INSTALLATION TEST PROCEDURE
If the TLT is a 4W E&M System, connect the related leads as shown below.
Set up a loop-back connection between the DTI Trunk to be tested and another DTI Trunk as shown below:
Figure 032-3  DTI Test Configuration
If the office is the primary office (Clock-Source-Office), perform the tests by disconnecting the PLO and the
M-OSC.  (The mode of the PLO becomes “Self Operation Mode.”)

INSTALLATION TEST PROCEDURE
Test Outline:
The purpose of this test is to confirm, by setting up an incoming trunk connection test for each incoming trunk, that
speech can be made with the ATTCON when a Ringdown Signal Interface is used, or with a station when a Dial-In
Signal Interface is used. This test also confirms that the call can be released. Incoming trunks must be tested one at
a time using the sequence of Route and Trunk Numbers assigned at each office.

Sheet 1/2
Incoming Trunk (COT, TLT, DTI Card)
Connection Test
START
On the MDF, make temporary 
cross connections between the 
Incoming Trunk to be tested and an 
outgoing trunk as a loop-back 
circuit.Referring to Figures 032-1 through 032-3 in NAP-200-032, 
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 other than the cross-connected trunk.
Test Incoming trunk circuits one at a time.
For Ringdown Signal 
Interface.Station “A” dials the station number of Station “C”.
The call terminates to an Attendant Console.
The Attendant Console answers the call and confirms 
speech.
The call is released.
Make temporary connections for the next trunk to be tested.

an LC.
C.O.Line Incoming Call Station “B” dials the number of LC “C” (Station “C”).
Incoming Call to Station via 
DIT Trunk.The call terminates to Station “A”; Station “A” rings.
Confirm that the ringing is distinct from that of an intra-
office call or ordinary C.O. call.
The ringing signal for Direct-In Termination calls can be 
the same as that used for C.O. calls if the related Office 
Data is assigned.

START
When a C.O. Line or Tie Line is 
not connected with the trunk, 
make an arrangement for trunk 
loop-back as illustrated above.On the MDF, make temporary cross connections for a 
loop back circuit.
Temporarily assign Office Data from the MAT so that a 
connection can be set up with Station “B” via a SND.
Make  busy  all  SNDs On the front of the RST circuit card, set all MBS switches 
(0-7) to the OFF position, thereby making all SNDs busy.
Test SNDs one after another Un-busy (make idle) only the SND to be tested.
Station “A” dials the access code of the trunk and the 
station number of Station “B”.
Station “B” answers and talks
The call is released.
