Dear customer,                                       Vienna, July 12th 1996



After uncompressing the file E2864IE2.Z03, which has been compressed using
the PKZIP v2.04g, you will find following files:

-----------------------------------------------------------------------------
 E2864IE.203   v2.03 for Elite 2864I ISDN, EuroISDN "DSS1" D-channel protocol
 EI203_QR.TXT  Quick Reference Guide as ASCII text file
 EI203_RN.TXT  Release Notes (for ISDN firmware v2.03) as ASCII text file
 E_112DRN.TXT  Release Notes (for MODEM firmware v1.12d) as ASCII text file
 PPP_MP.TXT    description of channel bundeling PPP as ASCII text file
 PPP_MP.RTF    description of channel bundeling PPP as Rich Text Format file
-----------------------------------------------------------------------------




Please start the "XMODEM with CHECKSUM" firmware upload procedure on
your ZyXEL Elite modem with the command "ATUPX" and wait till the modem
tells you to start the programming. Then use any terminal software with
"XMOMDEM with CHECKSUM" (not CRC !) and upload the plain binary firmware:
We recommend to use Telix, ProComm plus, Terminate, Telemate,
HyperTerminal/95 or ZyXEL's ZFAX v4.0x, which is delivered together with
the ZyXEL Elite modem.

Note: choose the maximum DTE rate which your terminal software offers
(eg: 115200 bps) to upload the binary firmware file !
Because in earlier days some customers asked how long the upload will last
here are some time schedules:
Telix/DOS v3.50  with DTE speed 115200 bps:   4 minutes  (about  5000 cps)
                 with DTE speed 230400 bps:   2 minutes  (about 10000 cps)
                 with DTE speed 460800 bps:  50 seconds  (about 20000 cps)
PS: The 2x or 4x DTE speed is not a feature by Telix/DOS. It results if you
    use a highspeed serial I/O card (such like ZyXEL's "SP111AT" or
    ZyXEL's "2S1P") with DTE-speed multiplier function (2x or 4x clocked
    UART chip 16C550)


Please have a look to the firmware release notes of the analog Elite
modem (V.34 only) too because these features have also been implemented
in the ISDN modem's internal Fax/Modem/Voice device !
    EI203_RN.TXT ....  ISDN  firmware release notes, v0.01 -> v2.03
    E_112DRN.TXT ....  MODEM firmware release notes, v0.01 -> v1.12d



==========================================================================
ATTENTION:
  After uploading the new firmware into Elite's Flash-EPROM I recommend
  to do a "factory/hardware-reset": while powering on the Elite modem
  push the "D/V" button (Data/Voice = upper button) on hold this button
  for about 5 seconds, then release this button. Maybe you will receive
  strange characters on the screen of your terminal software then. These
  are the test patterns which are sent with 115200 bps from Elite to your
  DTE. This is an endless test - power off and on again your modem.
  All internal tables (phone numbers, passwords, calling party numbers,
  protocol specific called party numbers) will be erased also !
