NDA-24234 CHAPTER 5 Page 341 Revision 3.0 INSTALLATION TEST PROCEDURE NAP-200-040 Sheet 2/2 Connection Test-Paging Trunk for Paging Transfer Service Connection For Non-Delay-System Station “C” is connected to Station “A”. When Station “A” hangs up, Stations “B” and “C” are automatically connected with each other. For a Delay-System Station “A” rings and picks up handset Station “A” is connected to Stations “C”. When Station “A” hangs up, Stations “B” and “C” are automatically connected with each other. For Paging Transfer Supervision Station “C” is connected to Station “B”. Release END A
CHAPTER 5 NDA-24234 Pag e 34 2 Revision 3.0 INSTALLATION TEST PROCEDURE NAP-200-041 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 an- swer 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.

NDA-24234 CHAPTER 5 Page 343 Revision 3.0 INSTALLATION TEST PROCEDURE 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-200-042 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 DT. In about 12 seconds, the station hears ROT. 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 IM inm which the PWR Supply is to be tested. (analog port only) Confirm that ringing signal is sent out.

NDA-24234 CHAPTER 5 Page 345 Revision 3.0 INSTALLATION TEST PROCEDURE 5. OVERALL TEST 5.1 Outline Tests are to be performed to check C.O. Lines and/or Tie Lines by connecting them to a trunk on an individual basis. 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. START Overall Test of C.O. Line Outgoing Call:NAP-200-043 Overall Test of C.O.

CHAPTER 5 NDA-24234 Pag e 34 6 Revision 3.0 INSTALLATION TEST PROCEDURE NAP-200-043 Sheet 1/1 Overall Test for C.O. Line Outgoing Call START Seizure of trunk to be tested When seizing from a stationPlace 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 AT T C O N AT T C O N LC PBX A AT I AT I COT COT COT Central Office Exchange
NDA-24234 CHAPTER 5 Page 347 Revision 3.0 INSTALLATION TEST PROCEDURE 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-200-044 Sheet 1/1 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. Release When all COT trunks have been checked and a fault is detected.Perform a trunk loop-back test at the C.O. and identify whether the trunk side or the C.O. Line side is faulty. If the C.O. Line side is faulty, make a request to the C.O. for repair. END AT T C O N AT T C O NLC PBX AT I COT COT COT Central Office Exchange
