Partially decodes SS7 messages, but does not support the decoding of MTP2 extended sequence numbers (used for high speed links).
monapp -b boardnum
A computer with a TX board installed
Windows or UNIX

Action |
1 |
From the command line prompt, navigate to the \Program Files\Dialogic\tx\bin directory under Windows or the /opt/dialogic/tx/bin directory under UNIX. |
2 |
Enter the following command: monapp -b boardnum where boardnum is the number of the TX board to open. At startup, the sample application attempts to bind to the monitor task and starts printing to the screen whenever a data indication is received. |

The monapp application partially decodes SS7 messages. monapp decodes the following information from the SS7 message header:
SS7 message length
Link number
Number of spares
Time stamp of each SS7 message.
For each SS7 message, a generic trace is displayed. For example:
=======================================================
Length: -- Link #:-- NumSpare: --
Number seconds: -- msecs: --
The following table describes the SS7 message data:
If the message length is... |
Then... |
Less than 3 bytes |
The trace, Bad message length --, displays. |
Equal to 3 bytes |
A FISU is decoded and the following trace displays: FISU: BSN BSN:BIB FSN FSN:FIB |
Equal to 4 or 5 bytes |
A LSSU is decoded. One of the following traces displays, depending on the LSSU type:
|
Greater than 5 bytes |
MSU and generic trace display. MSU: BSN BSN:BIB FSN FSN:FIB Additional traces display:
|
The following table describes the mnemonics that the SS7 message data displays:

FISU |
Fill in signal unit |
FSN |
Forward sequence number |
LSSU |
Link status signal unit |
MSU |

RLC |
Release complete |
SIE |
Status indicator emergency alignment |
SIN |
Status indicator normal alignment |
SIO |
Status indicator out of alignment |
SIOS |
Status indicator out of service |
SIPO |
