product Description 3 Functionality 3.1 General Functions are initialized by selection in the graphical user interface. Some functions contain communication between OMT and RBS, while other functions don’t. Functionality without OMT-RBS communication can be used without a connection to an RBS. This makes it possible to prepare a site visit and analyze output after the site visit. This means reduced time spend on site. 3.2 Graphical user interface 3.2.1 General The graphical user interface consists of: • Main window with - menus - a left pane dedicated for views - a right pane dedicated for display windows - a toolbar with most frequently used functions - a status bar. • Different views of the managed RBS 2000 configuration. Each view contains selectable objects. Only one view is displayed at the same time. • Display windows that give the user information about the managed RBS 2000 configuration. Most of these windows are displayed in the right pane of the main window. The display windows that are not display there are display as Notepad windows. • Dialog windows that are displayed when the OMT needs input from the OMT user. These windows are displayed on top of the Main window. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 8 (29) OMT Product Description Figure 2 Main window and system view The graphical user interface allows the user to work either object oriented or function oriented. Object oriented way of working means that an object in a view is selected and after that a function is chosen for the selected object. Function oriented way of working means that a function is selected in the main window menu and after that an object is chosen. The object-oriented way of working and the toolbar makes it possible for the user to work quickly. The function-oriented way of working makes it easy to find functions. 3.2.2 System view The system view give the user a mean to access objects that represents high level system functions, such as the RBS and the IDB. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 9 (29) OMT Product Description 3.2.3 Cabinet view The cabinet view helps the user to localize the position of RUs in the RBS. It also gives accessibility to a number of RUs. Frequency band for TRUs and CDUs is indicated in the view. The cabinet view is also useful when verifying that the IDB describes the RBS. When using Remote OMT or Remote OMT over IP, the cabinet view can give the user a feeling of security that the user is connected to the correct RBS. Figure 3: Cabinet view for RBS 2106 3.2.4 Radio view The radio view gives the user a view of the radio transmission paths of the RBS. It also gives accessibility to radio related RUs. Frequency band for TRUs and CDUs is indicated in the view. It’s possible to enable indication of faulty RUs in the view. Faulty RUs are marked with red color. This is very useful when performing fault localization of passive RUs, such as cables, since passive RUs don’t have any fault LED. The radio view is also very useful when verifying that the IDB describes the RBS. When using Remote OMT or Remote OMT over IP, the radio view can give the user a feeling of security that the user is connected to the correct RBS. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 10 (29) OMT Product Description Figure 4 Radio view 3.2.5 Object view The object view is a Windows Explorer look-a-like view with all OMT objects in a hierarchical list. It gives the user a possibility to browse around, sort and select any object. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 11 (29) OMT Product Description Figure 5 Object view 3.3 RBS communication 3.3.1 General To enable functions with OMT-RBS communication a communication link must be established. The communication link is established in different ways for the different OMT products. The transmission speed (bandwidth) also differs between the OMT products. 3.3.2 OMT A communication link between OMT and an RBS is very easily established by 1) Physically connect the OMT PC with the OMT port on the RBS using an OMT cable. 2) Selecting the connect function in OMT GUI. No parameter has to be entered. The transmission speed, on the link, is 115.2 kbit/s. This enables fast OMT functions. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 12 (29) OMT Product Description 3.3.3 Remote OMT A communication link between Remote OMT and an RBS is established by 1) Physically connect the Remote OMT PC with an ETC4 or ETC5 device on the BSC that controls the RBS using a Remote OMT cable. 2) Setting up a semi-permanent connection in the BSC and allocating an Abis timeslot for Remote OMT signaling. This is done by enter MML commands in the BSC. See the OPI for Remote OMT. 3) Selecting the connect function in Remote OMT GUI. A timeslot and a TEI value are entered in the OMT GUI. The transmission speed, on the link, is 64 kbit/s. 3.3.4 Remote OMT over IP A communication link between Remote OMT over IP and an RBS is established by 1) Physically connect the Remote OMT over IP PC to the TCP/IP network that connects the operators BSCs using a Remote OMT over IP cable. 2) Enable the Remote OMT over IP feature in the BSC and open the BSC for a Remote OMT over IP client. This is done by enter MML commands in the BSC. See the OPI for Remote OMT over IP. 3) Selecting the connect function in Remote OMT over IP GUI. An IP address and a TG identity value are entered in the OMT GUI. The transmission speed, on the link, is 8-64 kbit/s dependent on how the Remote OMT over IP timeslot is configured from the BSC. 3.3.5 Data sent between OMT and RBS To make OMT functions fast and to reduce the risk that Remote OMT over IP signaling disturbs OML and RSL signaling transferred data is compressed for functions that send a lot of data. One example is the IDB that’s transferred when using the Read IDB and Install IDB functions. Another example is the RBS log that’s transferred when using the Display RBS log function. 3.4 RBS configuration 3.4.1 General To configure an RBS 2000 the OMT is needed. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 13 (29) OMT Product Description When configuring an RBS the OMT user describes the RBS and how it shall be used and then sends the description to the RBS. The RBS stores the description in persistent memory. The description of the RBS and how it shall be used is called IDB (Installation Data Base). An IDB is created with the OMT function “Create IDB”. The created IDB contains default values for changeable configuration parameters. If needed, these default values are changed to correct values with “Define” functions. The IDB is sent to the RBS with the OMT function “Install IDB”. 3.4.2 Create an IDB Values for the following parameters are chosen when creating an IDB with the function “Create IDB”: • Transmission interface type • For each cabinet: - Cabinet type - Power system - Climate system • For each antenna sector: - Frequency - CDU type - Presence of duplexer - Presence of TMA - TX combining/RX sharing configuration - Number of TRXs per antenna sector Values for the parameters above are chosen in option boxes in different Create IDB windows. In each of these windows they are chosen in the order from top to bottom of the window. When selecting a parameter value, selectable values for the parameter below are filtered so only valid values can be selected. This reduces the number of selectable parameter values, which makes it easier to select correct value. About 50.000 different IDBs can be created with the OMT. 3.4.3 Update the IDB The following parameters can be changed using “Define” functions: 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 14 (29) OMT Product Description ! Transmission parameters The transmission is described by entering values for following parameters: - TEI for DXU - Transmission interface type - Spare bits - CRC-4 - Available synchronization source - Network topology - LBO - FDL use - PCM receiver sensitivity ! TNOM parameters To enable DXX support in an RBS, the TNOM information in the IDB must be updated. The RBS node identity in the DXX network and the timeslot that shall be used for DXX communication with the RBS is specified. ! External alarms interface parameters Equipment that is connected to the external alarms interface for supervision is described by these parameters. It is possible to connect equipment for external alarms and antenna related faults. ! Hardware information for passive RUs Product number, hardware revision, serial number and a free text for passive RUs can be updated with this function. The hardware information is displayed in the inventory list in OMT. ! Hardware information for RBS 2106, RBS 2106i, RBS 2107, RBS 2112, RBS 2206 and RBS 2207 Product number, hardware revision, serial number and a free text for the cabinets above is updated when a faulty backplane is replaced. The hardware information is displayed at the Operation and Maintenance Center and in the inventory list in OMT. ! RBS identity Name and description for an RBS can be defined. If RBS identity has been defined for the RBSs in the network it can be used to verify that Remote OMT or Remote OMT over IP is connected to correct RBS. ! VSWR limits for antennas VSWR class 1 and VSWR Class 2 limits can be defined with these parameters. VSWR limits that are accurately defined and adjusted to the specific RBS will enable earlier detection of antenna system related problems. ! Loss for cables and feeders Loss values for cabinet external cables and feeders can be defined. The RX path loss is needed to calibrate the TRX and thereby optimize the RF performance of the RBS. The total RX path loss is also needed to calculate RXLEV at the antenna. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 15 (29) OMT Product Description ! ALNA/TMA parameters An ALNA/TMA is described by entering values for following parameters: - TMA type (GSM TMA, GSM By-pass TMA, TDMA TMA, TDMA By-pass TMA or externally powered TMA) - TX group delay - RX group delay - Loss - RX frequency range - Current supervision limits ! TF compensation value This parameter is used to specify the TF compensation value of a slave RBS in a TG cluster. ! Delay for ESB The ESB Delay parameter defines the delay of the synchronization signal in the ESB cable from master RBS to a slave RBS in the same TG Cluster. If this parameter is defined it overrides the automatically measured value. ! Delay for feeders The delay parameter specifies the RF signal delay in the feeder. The feeder delay is part of the total TX path delay and the total RX path delay in the RBS. The total TX path delay is needed to synchronize the TX burst transmission of all TRXs. The total RX path delay is needed to calibrate the timing in the receiver in the TRX. ! GPS parameters These parameters must be defined when a GPS receiver is used for GPS frame synchronization. The parameters are: - GPS RX delay - GPS RX DXU delay ! TF holdover mode This parameter makes it possible to specify if an RBS, configured to slave, should be in Intra-cell or Inter-cell hold over mode. ! Presence of RUs This parameter specifies if RUs, that can vary in number, are present or not present. ! System voltage This parameter is used to obtain optimal charging voltage for used batteries. System voltage that are accurately defined and adjusted to the used batteries will increase the battery lifetime. ! Battery parameters These parameters are used for optimal usage of used batteries. Battery parameters that are accurately defined and adjusted to the used batteries will increase the battery lifetime. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 16 (29) OMT Product Description ! 3.4.4 Battery backup time test parameters With these parameters the battery test feature is configured. The test checks the status of connected batteries and sends a fault report to the BSC if batteries are bad. The battery test feature gives information that is useful when planning battery replacements. Sending the IDB to the RBS To perform the last step in OMT configuration of an RBS, i.e. to send an IDB to an RBS for storage and usage, the function “Install IDB” is used. When the Install IDB function is initiated the OMT first performs a consistency check before starting sending the IDB to the RBS. The IDB is compared with the RBS HW information that can be retrieved from the RBS. The IDB and RBS consistency check reduces the risk that an IDB that doesn’t suit the RBS is installed. After execution of the Install IDB function the OMT and the RBS have the same IDB, i.e. the same description of the RBS. This enables maintenance functionality in the OMT. 3.4.5 Miscellaneous Some miscellaneous RBS configuration related functions are listed below. • Reading the IDB from the RBS The IDB stored and used by an RBS can be read by the OMT with the function “Read IDB”. After execution of the Read IDB function the OMT and the RBS have the same IDB, i.e. the same description of the RBS. This enables maintenance functionality in the OMT. • IDB file handling functions The function Save IDB makes it possible to save the IDB in OMT to a disk. The function Open IDB makes it possible to open an IDB stored on a disk. • Field configurations functions The thought with the field configuration functionality is that the personnel at the office create IDBs, which technicians shall use in the field, and save them as field configurations. Information can be attached to field configuration. To configure an RBS the field technician opens the correct field configuration, perhaps changes some parameter using define functions and then installs the field configuration. The functions are: - Field configuration – Attach information - Field configuration – Display information - Field configuration – Open - Field configuration – Save 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 17 (29) OMT Product Description • Site specific data functions Site specific data is the data that is entered in define functions.

For good performance it's recommended to use a Pentium 4-compatible processor, at least 1 GHz or more powerful. • At least 128 Megabytes of RAM • At least 50 Megabytes free hard disk space • 1 serial port (To be able to connect an OMT PC with only USB ports and no serial port, an USB-serial port adapter is needed) • Mouse (optional) • A VGA graphic card • A Thor-2-ISA card with a free ISA-bus slot or a Thor-2-PCI card with a free PCI bus slot (Remote OMT) • Printer (optional) • CD-ROM 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 25 (29) OMT Product Description 5 New functionality in the latest releases 5.1 BSS 06A Improved description of parameters: To minimize the risk to enter wrong values on IDB parameters in the OMT the following are described in the OMT help for each parameter that is handled: • What the parameter is used for • When the parameter must be defined • How to find out which parameter value to set • What happens if wrong parameter value is used? Improved usage of OMT-RBS transmission bandwidth: The bandwidth needed for OMT to RBS communication is reduced and optimized by compressing the information for functions that send a lot of data between OMT and RBS. Check IDB: This new function checks the IDB in the RBS and gives the user information about the IDB. The information that is given to the user is IDB type and IDB fault status. Check IDB is useful when performing RBS trouble shooting or when planning IDB replacement. More RBS information for support cases: To be able to support an operator efficiently Ericsson support (PLMBTS) sometimes need more information about the RBS than is possible to retrieve with the OMT today. This new functionality makes it possible to get the needed RBS information. Support for all new RBS 2000 Configurations in BSS 06A: See GSM/EDGE RBS product program for more information. 5.2 BSS R12 Increased transmission speed: The transmission speed between a local OMT and an RBS containing DXU-21 is dynamically increased from 19.2 kB/s up to 115 kB/s. Improved usage of OMT-RBS transmission bandwidth: The bandwidth needed for OMT to RBS communication is reduced and optimized by compressing the information for OMT functions that send a lot of data between OMT and RBS. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 26 (29) OMT Product Description Support for all new RBS 2000 Configurations in BSS R12: See GSM/EDGE RBS product program for more information. 5.3 BSS R11 Install IDB (Internal Data Base) without change of local/remote state: Local/remote state for DXU and TRU is stored in the IDB to survive a cold restart of an RBS 2000. In an IDB created with the OMT, local/remote state is always set to local. With the earlier implementations of the "install IDB" function, the local/remote state for TRUs is changed according to the IDB. This means that local/remote state for TRUs might be changed during "install IDB". In these cases the local/remote state might have to be changed back by the service technician by pressing the local button on TRUs. Usage of this new version of the "Install IDB" function will not cause a change in TRU local/remote state. This will reduce the risk for leaving the site with TRUs in the wrong state. RBS SW load indicator in OMT: An RBS SW load takes 20-30 minutes. During this time LEDs on the RBS 2000 are the only things that indicate that SW is being loaded. In earlier implementations of the OMT no progress has been indicated. With this new function it will be possible to see the RBS SW load progress in the OMT. Support for externally powered TMAs: (Tower Mounted Amplifiers) - Support for externally powered TMAs makes it possible to create an IDB describing an RBS 2000 HW configuration with externally powered TMAs (i.e. TMAs not powered from the RBS 2000). When configuring an RBS 2000 the OMT user specifies which type of TMAs that are used; internally powered GSM TMA, internally powered TDMA TMA or externally powered TMA. RBS Battery Log: Gives information about the battery condition. See FAJ 121 619 Battery Log. RBS Name in OMT: An operator defined RBS name is possible to store in the IDB using the OMT or Remote OMT. The name is used to identify the RBS or site according to a naming convention selected by the operator. The name is stored in the IDB and survives restart and power failure. The RBS name is visible in the display window for the RBS object in OMT and as site specific data. Support for all new RBS 2000 Configurations in BSS R11: See GSM/EDGE RBS product program for more information. 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 27 (29) OMT Product Description 6 Abbreviations IDB OMT RBS RU 22101-FGC101669 Uen Rev B 2006-06-19 Installation Data Base Operation and Maintenance Terminal Radio Base Station Replaceable Unit © Ericsson AB 2006 Commercial in confidence 28 (29) OMT Product Description 7 References Operational Instruction Remote Operation and Maintenance Terminal, Connect 3/154 31-APT 210 09 Uen User Description, Remote OMT over IP 240/1553-HSC 103 12 Uen GSM/EDGE RBS Product Program 1/159 42-FGB 101 097 Uen 22101-FGC101669 Uen Rev B 2006-06-19 © Ericsson AB 2006 Commercial in confidence 29 (29)
