NDA-24238 CHAPTER 6 Page 451 Revision 3.0 SYSTEM OPERATIONS 10.3 Bad Call Notification (1) General When a station user has trouble because of hearing noise during a call, or has other difficulty having a normal call, the line involved is recorded as a bad call notification. The record displays on the MAT screen as system message [6-H], which indicates the recording source (Station Number), Called Station Number or Trunk Number, etc. (2) Operating Procedure SFC of the station user who can perform this operation must be allowed ASFC, SFI=46 SFC of the station user who can perform this operation must be allowed ASFC, SFI=46 Access code is assigned by ASPA command, CI=H, SRV=SSC, SID=46 System message [6-H] displays Switch hook flash (SST) Station user returns to talking state(SPDT) Dial access code for bad call notification Talking
CHAPTER 6 NDA-24238 Page 452 Revision 3.0 SYSTEM OPERATIONS 11. ROUTINE DIAGNOSIS For confirming its own servicing status, the system automatically executes self diagnosis every day, and dis- plays the result of the diagnosis on a system message. By this function, possible causes for trouble can be dis- covered in an early stage and possible trouble can be prevented from remaining undetected. 11.1 Related System Data ASYD, SYS1, INDEX86, b0 – When routine diagnosis starts, and the result of the routine diagnosis is normal, the result displays as system message [7-O]. 0/1: Not displayed/To display b1 – When the result of the routine diagnosis is abnormal, it displays as system message [7-P]. 0/1: Not displayed/To display b3, b2 – Processing at the time when Trunk Ineffective Hold is detected. Note Note:Trunk Ineffective Hold is a continuous state other than idle state within a predetermined duration while routine diagnosis is in progress. Whether it is to be detected/not detected is assigned by ASYD, SYS1, INDEX89. SYS1, INDEX87, 88 - Routine Diagnosis Start Time Start time should be such a time at which the traffic of the office is the lowest. To stop the routine diagnosis, set FF respectively to INDEX87, 88. BitExcept the trunks being held on two-way calls (station-to-station call, station-to-trunk, trunk- to-trunk call), the trunks being held at present are forcibly releasedAll trunks being held at present are forcibly releasedLENS of the trunk detected display as system message [7-P] b3 b2 0 0 10 1 0X — —— — XX X X INDEX 87 0 2 (Hour) 2:00 a.m. is the start time.
