introduction 1.4 maintenance process overview the purpose of this chapter is to provide an overview of the maintenance process and describe how to perform the correct maintenance procedures. 1.4.1 general rbs 2000 radio base stations are administered and controlled by the bsc. there is a master/slave relationship between the bsc and the rbs, and the bsc has an overview of the status of the radio network and its resources. the bsc manages the o&m of the rbs across the abis interface. the rbs equipment is seen as an mo by the bsc. this is a way of describing the rbs, in a functional way and as a logical model, in the bsc. all o&m actions are based on this logical model structure created in the bsc. an mo does not necessarily have a one-to-one relationship with a physical unit in the rbs. the mo, describing rbs 2000 (g12), is divided into two sub-classes: ao and so. the so is the abstract sub-class of the mo that owns the hardware. the ao only handles functions. the rbs can be set in local or remote mode. local mode means that the rbs has been disconnected and isolated from the bsc, while in remote mode the rbs is controlled by the bsc. when the rbs is in remote mode, the bsc acts as a master in the bsc- rbs relationship and all rbs maintenance actions are ordered by the bsc. faults in the rbs are reported to the bsc on an mo basis. all faults reported by the mos in the rbs are stored in the bsc error log. tests on mos with rbs hardware can be ordered by a bsc operator in order to check the status of the rbs. the operator can also test the connection between the bsc and a tru in the rbs by ordering a loop test. a test pattern is passed through the loop created between the bsc and one speci c time slot in a speci ed tru. the rbs contains test and supervision functions that detect malfunctions and report them to the bsc. tests and supervision are performed on an mo basis, which means that the different mos supervise their own equipment. statistics are collected on an mo basis in the bsc, for example, the number of call setup attempts, or the number of abnormally terminated calls. en/lzt 720 0011 r1a 2001-07-03 9 (201) ericsson radio systems ab ? all rights reserved ? free datasheet http://

  figure 5 the rbs maintenance process preparatory actions writing work order as a result of the fault analysis a work order is written. the work order includes information about site location, how to get to the site, cabinet identity, the suspected ru and site history. an error log is included if the fault is de ned as logical. note: the chapter safety instructions must be read through to ensure knowledge of potential risks prior to beginning work on the rbs equipment. the work order is analysed before personnel are sent to the site. the owchart(s) in the chapter fault localisation that concern the faulty unit(s) is read. this providesinformation on: ? selecting the spare parts and tools required at the rbs site. ? informing the omc operator if the site visit requires taking the rbs out of traf c or reduces rbs functions. to be done at the site fault tracing 12 (201) en/lzt 720 0011 r1a 2001-07-03 ericsson radio systems ab ? all rights reserved ? free datasheet http://
introduction the chapter fault localisation provides methods for nding the faulty unit in the rbs that causes the alarm reported to the bsc. for example, when the work order denotes that a tru is faulty, fault localisation will point out the position of the faulty tru. all alarms given in the ru maps correspond to a section in the chapter fault localisation . replacing faulty unit the chapter rbs field repair describes how to replace a faulty unit. testing the rbs is tested before the eld technician leaves the site. the chapter test after repair describes how to verify that the rbs is functioning properly. writing work report the chapter concluding routines provides information on the different administrative routines that must be performed before leaving the site. after maintenance handling of replaced units the chapter concluding routines describes which units are repairable and which are disposable and the different administrative routines connected to both. 1.4.5 fault cases the purpose of this section is to explain the different fault cases that can arise in the rbs 2000. this forms the basis for choosing between different methods when localising a detected fault. ? unambiguous indication with an indicator and an ru map. ? unambiguous indication with an ru map only. ? unit that is unambiguously indicated, but consists of several replaceable parts. ? logical ru indicated. note that the bss only pinpoints one ru in the ru map. indication with an indicator and an ru map examples of units dxu, dtru, cxu, psu and cdu method of localisation the work order states which unit is affected. when the cabinet is opened, a red fault indicator will be on in the faulty unit. if this indicator should be defective, only an rbs fault indicator will be on. in this case, the omt is used to localise the faulty unit. en/lzt 720 0011 r1a 2001-07-03 13 (201) ericsson radio systems ab ? all rights reserved ? free datasheet http://
introduction indication with an ru map examples of units rx cables method of localisation the work order states the unit concerned. the maintenance manual is used to nd out where the unit is located. indication of units that consist of several replaceable parts examples of units fan unit method of localisation the work order states which unit is affected. the omt is used to identify which parts are faulty, for example, which fan is faulty. logical ru indicated the logical ru is identi ed when it is not obvious which physical ru is faulty. for example, epc bus can be indicated, which means that anything connected to it can be faulty. examples of units cdu bus, eom bus, epc bus, y link and environment. method of localisation a systematic order of replacement is used to determine the unit that has generated the fault. the following applies to the logical ru environment this logical ru records conditions that cannot be affected from the rbs. the ru is divided into two parts: ? external power and climate (condensation, air humidity and temperature). when this ru is identi ed, the omc operator must analyse the fault to determine possible rbs repairs. the omc operator must be able to determine whether the reported fault requires maintenance personnel to respond or not. ? in the case of the fault message "indoor temperature out of safe range", the trouble may cease when local weather conditions change, that is, the sun sets or the temperature changes. alternatively, in the case of external power fault it is necessary to determine whether or not the cause of the fault is a commercial power failure, prior to dispatching maintenance. if a technician is sent, the work order must include the fault history for the rbs. 1.5 how to use this manual detailed information about the use of this manual and how to perform maintenance in the correct order, is found in the section maintenance process overview in this chapter. a brief description of the contents of each chapter of this manual is given below. 14 (201) en/lzt 720 0011 r1a 2001-07-03 ericsson radio systems ab ? all rights reserved ? free datasheet http://

rbs field repair 5 rbs field repair the instructions in this chapter describe the replacement of rus and how to put the rbs into operation after a fault has been localised in the rbs. 5.1 local/remote mode the local/remote button can change ru mode between local and remote control. a local/remote button is located on the dxu and the dtrus. rus in local mode do not have communication with the bsc via the abis interface and are therefore isolated from the bsc. the local/remote button is used to isolate the unit from the bsc, for example, when exchanging faulty units in the rbs. rus cannot be changed to remote mode until the data base has been downloaded to the dxu. below is a brief description of the two different changes of state and how to stop a change of mode to remote. , 
 

  

 figure 37 control panel on dtru 5.1.1 changing ru mode from remote to local ? the local/remote button is pressed. ? the system disables the local/remote button in order to prevent mistakes. ? the local mode indicator starts ashing to indicate that a change of ru mode to local is in progress. ? the operational indicator turns off in order to indicate that the ru has been taken out of operation. ? a fault report message is sent to the bsc via the abis interface. this means that an external condition class 1 alarm will arise in the bsc. ? the communication link on the abis interface is disconnected and the ru mode is changed to local. en/lzt 720 0011 r1a 2001-07-03 93 (201) ericsson radio systems ab ? all rights reserved ? free datasheet http://
rbs field repair ? the indicators rf off and local mode both turn on. the operational indicator is also turned on, if the ru is free from class 1 faults, in order to indicate that the ru is in local operation. ? the system enables the local/remote button again. 5.1.2 changing ru mode from local to remote ? the local/remote button is pressed. ? the local mode indicator starts ashing to indicate that a change of ru mode to remote is in progress. ? the operational indicator turns off in order to indicate that the ru has been taken out of operation. ? the communication link on the abis interface is established by order from the bsc. the ru is changed to remote mode immediately after the link towards the bsc has been established. ? the indicators rf off and local mode both turn off. ? in order to indicate that the ru is ready to carry traf c, the operational indicator turns on. note that this will only happen if the ru is considered as operational by the bsc. (for example, the unit may be blocked from the bsc.) 5.1.3 stopping a change of ru mode from local to remote if the local/remote button is pushed while the local mode indicator is ashing, the change of ru mode to remote is interrupted. note: this function is only valid during a change of ru mode from local to remote. ? the local/remote button is pressed. ? the attempt to enable a connection with the bsc will stop. ? the ru will then remain in local mode with the communication link disconnected and the indicators rf off and local mode both remain on. 94 (201) en/lzt 720 0011 r1a 2001-07-03 ericsson radio systems ab ? all rights reserved ? free datasheet http://

spare parts philosophy for rbs 2000        the specifying and classifying of spare parts is done during the service preparation process which is a part of the industrialization process. the result is a spare part list containing three classes of spare parts:  recommended for customer stock. intended to be replaced on site and intended to be repaired at ericsson repair center or by the local service organisation (code = u)  recommended for customer stock. intended to be replaced on site or at local shop and intended to be disposed after consumption (code = r).  not recommended for customer stock. the parts are available when needed (code = a). the spare parts catalogue is adapted to this structure. the dimensioning and recommendation of spare parts will not follow the principle one-of-each- board-in-use unless the customer expressly so insists. the dimensioning and recommendation of spare part stocks is and will be done with a computer-based calculation model for bts equipment. the tool is working with the parameters:  product reliability (mtbf)  spare part delivery lead time or repair turn around time.  chosen service level (spare part management).  the spare part structure.  quantity of each unit in operation to be supported by the specific stock.  the probability of shortage.    .  the catalogue is divided into separate chapters, depending on recommendations (classifications). position numbers put in brackets ( ) are associated parts, not necessary shown in illustrations. position numbers with letters, like 3a, 3b are alternative products. new products are indicated by a #-sign in front of the position number. parts without product number may be shown on illustrations, but are not recommended for customer stock, or may be included in a spare parts set (and not separate orderable). if a reference to another chapter is given, more information will be found there. en/lzt 720 0012 r1a ? ericsson radio systems ab 9 (59) 2001-06-06 - all rights reserved - free datasheet http://
