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.
