4. PORT CONNECTION TEST
4.1 Outline
Tests are to be performed on all the circuits of LC and Trunk circuit cards and PWR Supplies. LC and Trunk
circuit cards are tested with respect to their operations and speech path conditions. PWR Supplies are tested with
respect to howler tone and ringing signal.
While tests are in progress, the No. 0 CPU and TSW systems must be ACT (active).
4.2 Port Connection Test Procedure
The connection test procedure for each type of circuit card is described in the NAP indicated to the right of each
item in the following flowchart.

START
Make busy all ORTs On the front of the RST card, set all MBR switches (0-7) to 
the OFF position, making all ORTs busy.
From Station “A” (DP), test 
ORTs one circuit at a time.Un-busy (make idle) only the ORT to be tested.
Station “A” goes off-hook and after hearing dial tone, dials 
the station number of Station “B.”
Station “A” confirms ringing to Station “B” and Station “B” 
answers.
Stations “A” and “B” go on-hook.
From Station “B” (PB), test 
ORTs one circuit at a time.Un-busy only the ORT to be tested.

ATTCON (ATI Card) Connection Test
START
A station repeats an ATTCON 
call. Each ATTCON answers 
the call.Station “A” dials the operator access code (normally, “0”).
At each ATTCON, the operator confirms that the ATT lamp 
flashes and the ringer sounds.
At each ATTCON, the operator answers the call by pressing 
the ATND key.
Station “A” confirms speech with each ATTCON.
The operator at each ATTCON releases by pressing the 
CANCEL key.
Station “A” goes on-hook.
Each ATTCON calls a station 
by pressing LOOP keys one at a 
time.At each ATTCON, the operator dials the number of Station 
“A” by using LOOP keys (L1-L6) one at a time.
Ringing at Station “A” is confirmed.
Station “A” answers the call and confirms speech.
The operator at the ATTCON releases by pressing the 
CANCEL key.

Test Outline:
The purpose of this test is to confirm, by setting up an outgoing connection test for each outgoing trunk, that speech
can be made and that the call can be released.
Outgoing trunks must be tested one at a time using the sequence of Routes and Trunk Numbers assigned at each
office.
NAP-200-031
Sheet 1/3
Outgoing Trunk (COT, TLT, DTI Card) 
Connection Test
START
When a C. O. Line or Tie Line is 
not connected with a trunk circuit, 
temporary cross connections 
between the Outgoing trunk being 
tested and the terminating trunk 
should be set up on the MDF as a 
loop-back circuit.Referring to Figures 031-1 through 031-3, make temporary 
cross connections on the MDF for a loop-back circuit.
Temporarily assign Office Data from the MAT so that a loop-
back connection from the trunk can be established.
Make busy all Outgoing Trunks. On the front of the Trunk circuit card, set the MB switch to 
the OFF position, making the trunk busy.
Test the trunk circuits one at a 
time by establishing access from a 
station.Un-busy (make idle) only the trunk to be tested.
The station dials the Access Code of the trunk being tested 
and the number for the call destination.
The called side answers.
The station confirms speech.
The call is released.
Make temporary cross connections for the next trunk to be 
tested.
Restore the temporary 
connections, temporary Office 
Data, etc. to the original.
