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.

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 031-1 through 031-3 in NAP-200-031, 
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 telephone 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.

tested.
Restore the temporary cross 
connections, temporary Office 
Data, etc. to the original.

Direct-In Termination Trunk (COT Card) 
Connection Test
START
On the MDF, make temporary 
cross connections between the 
Trunk for Direct-In Termination 
(DIT) and an LC.
C.O. Line Incoming Call Station “B” dials the telephone 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.
System Data SYS1, INDEX 72, SYS3, INDEX 0,

Stations “A” and “B” talk with each other.
Release Station “A” and “B” both go on-hook.

SND (RST Card) Connection Test
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 
telephone number of Station “B.”
Station “B” answers and talks
The call is released.
Restore the temporary cross 
connections, temporary Office 
Data etc. to the original.

Station “A” makes a Switch Hook Flash (SHF) and after hearing 
dial tone, dials the telephone number of Station “C.”
Station “C” answers the call.
Station “A,” after having talked with Station “C,” makes a SHF 
and confirms that a three-way connection has been set up.
The call is released.
