Risk of data loss
If you use the dbg128.exe utility without fully understanding its functions, you can
destabilize your system and cause a system crash or data corruption. Use this
tool only under the supervision of the Design team.

Select the board number; that is, the slot in which the board is
installed (for example, 4 for a 703t system connected to a Meridian 1
switch).
Select option 5 (500 ms polling time)
Result: The system launches the nbhaltswmon.exe utility and
displays a screen containing all the MPB96 registers. The status of
the registers indicates the status of the card. You can interpret the
card status by reading the bit significance in the MPB96 Unified
document.
The following examples illustrate the interpretation of register status:
Remarks
If all the parameters are set to 0, then no connection is made in
the time switch memory.
If the value displayed ends with 311 or 226, the board is configured
as slave; that is, it takes Voice bus clocking from a card configured
as master. If any other value is displayed, then the board is
configured incorrectly.
The typical value for a working system is 0x40077003. For example,
if the value starts with 0x402xxxxx, then a target abort operation
occurred on the PCI bus. The card does not work properly. If the
values of the last four digits change, check the green LEDs on
the back of the card. The changing values indicate that the DS30
connection is not stable or was lost
This register indicates the version of the board and the type of slot
in which the board is plugged (5V or 3.3V). For example, a typical
value is 0x80000a16, which indicates that the board is plugged into
a 3.3V slot (slot 8). For the 5V slot type, the value is 0; this indicates
that the card is plugged into the wrong slot. The firmware version
is a16, which indicates a release 1 board.
These registers have values when a target abort operation occurred
on a particular DSP. The DSP TA registers contain only zeroes
when the card operates normally.
