NDA-24306 CHAPTER 5 Page 343 Revision 1.0 NAP-200-040 Sheet 1/1 Radio Paging Trunk (COT Card) Connection Test START Call the Radio Paging Equipment Station “A” dials the radio paging access code and hears special dial tone from the Radio Paging Equipment, then dials the slave station number. The paging radio of the slave station starts ringing. By hearing CRBT (Continuous Ring Back Tone) from the Radio Paging Equipment, Station “A” confirms that the slave station is being paged, then goes on-hook. The paged party answers The slave station (the radio-pages party) dials the paging answer code at the nearby Station “B”, hears SPDT through the Radio Paging Equipment, then dials the paging answer code. Station “A” rings and picks up the handset. Confirm that Stations “A” and “B” can talk with each other. Release Stations “A” and “B” both go on-hook.

CHAPTER 5 NDA-24306 Page 344 Revision 1.0 Test Outline: The Howler Tone Generator and the Ringing Generator are equipped on the PWR Supply. The purpose of the test is to confirm ringing signal by setting up a station to station connection and a howler tone connection from a station accommodated in any PIM. NAP-200-041 Sheet 1/2 Howler & Ringing Signal Test START Check PWR0 in each PIM. While both PWR Supplies are OFF, turn power to PWR0 ON. Leave PWR1 OFF. Check howler tone. A station accommodated in the PIM for which the PWR Supply is to be tested goes off- hook. (analog port only) The station hears dial tone. In about 12 seconds, the station hears reorder tone. About 30 seconds later, the station should confirm hearing howler tone. Check ringing signal. Set up a station-to-station connection between two stations accommodated in the PIM in which the PWR Supply is to be tested. (analog port only) Confirm that ringing signal is sent out.

CHAPTER 5 NDA-24306 Page 346 Revision 1.0 5. OVERALL TEST 5.1 Outline Tests are to be performed to check the following lines by connecting them to a trunk on an individual basis: C.O. lines FCCS (Fusion Call Control Signal) - If the system has a connection with other IPX and/or IMX series via Fusion link Tie lines - If the system has a connection with tie lines including CCIS The speech path conditions (speech level, presence of noise, one-way speech, no speech, etc.) over the connec- tion to the distant office will be checked. Release of the trunk used will also be checked. 5.2 Overall Test Procedure The procedure for performing the Overall Test is described in the NAPs indicated to the right of each item in the following flowchart.

NDA-24306 CHAPTER 5 Page 347 Revision 1.0 NAP-200-042 Sheet 1/3 Overall Test for C.O. Line Outgoing Call START Seizure of trunk to be tested When seizing from a station Place the trunk to be tested into idle state, and make all other trunks busy. Station “A” dials the trunk access number. Station “A,” after hearing dial tone from the C.O., dials the pilot number for the local office and allows the call to be terminated to that office via loop-back at the C.O. When seizing from an ATTCONAn ATTCON sets up the connection with a specific trunk designated via Individual Trunk Access service. The ATTCON, after hearing dial tone from the C.O., dials the pilot number for the local office and allows the call to be terminated to that office via loop-back at the C.O. Call termination to ATTCON The call looped back at the C.O. terminates to the ATTCON. Check of speech conditions After the call has been answered at the ATTCON, check the speech conditions including speech level, presence of noise, and one-way speech state. Release When all COTs have been checked and a fault is detected.Perform a trunk loop-back test at the C.O., and determine whether the trunk side or the C.O. Line side is faulty. If the C.O. Line is faulty, make a request to the C.O. for repair. END

CHAPTER 5 NDA-24306 Page 350 Revision 1.0 Test Outline: The tests comprising this NAP are to be performed according to the C.O. Line Number Table provided by the C.O. If the C.O. Line Numbers are not known, tests cannot be performed because loop-back cannot be performed at the C.O. In addition, tests cannot be performed which involve Direct Inward Dialing. Under such circumstances, the C.O. must be asked to perform an incoming test. NAP-200-043 Sheet 1/3 Overall Test for C.O. Line Incoming Call START Seizure of trunk to be tested From the ATTCON, set up a connection with a specific trunk designated via Individual Trunk Access. After hearing dial tone from the C.O., dial the C.O. Line number of the trunk being tested from the ATTCON. Call termination to ATTCON The call looped back at the C.O. terminates to the ATTCON. Speech Condition Check After the call has been answered at the ATTCON, check the speech conditions including speech level, presence of noise, and one-way speech.
