Release notes for version 5.2.4 of LEDR Embedded Firmware
Release 5.2.4 contains the following versions of firmware:
#
#
Application:    5.2.4
DSP:            1.4.0
FPGA:           1.31
Modem Scripts:  2.10
Option FPGA:    1.68
Release Date:   07/23/2004

#	Please note that the upgrade instructions are contained at the end of 
# 	this document.


!!!!NOTE!!!!
Please note that in addition to following the instructions at the
end of this document there is also a procedure that needs to be
followed in order to allow for upgrading from an older version of
software.  Because of a mapping issue the event map of the radio becomes
corrupted on an upgrade.  In order to avoid this the following procedure
needs to be observed:

1. Before begining the reprogram, as described at the end of this
   document, save your event map using the "evmap send" command.

2. After reprogramming the radio and booting into the new code issue
   an even map clear by using the "events init" command. It is also
   recommended that the log file be cleared with a "log clear"
   command.

3. After clearing the event map, step 2 above, reload the desired map
   (saved in step 1) using the "evmap get" command



This software contains the following additions and modifications:

			NEW FEATURES:
		------------------------------

1) None


			DEFECT FIXES:
		------------------------------

1) TR2XXX: Network upgrade non-functional, with 5.2.3

			KNOWN ISSUES:
		------------------------------

1) Front panel may intermittently scroll menu when the network is
   heavily congested.  Work around by correcting network congestion
   issues.

2) "loopback outb" command does not work everytime due to intermittent
   3rd party vendor hardware limitation.  Re - issue command again.

3) "Reprogram Network" sometimes fail with protected system.  Work
   around by configuring radio to standalone and remove redundant
   cable.

4) !!! NOTE !!!
   An upgrade to this version of software from 4.4.6 and earlier
   software versions will cause the existing radio EVMAP settings to
   be reset to their default values.  If the settings have been
   modified from their defaults, the mapping can be stored and
   retrieved using the EVMAP command and a computer running the ledr
   tftp application.

5) When using 1+1 configuration, ensure that both radios are upgraded
   to 5.2.2 before using the protected mode test mode feature ("rdnt
   pmode")

6) Due to reliability issues, RAI generation (for the T1/E1 interface)
   has been disabled for quite some time.

7) The console baud rate is configurable ONLY for the radio applications.
   The LEDR bootstrap loader remains hard-coded at 9600 baud.

8) The UDP checksumming feature can only be enabled/disabled when the 
   ethernet interface is set to "ETH"

9) When in a hot-standby (1+1) configuration the serial service channel
   port issues duplicate characters on the port

#
Release notes for version 5.2.3 of LEDR Embedded Firmware
Release 5.2.3 contains the following versions of firmware:
#
#
Application:    5.2.3
DSP:            1.4.0
FPGA:           1.31
Modem Scripts:  2.10
Option FPGA:    1.68
Release Date:   06/23/2004
#	Please note that the upgrade instructions are contained at the end of 
# 	this document.
#
#
This software contains the following additions and modifications:

			NEW FEATURES:
		------------------------------

1) TR2741: UDP checksumming is now configurable via the web interface.

2) TR2808: The console baud rate is now preserved across system resets.

3) TR2803: G.821 statistics for the composite link are now available
   via the web interface.

4) Miscellaneous improvements to the RF modem.


			DEFECT FIXES:
		------------------------------

1) TR2693: rfocal now properly terminates the end of the RF output
   power calibration table.  Formerly, it would append a bogus entry
   to the end of the table.

2) TR2809: The rfout "offset" feature now works properly.  Formerly
   minimum and maximum RF output power values were reported WITHOUT
   accounting for the power offset and the power value at the low end
   of the calibration table was not settable.

3) TR2667: The "g821 clear all" command now logs a G821_COUNTERS_CLEARED
   event (146) instead of LINK_UNAVAILABLE.

4) TR2674: UDP checksumming may now be set if the "IP port" is set to
   AIR.  Formerly, it would always remain ON.

5) TR2722: The UDP checksumming menu item for the front panel display
   now displays "UDP CHECKSUM".  Formerly, it would display "UDP CHECKSUMMIN"

6) TR2701: Killing non-existant telnet sessions is now handled gracefully.
   Formerly the radio would stop responding and eventually reboot.


			KNOWN ISSUES:
		------------------------------

1) Front panel may intermittently scroll menu when the network is
   heavily congested.  Work around by correcting network congestion
   issues.

2) "loopback outb" command does not work everytime due to intermittent
   3rd party vendor hardware limitation.  Re - issue command again.

3) "Reprogram Network" sometimes fail with protected system.  Work
   around by configuring radio to standalone and remove redundant

###############################################################################
#
Release notes for version 5.2.2 of LEDR Embedded Firmware
Release 5.2.2 contains the following versions of firmware:
#
#
Application:    5.2.2
DSP:            1.4.0
FPGA:           1.31
Modem Scripts:  2.00
Option FPGA:    1.68
Release Date:   03/16/2004
#	Please note that the upgrade instructions are contained at the end of 
# 	this document.
#
#
This software contains the following additions and modifications:

			NEW FEATURES:
		------------------------------

1) Composite G.821 statistics are displayable for radios in a 1+1
   configuration via the "g821 comp" command.

2) Signal-to-noise ratio (SNR) is logged with events.  See the
   "log" command.

3) UDP packet checksumming is configurable (for TFTP and SNMP) via
   the "ip" command.

4) Redundant mode test mode configuration is persistent and its
   timeout is configurable.  See the "rdnt" command for usage.


			DEFECT FIXES:
		------------------------------

1) The switchover temperature threshold event (configured via "rdnt
   temp") logs a TEMPERATURE event in the event log.  Formerly no
   event was logged.

2) The "trend ifec" command displays instantaneous statistics.
   Formerly it displayed cumulative statistics.

3) The "fec" and "log" commands accept the abbreviated "clr"
   sub-command.  The "g821" command accepts the "clear" sub-command.

4) The demodulator self-test ("test demod") restores the demodulator
   to normal operating state upon completion.  Formerly it didn't,
   effectively bringing down the RF link.

5) The web interface allows configuration of system description and
   system time via the "general" configuration frame.

6) The web interface preserves the event log viewing filter selections
   across visits to the event log web page.

7) AIS (for the T1/E1 interface) is properly generated for hitless
   systems.  Formerly if either modem in a hitless system unlocked,
   LEDR would generate AIS.  Now both modems must fail for AIS to be
   generated.

8) AIS (for the T1/E1 interface) is properly generated for the dual
   upstream/downstream failure case.  Formerly LEDR would treat local
   RAI as higher priority than AIS from another system (and RAI is
   disabled--see below).

9) Transmitter output power is properly reported (via "rfout") when
   the output power is truly outside the calibration points, most
   saliently when the transmitter is powered off ("txkey off").

10) TFTP "config get" and "config getall" run to completion.  Formerly
    these commands locked up processing the transceiver settings.

11) The eia530 command is able to set DTR and RTS from telnet from an
    account with write permissions.  Formerly it would decline, citing
    "insufficient permissions".

12) Fixed a bug with the raw service channel.

13) Corrected inaccuracies in G.821 counters.


			KNOWN ISSUES:
		------------------------------

1) Front panel may intermittently scroll menu when the network is
   heavily congested.  Work around by correcting network congestion
   issues.

2) "loopback outb" command does not work everytime due to intermittent
   3rd party vendor hardware limitation.  Re - issue command again.

3) "Reprogram Network" sometimes fail with protected system.  Work
   around by configuring radio to standalone and remove redundant

   to 5.2.2 before using the protected mode test mode feature ("rdnt
   pmode")

6) Due to reliability issues, RAI generation (for the T1/E1 interface)
   has been disabled for quite some time.

Option FPGA:    1.68
Release Date:   12/9/2003
#	Please note that the upgrade instructions are contained at the end of 
# 	this document.
#
#
This software contains the following additions and modifications:

			NEW FEATURES:
		------------------------------
1) Protected Composite Changes - traffic quality
		This change gives a measure of the uncorrectable errors with hitless
		switching enabled in a protected system.  The concept of a
		"Composite Uncorrectable Block" has been added to both the trend
		and the fec commands.  The count value is a measure of the number
		of simultaneous uncorrectable blocks given the receive data from
		both receivers.

2) Calibration of the entire subband
		This change applies to 1400's only.  Customers want to be able to
		change frequencies of their radios, but currently they are
		calibrated only at the ordered frequency of the radio.  We will
		now calibrate the rssi and output power values at various frequencies
		throughout the band in order to support this.

3) G.821 reset all from SNMP
		The demod G.821 reset all SNMP object now clears all G.821 stats.

4) Log Unrecoverable FEC alarm
		Whenever uncorrectable blocks are encountered, this event is
		logged.  This event will be generated no more than once per minute
		so that a burst of errors will not saturate the event log.


			DEFECT FIXES:
		------------------------------
1)	Network node dropout problem
		Nodes in the network list have sometimes spontaneously dropped
		out for periods of time.  Although it has been a problem with
		previous versions of software, the problem had become more
		pronounced with version 5.0.

2)	Command inconsistencies (fec, trend commands)
		The fec and trend commands did not allow upper and lowercase letters
		as with all other commands.

3) Modify time via web server
		The web server previously would allow date changes, but not time.

4) Warm Standby
		Warm standby operation is now functional.

5) Transmitter lockup problem
		A transmitter lockup condition due to periods of faded signal
		strength has been identified and fixed.

6) Charge pump change - microphonics
		The charge pump currents for the 1400 series synthesizers have
		been changed to improve microphonic performance.


			KNOWN ISSUES:
		------------------------------
1) Front panel may intermittently scroll menu when the network is heavily congested.   Work around by correcting network congestion issues.

2) "loopback outb" command does not work everytime due to intermittent 3rd party vendor hardware limitation.  Re - issue command again.

3) "Reprogram Network" sometimes fail with protected system.   Work around by configuring radio to standalone and remove redundant cable.

4) !!! NOTE !!!
   An upgrade to this version of software from 4.4.6 and earlier software
	versions will cause the existing radio EVMAP settings to be reset to
	their default values.  If the settings have been modified from their
	defaults, the mapping can be stored and retrieved using the EVMAP
	command and a computer running the ledr tftp application.

#
Release notes for version 5.0.0 of LEDR Embedded Firmware
Release 5.0.0 contains the following versions of firmware:
#
#
Application:    5.0.0
DSP:            1.4.0
FPGA:           1.30
Modem Scripts:  1.45
Option FPGA:    1.66
Release Date:   10/13/2003
#	Please note that the upgrade instructions are contained at the end of 
# 	this document.
#
#
This software contains the following additions and modifications:

			NEW FEATURES:
		------------------------------
1) Protected Mode Changes:
   a. Radio A is the top unit and B is the bottom unit in a protected
      system (previously there was the concept of a "default" radio).
   b. Radio A will ALWAYS be active unless it is failed and B is good.
   c. Because of the last item, the concept of a forced switchover no
      longer applies.  A will always want to be the active radio.
      In order to provide the user the ability to test a particular
      radio in a protected system, a "protected mode" setting has been
      added so that the user can choose:  Radio A Only, Radio B Only,
      or Auto Switch.
   d. The A/B/Auto settings have been added to each of the interfaces.
      At the console, the "rdnt pmode [a | b | auto]" command.  At the
      front panel under the Redundant menu, the "Protected Mode" option
      has been added that supplies the options "A ONLY", "B ONLY", or "AUTO".
      At the web interface Protected screen and via the snmp agent, the
      "Protected Mode" options are "Auto Switch", "Radio A Only", and
      "Radio B Only".
   e. The Switch Xcvr option has been removed from all interfaces.

2) G.821 Changes:
   a. G.821 statistics are not reset when the modem becomes locked.
   b. The modem unlocked time is added to unavailable seconds.

3) Miscellaneous Changes:
   a. The previously tested fractional E1 changes for Aquila were merged
      into this release.
   b. Fixed a problem with the web server.  It sometimes returned a content
      length of 0 bytes and caused the browser to not display the html
      information.

			DEFECT FIXES:
		------------------------------
none.


			KNOWN ISSUES:
		------------------------------
1) Front panel may intermittently scroll menu when the network is heavily congested.   Work around by correcting network congestion issues.

2) "loopback outb" command does not work everytime due to intermittent 3rd party vendor hardware limitation.  Re - issue command again.

3) Warm Standby alarms. In Warm Standby mode, occasional demodulator acquisition 
   alarms occur. Although this does not affect data performance, MDS suggests 
   operating protected systems in Hot Standby.

4) "Reprogram Network" sometimes fail with protected system.   Work around by configuring radio to standalone and remove redundant cable.

5) Warm Standby is not fully functional.

6) !!! NOTE !!!
   An upgrade to this version of software from a previous version will cause
   the existing radio EVMAP settings to be reset to their default values.
   If the settings have been modified from their defaults, the mapping can
   be stored and retrieved using the EVMAP command and a computer running
   the ledr tftp application.

1) Fixed intermittent Redundant switching, especially when booting up from cold.

2) Fixed protected switching when performing "rfout" adjustment.

			KNOWN ISSUES:
		------------------------------
1) Front panel may intermittently scroll menu when the network is heavily congested.   Work around by correcting network congestion issues.

2) "loopback outb" command does not work everytime due to intermittent 3rd party vendor hardware limitation.  Re - issue command again.

3) Warm Standby alarms. In Warm Standby mode, occasional demodulator acquisition 
   alarms occur. Although this does not affect data performance, MDS suggests 
   operating protected systems in Hot Standby.

4) "RDNT SWXCVR" cannot be used until radio is powered-up for 2 minutes, after the protected system is fully initialized.  Or it may not switch.

5) "Reprogram Network" sometimes fail with protected system.   Work around by configuring radio to standalone and remove redundant cable.

6) Warm Standby is not fully functional.

Release notes for version 4.4.0 of LEDR Embedded Firmware
Release 4.4.0 contains the following versions of firmware:
#
#
Application:    4.4.0
DSP:            1.4.0
FPGA:           1.30
Modem Scripts:  1.45
Option FPGA:    1.66
Release Date:   08/15/2002
#	Please note that the upgrade instructions are contained at the end of 
# 	this document.
#
#
This software contains the following additions and modifications:

			NEW FEATURES:
		------------------------------
1) Added orderwire alert event - Order wire alert is now logged as an event, so it can be mapped to an external alarm or remote alarm for operator convienience.   Event is added to SNMP MIB also.

2) Added DTMF enable/disable feature - this can be used to disable DTMF when in noisy environment and DTMF function is not required.

3) Added "event init savemap" to re-initialize without resetting events map.

4) Added event to log Protected Link switching activities - added RDNT_ACTIVE event which is a pulsed event that is set when the radio goes active and cleared when it goes inactive.  Event is added to SNMP MIB also.

5) ARP Table now saved in Config File in format ARP_ENTRIES[index]=ip.  When sending, ARP_ENTRIES[0]=0.0.0.0 is sent if no config arp table entries.  When getting, ARP_ENTRIES[0] will trigger all  arp table entries to be flushed from the config data.

6) Added Network Table to MIB - added to the commonledr MIB: ledrNetworkTable and ledrNetworkTableEntry objects with ledrNetTabUnitID, ledrNetTabIPAddr, ledrNetTabRFHops, ledrNetTabEthHops, and ledrNetTabPort table entries.  

7) Added reprogram status to MIB - added to the commonledr MIB: new ledrFwProgStatus leaf under ledrFirmware object.  4 supported values: not started, in progress, complete failed, verify failed, complete ok.  

8) Added DIA530 RTS and DTR  setting to "Config" command so it can be saved to configuration file.

9) Added access priviledge to SUPER user to use "interface -o" command.

10) Added default configuration support via "model" command for mds700S and mds700F.

11) Added evmapping to config data for NV RAM Storage

12) BERT command overrides AIS conditions.

13) Added ledrRssiNumeric leaf object (Integer) to LedrPerformance object in commonledr MIB so that the RSSI value can be trended from SNMP manager.

14) Changed ENGR and FACT passwords to eliminate potential security issues.



			DEFECT FIXES:
		------------------------------
1) Fixed problems associated with Radio disappering from NET, NSD stops, and network services hung.

2) Fixed problem associated with SNMP Request for Alarm LED Status generating AlarmTrap.

3) Fixed FE1  C6 +CAS issue - The radios did not pass SA bytes transparently, even in fstruct mode 8. Sometimes they do pass the SA bytes, but stop doing so after a period of time, and even a reboot usually does not restore proper SA byte operation.

4) Improve DTMF detection reliability - reduced False DTMF detection to eliminate unwanted network traffic.

5) Fixed issue with Alarm output initialized to open when active open - enter "alarm out all active open" command then "events init" command.  Notice ouput alarms report false alarm conditions because they are initialized to open.  

6) Corrected spelling errors (Satellite, etc...).

7) Fixed problems associated with RF loopback when AIS is on and remote radio is generating AIS.  RF loopback overrides AIS conditions.

8) Modified 1400 PLL mising and spurs schemes to boost RF performance.

9) Fixed problems associated with E1 BERT & CAS framing.

10) Fixed problems associated with "Config send" from the far end of an E1 link.

11) Fixed problems associated with "Conifg getAll" not restoring correctly - save restore RxPllIfLo setting.  Notes:   Old config file should put "PLL_1400_RX_IF_LO=Off" or "PLL_1400_RX_IF_LO=On" right after "RADIO_MODEL=" line.

12) Fixed problems associated with Protected Radio Switch Over From Radio With <0 dBm.

13) Fixed problems associated with SNMP ledrSpanMapping MIB object returning genErr when SETTING.

14) Fixed problems associated with clearing FEC using Web interface.

15) Fixed problems associated with Data Service Channel transparency - Added  "transparent" subcommand to "svch" command (Also added service channel parameters  to config file / config manager).  This feature allow "ESC" to be filtered or not according to user re-programmable setting.

16) Fixed problems associated with No NSD over protected system.

17) Fixed problems associated with protected link not generating Tx Alarm when Tx power drops.

18) Fixed problems associated with routes in config data being incorrectly stored/displayed

19) Fixed problems associated with TMD pin assertion at remote radio when in loopback remote mode.


			KNOWN ISSUES:
		------------------------------
1) Front panel may intermittently scroll menu when the network is heavily congested.   Work around by correcting network congestion issues.

2) "loopback outb" command does not work everytime due to intermittent 3rd party vendor hardware limitation.  Re - issue command again.

3) Warm Standby alarms. In Warm Standby mode, occasional demodulator acquisition 
   alarms occur. Although this does not affect data performance, MDS suggests 
   operating protected systems in Hot Standby.

4) "RDNT SWXCVR" cannot be used until radio is powered-up for 2 minutes, after the protected system is fully initialized.  Or it may not switch.

5) "Reprogram Network" sometimes fail with protected system.   Work around by configuring radio to standalone and remove redundant cable.

#
#
This software contains the following additions and modifications:

			NEW FEATURES:
		------------------------------
1)  Customer Data Service channel support has been added.  The customer data service
    channel port (located on the rear panel) provides broadcast ASCII data
    transmission. 
2)  Full-rate radios are now defaulted to unframed mode in 1, 2 and 4E1 (i.e. fstruct 
    mode 8). Unframed E1 causes the radio to treat the input data stream transparently.  
    That is, it makes no attempt to recover frame alignment.  Therefore, line error 
    counting will only record linecode violations detected.  Note that in both the 
    framed and unframed cases, the radio only monitors the framing, and makes no 
    changes to the data.
3)  2xE1 support has been added.
4)  Proxy ARP has been added to the radio to ease routing configurations of
    external IP and NMS equipment.  The "gateway" radio will proxy ARP for all
    radios which are located over-the-air from the radio's ethernet network.
    The "arp" commmand has been added to allow the user to add additional host IP
    addresses for which to proxy.  This is useful when a device, such as a
    mux, is located at the end of a string of radios.
5)  User login and logouts are recorded in the event log.
6)  Added "rfout actual", "rfout offset", and "rssi offset" commands to allow simple
    adjustment of the RF output and RSSI calibrations.
7)  Configuration file upload/download can be performed through the console
    port.
8)  Modem setting 64kbps/32QAM has been enabled.
9)  The owner string is passed amongst the radios and shows up in the network
    table (accessed using the "network" command).  This can be useful in
    identifying radios in the network.  Note that this feature can be
    enabled/disabled using the "network owner" command.
10) IP masquerading has been added to the protected version of the radio so
    that when a "gateway" radio fails or is removed, the sibling radio will
    forward IP packets in its place.  Note that this feature can be
    enabled/disabled using the "rdnt nsd" command.
11) The "events filter" command has been expanded to ease disabling events for
    unused E1 lines.
12) The "eia530 rts" command has been added to enable/disable RTS at the
    EIA-530 port.  Also, the "dtr" command has been moved to be a subcommand under
    the "eia530" command.
13) The functionality of the ACTIVE LED on the front panel has changed for
    non-protected radios.  When the radio is actively transmitting the ACTIVE
    LED will be illuminated.
15) The USER_RDNT_SWITCH event is logged when a user forces a transceiver
    switch on a protected radio.
16) The interleave depth is now accessible in the commonledr MIB.
17) The carrier offset is now accessible in the commonledr MIB.
18) The "all" subcommand has been added to the "trapfilter" command.
19) The "rfout pad" command has been added to allow an attenuator to be added
    to the transmit path and have the radio report an RF output power which is
    lowered by the attenuator value.


			DEFECT FIXES:
		------------------------------
1)  The "telnetd" command now reports all telnet sessions correctly.
    Previously, if two telent sessions were connected and the first session
    was terminated, "telnetd" would report no sessions connected. 
2)  Setting the interface type to current mode no longer causes loss of link.
3)  The DUPLICATE_ID event now clears when the condition ceases. 
4)  The fan status affects the protected status.  
5)  The "iverify" command detects a missing option FPGA image.  
6)  The "!" history command has been restricted from access in telnet
    sessions.
7)  The outbound ping command formerly failed occasionally.  This has been fixed.

			KNOWN ISSUES:
		------------------------------
1)  DO NOT use SNMP Telnet detection polling.
2)  Upgrading from version 1.4.0 to version 2.2.1 to version 2.4.0 will cause
    the external alarm names to be reset to their default values.  
3)  The E1/T1 linenames are restricted to 15 characters or less.  
4)  Running version 2.3.1 and version 2.4.0 on radios in the same network
    with owner string passing enabled ("network owner on" command) causes networking
    problems.  Notably the network table ("network" command) will consistently
    change and rlogin will be unstable.  
5)  SNMP does not properly indicate when a radio is in server-remote loopback mode. 
6)  Using the "all" selection for the self test initiation from SNMP does not
    work.  
7)  The clock mode table in the Framed E1/T1 MIB should be removed since it 
    can not be retrieved.  
8)  Unkeying the radio from SNMP may cause a response timeout at the SNMP
    manager.  The ramp down time may exceed the manager's timeout.  The
    timeout can be increased or the error may be ignored.

This software contains the following additions and modifications:

			NEW FEATURES:
			------------------------------
1)  Configuration file upload/download via TFTP.
2)  Configuration file upload/download and event log file upload can be 
	performed from SNMP.	
3)  The alarm inputs and outputs can be named.  16 characters per alarm 
	name.  
4)  A timeout can be specified for network reprogramming using TFTP.  
5)  Warm-standby is supported for protected radios.  
6)  G.821 monitoring for full-rate.  
7)  Alarm inputs are triggered on programmable logic levels.  
8)  Protected transceiver switch can be commanded from either radio.  
9)  The front panel LCD backlight can be turned on and off.  
10) The "boot -o" command was added to reboot to the other image.  
11) The "rdnt" command indicates when the radio is not connected to the
	switching chassis.  
12) Support for warm-standby has been added to the redundant MIB.  
13) The "trapfilter all" command has been added to add all trap types.  
14) 4E1 is now supported in all versions of the full-rate radio.


			DEFECT FIXES:
			------------------------------
1)  The front panel updates when console baud rate is changed.  
2)  Front panel loopback handles E1/T1.  
3)  Continuous prompting at the console has been fixed by handling characters 
	one at a time.	
4)  Fractional/T1/E1 commands have been filtered dependent on interface
	configuration.  
5)  "ver frw" subcommand has been removed.  
6)  Trap sent to invalid IP address no longer prints asynchronous message.
	
7)  "trend" from rlogin no longer puts console in "garble mode".  
8)  "icopy" checks for invalid arguments.  
9)  Menus have been reworked for full-rate configuration and reporting
	including: data interface, select line "all" removed, reframe criteria,
	and loopback local.  
10) "log" command handles invalid arguments.  
11) "modem" command displays everything in kbps.  
12) Events trigger only the specified alarm outputs.  
13) SNMP ledrRedundantInfo.XcvrActive reports TRUE for standalone radio.  
14) SNMP ledrLineInterface is read-only.  
15) Remote radio's AIS does not get stuck when turning off remote loop at
	local radio.  
16) IP address of 0.0.0.0 received from NSD is ignored, no longer causing
	reboots.  
17) Fullrate types removed from subrate loopback object in SNMP.  
18) If a protected radio powers up failed, the event is logged.  
19) The temperature threshold causes a performance degradation event.  
20) BERT is functional.  
22) "evmap" command allows more than one LED or alarm output to be mapped. 

			KNOWN ISSUES:
			------------------------------
1)  Data Service channel is not yet implemented.
2)  If the SCSI cable is removed from a protected unit, the status and active
    indications may be incorrect.  
3)  The RDNT_SWITCH event is not being logged on protected units.  
4)  A 16 character linename causes problems in SNMP.  
5)  If the active radio of a protected chassis has a loss of signal it will
    generate AIS even if the other receiver is still locked.  To avoid this
	problem, disable AIS generation when hitless switching is enabled.
6)  The alarm input and output contact settings can be changed by a read-only
    user.  
7)  If the alarm output active state is set to "open", the alarm output is
    still closed when an event is generated.  
8)  If a string of more than 40 characters is sent to the console using a
    computer scripting application (such as a ProComm Plus macro), the
	40th character will be lost.  
9)  If the radio can not go into "loopback remote" mode, it does not provide
	an error message.
9)  Some defects remain from 2.2.0 - see 2.2.0 and 2.1.0 release notes below

Release notes for version 2.1.0 of LEDR Embedded Firmware
Release 2.1.0 contains the following versions of firmware:
#
#
Application:    2.1.0
DSP:            1.1.0
FPGA:           1.17
Modem Scripts:  1.38
Option FPGA:	1.46
Release Date:   02/17/2000
#
#
##### NEW FEATURES
#
This firmware has the following new features:
1) Support for Fractional T1 in the LEDR 900S1.
2) Support for a single E1 full-rate for the LEDR 1400F and 400F.
3) Support for redundant hot standby for the LEDR 900S and LEDR 1400F.
4) The SNMP MIB was completely restructured to allow for extensibility and flexibility.
   The MIB now consists of 5 files which are based upon the common, full-rate/fractional,
   redundant and subrate objects.  Users only need include the mib files that correspond
   to their version of the LEDR radio.
5) Added an outgoing ping command to the console port commands.
6) Added the ability to read the state of the alarm inputs and outputs using the
   alarm command.
7) Added Support for the LEDR 1400 and LEDR 400
8) The "status" command has been added which provides the tx and rx frequencies, bandwidth, 
   data rate, modulation type, interleave depth, clock mode, RSSI, SNR, RxLock state, RF output 
   power, txkey state, PA temperature, IP address, IP netmask, and IP gateway.
9) If the time/date have not been set, a message is displayed on power-up to let the
   user know to program them.
10) Configuration data will be maintained for upgrades from ALL previous versions
    of software.  Previously, it was maintained only 1 version back.
11) The event number is sent first in all SNMP traps.
12) Added an option for loopback time out.
#
#
##### Modifications and Fixes
#
This software contains the following additions and modifications:
1) When firmware was upgraded to version 1.4.0 (as opposed to a brand new radio),
   the configuration data self-test occasionally failed - Fixed
2) The hardware was modified to remove the ability to read the internal voltage
   of the radio, therefore the voltage object was removed from the MIB - Fixed 
3) Users were incorrectly logged out of the console port while utilizing the console
   menus after ten minutes - Fixed 
4) Changed logout command for rlogin from "bye" to "logout" 
5) "passwd" command from telnet should not be allowed since password changes should
   only be allowed via SNMP or local console connection for security reasons - Fixed
6) Users were incorrectly allowed to execute the BIT Test from the fron panel when not 
   logged in - Fixed 
7) IP Netmask, Gateway and Port occasionally did not get set properly. Users must
   now reboot on all IP changes (similar to a PC) - Fixed TR#440
8) SNR reports invalid number when modem is unlocked - Make it report 0 dB - Fixed
   TR#257
9) Rfout displayed as whole dbM target power if within spec - Fixed TR#417
10) Fixed orderwire "alert all" - Fixed TR#407
11) Disallow multiple reprogram sessions - Fixed TR#377
12) Front panel power out displayed improperly when unit unkeyed - Fixed TR#480
13) Rlogin sessions now properly timed out after 10 minutes - Fixed TR#498
14) Placing unit from local loopback directly to remote loopback did not
    work properly, needed to go thru loopback none to get it to work. Fixed TR#488
15) Added commands for Admin (SUPER) user - alarm, pmmode, rfocal and rssical for
    system alignment and tuning - Fixed TR#419
16) Unit ID has been changed to be read-only in the common LEDR MIB.
#
#
##### Errata and known defects
#
This software contains the following known errata:
1) Duplicate Unit ID detected alarm does not properly clear
2) In "route print" command, netmask is occasionally displayed as 0.0.0.0 when
   it is actually set correctly.
3) SNMPc displays garbage characters or UNK for write only objects - This is a
   known limitation of the SNMPc 4.2 MIB Browser!
4) Unkeying the radio should more gracefully ramp power down.
5) In 1400, the transmitter should be unkeyed if any of the pll's go out of lock
   (not just the txpll).
6) The front panel does not update the baud rate of the console port if changed
   from another user interface (like console, telnet, etc...)
7) The Loopback console menus do not support E1/T1 loopback modes.
8) T1 ESF outbound loopback not supported in SNMP.
9) Pinging a local radio takes approximately 40 milliseconds.  It could be
    faster.
10) G.821 Performance monitoring is not yet implemented for individual 
    Fractional T1 or E1 line interfaces, it exists on the RF link only.
11) Radio redundant status may get confused when the cable from the radio to
    the protected chassis is removed.  The correct radio will be active, however.
12) The redundant switch command does not work properly and is disabled.  To execute
    a manual switch, users should unkey the active radio.  The switch will occur
    provided that the inactive radio is not already in a failed state.
13) Loopback via SNMP does not work.  Suggest using telnet.
14) If IP address and netmask are set to 0.0.0.0, the remote radio may reboot
    itself.  Do not set IP address to 0.0.0.0.
15) Executing the trend command from rlogin may cause the rlogin session to lock-up.
    This clears itself in 10 minutes when the session times out.  It shows up as 
    garbled characters at the console port on the remote radio.
16) This software does not presently support Warm Standby.
17) This software does not yet support an SNMP alarm naming table.
18) The line error reporting from the console menu does not show any data, it
    only allows enabling or disabling.
19) Serial Reprogramming from the Flash Utility may rarely stop programming
    after a sub-section of the image.  Restart the programming process either from
    where it left off or all over again.
20) If a computer sends down a command line to the console over 40 characters,
    every 40th character is missed.

#####               TFTP Firmware Upgrade Notes                            #####
################################################################################
#
TFTP Software Upgrade instructions:

Software Upgrade via TFTP (may be local or over the air):

      Note:  This process may take up to 30 minutes when using the embedded 
             service channel of the LEDR Radio for IP traffic.
     

- Copy the file ledr.mpk into a known directory (for example c:\windows\temp\)

- Launch a TFTP server on a PC connected either directly or via a LAN (or over 
  the air) to the ethernet port of the LEDR Radio.

- Obtain and document the TFTP server PC IP address (For example 192.168.1.2).

- Point the TFTP server to the directory from which you desire to upload the 
  new software.  In the SNMPc TFTP server, you should execute the "set root" 
  command and point to the known directory where ledr.mpk has been copied. 
  (For example set root to c:\windows\temp\)

- Telnet and login (or remote login via "rlogin") to the radio which you desire
  to reprogram.

- Verify the active image from which you are currently executing by typing 
  "boot".  The software will be programmed into the inactive image.

- Execute the command "reprogram network ledr.mpk [IP address]".  In the 
  command, in place of [IP address], you should actually type the IP address 
  of the TFTP server.  For example, "reprogram network ledr.mpk 192.168.1.2"

- If desired, the status of the transfer during reprogramming may be displayed
  by typing "reprogram status".

- The TFTP Server and radio will notify you when the programming is complete.

- Verify which image area has been programmed by typing "ver ext".  The 
  inactive area will show new Software version.

- Reboot the software by typing the command "boot 1 or boot 2", depending upon 
  which image has the newly programmed software.

- If desired, upon testing of the new firmware, reprogram the other image by 
  typing "icopy"
