1. Fixed problems and new features
----------------------------------

New Features 
	- Y2K conformity for ITK MPR 3.1 and RAR 4000
	- NetWare 5 support for active ISDN boards
	- enhanced accounting functionality
	- changed handling of backup files:
		if accounting file or trace file grows bigger than
		configured( MaxFileSize ), it's copied into the ETC
		directory and renamed to yymmdd.<ext> (same extension).
		If the volume space is getting low, the first file
		of the same kind will be overwritten. 
		The maximal number of backup files is user-definable in
		ix1cca.cfg (MaxBackupFiles).
	
Fixed Problems
	- add channel bundling mode: "Manual" for WAN-ODI
	- add PPP compression as parameter for WAN-ODI
	- correct handling of specially sized V.110/Modem packets
	- PPP IP Address assignment fixed (double or random IP addresses)
	- crash when editing outgoing dialnumber fixed
	- PPP MLP is now allowed for 2 Channels only
	- D64S activates all permanent connections if controller
		has been reloaded
	- log file start time (1.1970 0:00)
	- no counting of discarded packets in statistic


2. Installation
---------------

This Service Pack updates existing installations of ITK MPR 3.1,
ITK RAR 4000 and ITK NetBlazer 4400.

1) Copy the self extracting archive to the sys:nb4400 directory
   of you server.
2) Extract it by simply executing it.
3) Install the Service Pack from the server console by:
	"load install"
	choose "Install a new product".
	Press <F3> and specify the installation path: "SYS:NB4400"

4) after installation restart all components using the batch "connect.ncf"

If you get multiple Errors: 
"Loader cannot find public symbol: CMSMGet...."

refer to "3. Recommenced patch level for NetWare Servers"

So, if you should have any problems, back-up the old files and copy all
updates from the ODI33 directory (and subdirectories) into the
sys:system directory of your server.

5. Known problems
-----------------

The current ITK NB4400 implementation of SPX spoofing does not support SPX II.



6. NetWare 5.0
-----------------

If you are using the graphical console on the server, any process
on processor 0 is slowed down. The processor is working exclusively for the 
GUI can not be interrupted by other processes. This may cause the ISDN connection 
to lose packets, so that the performance is affected.

NetWare 5.0 Beta 3:
If you are using NetWare 5.0 Beta 3 there is a problem with the
Logo Screen. If the server loads the Logo-Screen while startup and
the ITK ISDN driver, the server will crash later if you try to work
with the ITK desktop. A work around is, not to display the Logo
screen while startup, by loading the server with the -nl switch not
to load the Logo Screen.

To load the server without displaying the logo type:
"server -nl"
at the dosprompt.



7. Support of ITK Octo
----------------------

The current version of the ISDN driver software is able to handle ITK Octo and
ITK Basic boards. Due to the fact that it is not possible to auto-detect
whether a ITK Basic is equipped with an Octo expansion card or not, you have to edit
the ix1.ini manually. Please refer to the ITK manual "Installation and interfaces".



8. Special Drivers for ITK Hardware
-----------------------------------

This Service Pack contains no firmware files for your active ITK ISDN controllers.
All firmware files delivered with your NetBlazer 4400 CD-ROM are still up-to-date.



9. Remarks concerning NLSP NetWare Link Service Protocol
--------------------------------------------------------

The NLSP routing protocol (IPX) is designed to reduce the traffic in large
internetworks by shortening the time of information distribution about network 
changes. For this purpose each router polls its "neighbor" every 20 seconds.
If no changes occur, the router will announce its routing information to EVERY
single NLSP router in the network every 120 minutes.

We suggest to use NLSP on LANs only. Therefore RIP/SAP routing should be used on
ISDN WAN links, instead.

How to switch off NLSP:

-> load inetcfg.nlm
-> select "Bindings"
-> select "IPX binding to board"
-> select "Expert Bind Options"
-> select "NLSP Bind options" 
-> change the NLSP State to "off"



10. Remarks concerning NetWare Management System
------------------------------------------------

If you are using the Novell NetWare Management System with an installed
NetExplorer on one or more server(s), this/these server(s) will continuously scan the
whole network. This is done by using IPX Diagnostic, IPX SNMP, SPX and NCP packets.
Due to the fact that SPX and NCP Packets are also used to exchange user data
an active NetExplorer will cause that the respective ISDN lines are brought up frequently !!
