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).
