SIP Production Test
This section describes the production test supported by the D-Link SIP 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 SIP 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 SIP 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.
