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 ATTCON when a Ringdown Signal Interface is used, or with a station when a Dial-In Sig-
nal 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 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.
