BRI Tools
---------

The BRI Tools window contains icons for launching two diagnostic and support tools that can be used for checking, troubleshooting and monitoring your ISDN BRI line.  These tools are the "Line Monitor" and the "Protocol Monitor".

Line Monitor
------------

The Line Monitor tool allows you to check and monitor connectivity of the BRI line.  The Line Monitor provides a representation, in the form of virtual LEDs, of the the connectivity at the three protocol layers provided by the BRI ISDN Adapter (the layers are: physical (L1), link (L2) and network (L3)).

On-line, context-sensitive help is available for each LED (click on the LED you want information about).  Each LED can be in one of two states:

	GREEN:	the layer is up and operating properly.
	
	RED:	the layer is down or not operating properly.

When a layer is not up the on-line help will inform you of the nature of the problem and suggest possible remedies.

Using the Line Monitor with multiple 
------------------------------------

Each USR BRI Adapter is assigned a unique system adapter number when the adapter is installed using the Control Panel. Select Network from the Control Panel to see the adapter number(s) assigned to the installed BRI Adapter(s).
 
When the Line Monitor initializes it searches for all installed BRI Adapters and then automatically attaches to the adapter with the lowest system adapter number.  The adapter number of the currently connected adapter is displayed in the Line Monitor's Title Bar (e.g., BRI ISDN Adapter #30).  If the Line Monitor is not connected to an adapter the Title Bar will read "BRI ISDN Line Monitor".

To disconnect from an adapter select 'Disconnect' from the Settings drop-down menu.

To connect to an adapter, select 'Connect to...' from the Settings drop-down menu.  A dialog box listing all BRI Adapters in the system will be displayed.  Select which adapter to connect to.

Protocol Monitor
----------------

The Protocol Monitor tool is used to monitor protocol messages on the ISDN BRI D-channel.  These messages are used for call control and maintenance and can be helpful in assisting ISC and telephone company support personnel when diagnosing connection problems.  The Protocol Monitor can be launched in three ways: from the Protocol Monitor icon, from the Line Monitor tool, and from the MS-DOS prompt.

Launching the Protocol Monitor from the Protocol Monitor Icon
-------------------------------------------------------------

Select the Protocol Monitor Icon in the BRI Tools window.  The Protocol Monitor will attach to the BRI ISDN Adapter with the lowest system adapter number. 

Launching the Protocol Monitor from the Line Monitor
----------------------------------------------------

Select 'Launch' from the Line Monitor's Settings drop-down menu to launch the Protocol Monitor.  The Protocol Monitor will display D-channel messages for the currently selected adapter. 

Launching the Protocol Monitor from the MS-DOS prompt
-----------------------------------------------------

You can start the Protocol Monitor from the command line by typing:

	fxshow [adapter number]

where [adapter number] is the system adapter number assigned to the BRI ISDN Adapter in the Control Panel's Network settings.

If the adapter number parameter is omitted, fxshow will attach to the BRI ISDN Adapter which has the lowest system adapter number.

The Protocol Monitor is installed to the '%SystemRoot%\system32\usr\bri' directory, where %SystemRoot% is the base path of your Windows NT installation.  You must be in this directory or have the directory in your default path to launch the Protocol Monitor from the MS-DOS prompt.

Pausing Protocol Monitor output
-------------------------------

At any time you can pause Protocol Monitor output by selecting the <CTRL-S> key combination.  Once output is paused, you can use the scroll bar controls to examine the output data.

Resuming Protocol Monitor output
--------------------------------

You can resume output by typing <CTRL-Q>.

Saving Protocol Monitor output to a file
----------------------------------------

If you have paused the Protocol Monitor's output, you can save selected text to a file by using the Protocol Monitor's Edit controls to mark and copy the data which can then be pasted into a text file by a text editor (Notepad, etc).

Alternatively, the Protocol Monitor output can be redirected to a file by invoking the Protocol Monitor at the MS-DOS prompt using the following syntax:

	fxshow [adapter number] > filename 

where [adapter number] is the system adapter number assigned to the BRI ISDN Adapter in the Control Panel's Network settings.
