This is a new version of the AirLink CDPD Protocol Analyzer.
To update your analyzer with this version:

1. In the \analyzer directory,
   rename analyzer.exe to anaXXXX.exe
   rename analyzer.ini to anaXXXX.ini
   where XXXX is the date the file was created.

2. Copy analyzer.exe and analyzer.ini into \analyzer.

3. Check the .ini file to see if you need to customize any parameters
   for your site.


CHANGE_HISTORY

[October 20, 1995]

1.  Removed "DECODE FAIL" messages from the analysis window.  They
    are still available in the MAC statistics and in stat.log.

2.  Removed default display of 
	   "----Switching to channel NNN at ....."
	   "Forward Sync Found at ...."
	   "Forward Sync Lost at ....."   
    messages.  To see these messages, set PrintChanMsgs=1 in the
    initialization file (the default = 0).

3.  Fixed successful utilization statistic in playback mode.


[August 22, 1995]

1.  A screen pause/resume feature has been added.  F5 suspends the 
	screen display, allowing the Analyzer to continue decoding
	the protocols and writing to analysis.log and stat.log. 
	To stop the Analyzer, press F7.  To cancel the pause or to 
	re-start the Analyzer, use F4. 

2.      The analysis scrollback window has been significantly increased 
	in size. 
	The combination of this feature and the pause/resume feature greatly 
	improves the ability to review the contents of the analysis screen 
	while remaining on-line.

3.      The statistics displays have been upgraded and improved as follows:

	a)  All statistics screens are now updated in real time. 

	b)  An elapsed time display shows the time over which the statistics 
	    have been collected.
 
	c)  Statistics screens now include additional displays that show 
		what has happened over the most recent window of time. 
		The default window is 5 seconds, but it can be configured in 
		the initialization file.

	d)  MAC statistics now include information (BLER, etc.) based on what 
		the base station reports that it saw on the reverse channel. 
		This includes the measurement of successful utilization of 
		the reverse channel.

	e)      Changing channels no longer clears MAC statistics.

	f)      A new window reports throughput statistics.

	g)      A new file called stat.log has been added. This file contains 
			(1) event lines that index into analysis.log,  and
			(2) complete copies of the statistics. 

	h)  The statistics written to stat.log and analysis.log include
	    histograms that characterize reverse channel utilization.
		The statistics are alwaays written automatically on
		exit from the Analyzer.

	i)  The burst size monitor now runs continuously.
		
4.      The relative timestamp in the analysis window has been replaced 
	with a time-of-day stamp based on the systems internal clock, 
	using the form:
			 hh:mm:ss.ss
			    where: 
					hh = hours
					mm = minutes
					ss.ss = seconds and 100ths of seconds


[July 6, 1995]

1.  "Last Reverse RSSI" now displays a single sample taken during
    the first block of each burst received.

2.  Fixed bitstream printing of data captured when not synced
    to a forward channel.

3.  Display forward RSSI on all RRM frame decodes.

4.  Monitor first 1000 reverse bursts by default.

5.  Improved channel acquisition.

[June 12, 1995]

1.  Changed the format of some of the 1.1 RRM packet decodes.

2.  Allow the RF to be manually switched to the AMPS control
    channels and channel 991.
	  

[June 7, 1995]

1.  Compatible with CDPD 1.1.  Decodes, filters, and keeps statistics 
    on CDPD Versions 1.0 and 1.1.
    Still uses Version 1.0 Radio Resource Management for channel
    acquisition and hopping.
     

[June 1, 1995]

1.  Channel list in the INI file (if not empty) is now the only 
    list ever searched.  Broadcast lists are ignored.  Other channels
	can only be accessed via manual switches or directed hops.
    
2.  Improved channel acquisition in hopping environment.



[May 6, 1995]

1.  Improved initial acquisition to quickly lock on the
    strongest CDPD channel.

2.  Fixed intermittent loss of display in capture file analysis.


[April 26, 1995]

1.  Separated filtering of forward control flags and reverse 
	continuity bits.

2.  Fixed channel switching problem in 03/23/95 intermediate 
	release.
 
[March 23. 1995]

1.  Added burst size and idle time measurement capabilities. 

2.  Added real-time stamp to captured raw data files (like CAPTURE.DAT)
     that is displayed during file analysis.

3.  Tightened-up bitstream printing.


[February 28, 1995]

1.   When no signal is present, RSSI values are displayed as -113.
     (previously, were displayed as -114).

[February 22, 1995]

1.   Fixed problem with SREJ frame filter.

2.   Added algorithm to ignore non-initial SME and MNRP
     packet segments transmitted by half-duplex M-ESs.

[February 9, 1995]

1.  Added audible notification on channel changes.
    (See BeepTone in analyzer.ini)

2.  Added direct control of search mode to Radio menu.
    Switch Channel does not turn search mode off.
    Search Next does not turn search mode off.

3.  Added warning message if RF module is not communicating.

4.  Added ability to capture and playback channel change events.

[January 27, 1995]

1.  Radio Resource Management now acts like an M-ES.

2.  Modified TEI decode format to be displayed as follows:
      TEI[n]: x xx xx xx  
    where n = number of TEI bytes used in the MDLP header (1-4)
	  xx = 8-bit hex values of 27-bit binary TEI value with 
	  leading zeroes deleted.

      Example:TEI[3]= 11 
	  is displayed when the TEI value received in an MDLP
	  frame is as follows:  
	  02 00 23 ...

3.  Print Equipment ID in HEX (and ASCII, if printable).

4.  Added reverse color code display.

5.  Fixed problem in MAC control flag decoding.  If ever lost sync on
    forward channel, the control flag display was wrong for several 
    blocks after sync was re-acquired.

[January 13, 1995]

1.  Print Service Provider and Local Service Area Identifiers in hex
    (instead of ASCII and decimal respectively).

2.  When analyzing the MAC layer, the control flags for both directions
    are printed together if either direction is enabled.

3.  Fixed source and destination address display in best attempt TCP/IP
    analysis.

4.  Made XID decode accept any parameter lengths.



[December 23, 1994]

1.  When analyzer receives SWITCH_CHANNEL message, it will now
    do the directed hop even if not in search mode.


[December 6, 1994]

1.  Added best attempt TCP/IP analysis.
    Added size fields to IFRAME and IP analysis.
    Removed extra blank line on XID frame analysis.
    Split "Id Assign" analysis into 2 lines.
 
2.  Fixed filtering on TEIs. TEIs must be entered as display in MDLP
    analysis.
      
3.  No longer increment ulStatFwdAbortFrames counter for fill bits only.

4.  If locked on a channel when receive a Switch Channel packet, do not
    display the "switch to" channel number because analyzer does not
    switch.


[September 26, 1994]

1. Must exceed sync loss threshold within a specified time period
   before advancing to next RF channel.

2. Display the Service Provider ID in the Channel ID packets in ASCII.

3. Aligned the "ABORT FRAMES" statistic column in Log to Display window.


[September 16, 1994]

1. Filter settings are now saved on exit in file CONFIG.INI and are 
   restored on next execution.


[September 13, 1994]

1. Adjusted exec priorities so the keyboard could get some attention.

2. Moved the clearing of the slot counter from clearing of MAC stats.

3. Fixed SNDCP stats so they can be cleared.

4. Fixed the flaky behavior of file analysis when going on and offline.


[September 9, 1994]

1. Fixed the C/R bit on ID Assign, ID Check Request, and ID Remove
   packets.

[September 7, 1994]

1. Fixed SwitchChannel message TEI number problem.

2. Changed microslot counter to seconds, but still based on microslot count.

3. Miscellaneous internal restructuring.


[August 14, 1994]

Fixed Capture file crashes.

Added Maximum Capture file size parameter in .ini

August 5, 1994

1. Quick fix to partially eliminate hangs and resets when
   capturing. Complete fix coming.

2. For this rev, the capture file is limited to 1 mb. It
   will wrap around and keep capturing forever.
