This could even cause other cross-connections to be re-alloca-ted (removed-created) in order to provide for enough bearer capacity in consecutive time slots ata certain GXDI E1 link.Note: A 7390 platform identifies n*64 Kbits/s transport services, not presenting any link with ISDN rela-ted resources (i.e. OWSA-channels, B channels).•One free time slot of the selected TNT port in ISDN configuration can be cross-connected to the signalling time-slot on the NT side.•It is not possible to create a B-channel ISDN cross-connection if there is not created first a signalling cross-connection.•It is possible to cross-connect up to 8 free time-slots of the selected port and up to 8 B-channels of the 4 ISDN-BA user port, but just 1 cross-connection by NT port. Then, it is pos-sible to have 4 B-channel cross-connections by port.•2 cross-connections cannot coexist over the same NT port. So, if there is a B1 cross-con-nection and the user wants to do a B1+B2 cross-connection, he has to remove the B1 cross-connection before creating the B1+B2 cross-connection.

216/302 Issue 01 - April 2001 - Draft 04 3CC12424AAAA TQ BJA 012286.3 Preventive maintenancePreventive maintenance is carried out by:–permanent monitoring of the system provided by the supervision function,–periodic inspection of the equipment to ensure that:•the link cables between the NE elements are not damaged,•the external equipment is properly assembled,•the internal equipment is correctly in place.6.4 Corrective maintenance6.4.1 Alarms processingKnowledge of the implicitly induced alarms may be necessary for the operator to be able to carry outmaintenance and estimate the quality of the services offered by the 7390NE. This is why the presentdocument offers, in this chapter, a basic knowledge to the operator of the alarm correlation.6.4.1.1 Checking alarms for each equipment management functionThe "alarms control" functions of each board's equipment management for a given type of element areresponsible for supervision, clearing and masking of alarms for this element. Each of its functions isresponsible for notification to the SNMP agent of the starts and ends of alarms that it controls.The ANT board is in addition responsible for the processing of alarm indicators ("Critical", "Major" and"Minor" indicators).The AMD board implements an equipment management function for each of the following types ofelement:–the AMD itself–the IBS–the RBS–the NT–the static cross-connects on the radio link.The TNT board implements an equipment management function for each of the following types ofelement:–the TNT itself–the E1-G703 port of the TNTThe NT implements an equipment management function for each of the following types of element:–the E1-G703 port of the NT–the E1-G704 port of the NT–the Ethernet port of the NTAfter stopping the BS or resetting an ANT board (deliberately or not), DO NOT forget todownload again the same software on the available package (1 or 2) without activating norreferencing it, to re-create the NFS assembly point so as the new NTs that come in thenetwork can perform automatic download.
3CC12424AAAA TQ BJA 01 Issue 01 - April 2001 - Draft 04 217/3022286.4.1.2 Terminology relating to the alarmsActive alarm: an alarm is active as soon as the start of this alarm is notified to the ANT board, andremains so as long as its end is not notifiedAnomaly: discrepancy between the intended and real characteristics of an item. An anomaly may ormay not affect the capacity of this item to carry out a required function. Several successive anomalies ofthe same type are generally considered a fault.Defect: limited interruption of the capacity of an item to carry out the required function. A defect may ormay not necessitate maintenance action.Alarm clearance: clearing an alarm initiation by notifying its end.Board alarm function: for AMD, TNT, IBS, RBS or NT boards, the alarm function is the totality of the"Alarms control" functions of the elements that they manage.Alarm masking: Storage of an alarm without immediate notification of alarm initiation. Masking allowsthe seriousness of the alarms for a given element to be hierarchically ordered: masking is carried outwhen a higher order alarm appears. If on unmasking (carried out at the end of the higher order alarm)the alarm which was masked is still present, an alarm initiation must be notified.6.4.2 Definition of 7390NE alarms6.4.2.1 Alarms relating to boardsThe actions described are not necessarily controlled by the management software (they can becontrolled by the equipment itself).In the tables below, the term "board" may related to any part of the DBS (ANT, TNT, AMD, IBS, CPL,RBS, PSU, Fans), or to an NT.List of the alarms relating to the boards of 7390NE:Probable cause Alarm name Definition ActionsBoard mis-sing Board_missing 1. One of the boards (AMD, ANT, TNT, IBS, CPL), already known to the agent, is physically absent from the 7390NE.2. When the alarm object is the BS, it means that a load module (i.e.: a bus adaptative board, connected at the bottom of the rack) is physically absent.3.This alarm also occurs for NT creation, when the radio link is not established with the BS.Internal NE actions: depends on the functionalities and use of this board in the 7390NE.Operator actions:1. Install the missing board (see § 6.5). If the board is inten-tionally withdrawn, its suppression will make the alarm disappear (see 4.5.3)2. Contact the TAC(see page 3)3. No action

This procedure of (re)confguration is automatic and internal to the BS (as long as all the element configu-ration parameters are valid).Operator action: no action.Type mis-match Board_type_error 1.

Change the board (see § 6.5).2. Change the board or suppress the NT and recreate it.3. Check type of the ANT and CPL boards.Change the ANT or CPL board (see § 6.5).4.
