ZyXEL Communications omni.net LCD+M User Manual

11-1 

This chapter describes how to upgrade the flash EPROM firmware of your omni.net when a new 

version is available. 

 

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).
