Release notes for version 2.4.0 of LEDR Embedded Firmware
Release 2.4.0 contains the following versions of firmware:
#
#
Application:    2.4.0

FPGA:           1.21

Release Date:   07/10/2000
#
#	Please note that the upgrade instructions are contained at the end of

#
#
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.

	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.

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

#
#
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.

             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"
