    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.

    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.

    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

    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.

    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.

    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.
