Debugging and Diagnostics Parameters

This subsection describes the device's debugging and diagnostic parameters.

65.3.1 General Parameters

The general debugging and diagnostic parameters are described in the table below.
Table 65-18: General Debugging and Diagnostic Parameters
Parameter
[EnableDiagnostics]
LAN Watchdog
[EnableLanWatchDog]
[LifeLineType]
Version 7.2
Determines the method for verifying correct functioning of the different
hardware components on the device. On completion of the check and if
the test fails, the device sends information on the test results of each
hardware component to the Syslog server.

[0] = (Default) Rapid and Enhanced self-test mode.

[1] = Detailed self-test mode (full test of DSPs, PCM, Switch, LAN,
PHY and Flash).

[2] = A quicker version of the Detailed self-test mode (full test of
DSPs, PCM, Switch, LAN, PHY, but partial test of Flash).
Note: For the parameter to take effect, a device reset is required.
Enables the LAN watchdog feature. The LAN watchdog detects any
logical network failure.

[0] Disable (default)

[1] Enable & Reset = Enables LAN watchdog. If the device detects a
network failure, the device resets.

[2] Enable & No Reset = Enables LAN watchdog. If the device
detects a network failure, it does not undergo a reset.
The LAN watchdog periodically checks the device's overall
communication integrity by pinging the network. If the device detects a
communication failure lasting longer than three minutes, it performs a
self-test:

Test succeeds: The problem is due to a logical link failure (i.e., the
Ethernet cable has been disconnected on the remote switch) and the
following mechanisms are activated if enabled:

Busy Out (see the EnableBusyOut parameter)

Lifeline (see the LifeLineType parameter)

Test fails: The device resets (if the parameter is set to [2]) to
overcome the internal communication error.
Note:

For the parameter to take effect, a device reset is required.

LAN watchdog is applicable only if the Ethernet connection is full
duplex.
Defines the condition(s) upon which the Lifeline analog (FXS) feature is
activated. The Lifeline feature can be activated upon a power outage or
network failure (i.e., loss of IP connectivity). Upon any of these
conditions, the Lifeline feature provides PSTN connectivity and thus call
continuity for the FXS phone users.
If the device is in Lifeline mode and the scenario that caused it to enter
Lifeline (e.g., power outage) no longer exists (e.g., power returns), the
