MediaPack Series
7.4 Self-Test
The device features the following self-testing modes used to identify faulty hardware
components:

Startup Tests: These tests have minor impact in real-time. While the Startup tests are
executed, the regular operation of the device is disabled. When the test terminates,
the test results are reported via the EV_ENHANCED_BIT_STATUS event.
Additionally, if an error is detected, an error message is sent to the Syslog, TPNCP Lib
and SNMP trap. This phase consists of the following tests:
• BIT_ELEMENT_ID_TSA_PCM
• BIT_ELEMENT_ID_PSTN_FRAMERS
• BIT_ELEMENT_ID_DSP_CHANNEL
• BIT_ELEMENT_ID_VOICE_PATH_CONFIRM

Periodic Tests: These tests are started after the device starts up. This is a short test
phase in which the only error detected and reported is a failure in initializing hardware
components or a malfunction on the running hardware components. If an error is
detected, an error message is sent to the Syslog , TPNC event and SNMP trap. This
phase consists of the following tests:
• BIT_ELEMENT_ID_TSA_PCM
• BIT_ELEMENT_ID_PSTN_FRAMERS
• BIT_ELEMENT_ID_DSP_CHANNEL

User-initiated tests (Detailed): - The Detailed test is initiated by the user when the
platform is offline (i.e. not used for regular service). When the test terminates, the test
results are reported via the EV_ENHANCED_BIT_STATUS event. (Some of the tests
are reported via the old END_BIT EV.) Additionally, if an error is detected, an error
message is sent to the Syslog, TPNCP Lib and SNMP trap. This phase consist of the
following tests:
• BIT_ELEMENT_ID_SDRAM (enable diagnostics 1 ,2)
• BIT_ELEMENT_ID_FLASH (enable diagnostics 1(short test) , 2(long test))
• BIT_ELEMENT_ID_DSP_HPI (enable diagnostics 1 ,2)
• BIT_ELEMENT_ID_HOST_MII_PHY(enable diagnostics 1 ,2)
• BIT_ELEMENT_ID_ANALOG (enable diagnostics 1 ,2)
