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).

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 DT, dials the 
station number of Station “B.”

INSTALLATION TEST PROCEDURE
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
