H.323 Production Test
This section describes the production test supported by the D-Link H.323
phone. The main hardware blocks to be tested are (i) LED, (ii) Key Scan, (iii)
Hook Switch, (iv) Codec & Handset, (v) Speaker, (vi) Memory and (vii) Ethernet
MAC and PHY. If a test is successful, the H.323 phone will play a Success tone
and turn on the Green LED. If a test fails, it will play an Error tone and turn on
the Red LEDs. After each test, press '1' to continue on to the next test and '0' to
repeat the test.
Note: In some tests the H.323 phone cannot determine the outcome of the test
and the user must verify it. In such test cases the phone will not play any tone.
