Firmware Upgrade
This chapter describes how to upgrade the flash EPROM firmware of your omni.net when a new
version is available.
Upgrading with Flash EPROM
Your omni.net ISDN TA employs a flash EEPROM (Electronic Erasable Programmable Read
Only Memory) that lets you conveniently update firmware and program the ISDN TA with new
features and enhanced functions.
If you use a Windows operating system, run the ZyXEL ISDN Configuration Manager to upgrade
new firmware. For other Operating Systems, use a terminal program that supports the X-modem
protocol.
Obtain the new firmware from ZyXEL's BBS, WWW, or FTP site. See Contacting ZyXEL for
more information. The firmware is distributed with the file name (your model) d.vvv, where the
extension 'vvv' denotes the version of this firmware. The modifier 'd' in the filename has the
following definitions:
!
d = E - European ISDN (DSS1), also used in most other countries including Asian
countries.
!
d = A - American ISDN (AT&T 5ESS, Northern Telecom DMS-100, or National
ISDN-1, the active D-channel protocol can be chosen by an AT command).
