The system shall have the possibility, upon receipt of relevant backward signals, tosuppress charging on calling subscriber.10.2.5 Reverse Chargeable NumberThe system shall provide possibility to assign parameters to any or many subscribers sothat, for any incoming call to that number(s), the system will send relevant backwardsignals to the originating exchange for non-charging the originating number and shallgenerate charge meter pulses on the terminating number. The generation of chargemeter pulses shall depend upon analysis of the A-number received.10.2.6 Shared Traffic LoadingThe system shall have the possibility to provide sharing of traffic load to a particulardestination. The sharing shall be activated in any or both of the following modes anddeviation shall be treated as “Minor Deviation”.a) Load Sharing Routing b) Call Sharing Routing10.2.7 Switching System SupervisionThe system shall be provided with the following (but not limited to) supervisionservices. Absence of any such facility shall be treated as “Critical Deviation”.10.2.7.1 Fault Detection and RecognitionThe system shall have the provision of automatic detection of abnormal operation andshall be able to recognize the causes to divide into definite “error” (for degradation ofsoftware performance) and “fault” (for degradation of hardware). Deviation shall betreated as “Major Deviation”.10.2.7.2 System ReconfigurationThe system, upon detection and recognition of error and/ or fault, shall be able toautomatically reconfigure itself in order to:a) switch the faulty equipment out of serviceb) generate a fault message with detailed physical location of the faulty equipmentc) start the automatic diagnosis protocold) record and print the results of the diagnosis teste) switch the stand-by equipment into servicef) generate relevant alarm messageDeviation shall be treated as “Major Deviation”.10.2.7.3 Fault/ Error ReportingThe system, upon detection and recognition of error and/ or fault, shall generaterelevant alarm message giving the exact date & time, reason and probable location ofthe fault.

10.2.10 Trunk SupervisionThe system shall be equipped with appropriate software to continually superviseoperational condition of trunks. On detection of failures and faults, relevant trunks willbe automatically blocked.

These thresholds shallbe pre-set, for individual trunk circuit groups, by commands. Deviation shall be treatedas “Major Deviation”.10.2.11 Traffic Supervision and ControlThe system shall be equipped with appropriate software to continually supervise at leastthe following aspects of traffic conditions:a) Abnormal increase in originating and incoming callsb) Heavy traffic congestion on any trunk circuit groupc) Overload in call processing equipmentOverload control procedures shall be automatically activated and relevant alarmmessages shall be generated. Deviation shall be treated as “Major Deviation”.10.3 Fault Diagnosis ProtocolThe system shall be equipped with necessary software programs to test all the softwareand hardware packages of the system. The testing can be initiated:a) Automatically, on periodic intervals to test all the packages, andb) Automatically, upon detection of any fault or trouble, orc) Manually, by commandsThe results of the test shall indicate, as exactly as possible, the physical location of thesuspected package/ card. Deviation shall be treated as “Major Deviation” but theabsence of such facility shall be treated as “Critical Deviation”.10.4 System RestartThe system shall be provided with the following restart facilities:a) Automatic restart in case of faults which relate to interruption of call processingfunctionsb) Manual restart, by command, in case recovery is not possible with automaticrestartc) Manual restart, by operation of some hardware switches, when manual restart bycommand is not possibled) Manual restart, when it is necessary to upgrade system softwaree) Cold restart, in case of complete power shutdownDeviation shall be treated as “Major Deviation”.10.5 Trunk Circuit Testing10.5.1 The system shall be equipped with automatic and manual test facilities for checkingproper functioning and localizing faults on trunk circuits. The facilities shall be accessedby commands.Book 2 :: Tender on Replacement of Old Telephones in Dhaka City Page: 51 of 153
