Upgrading Your omni
This chapter describes how to upgrade flash EPROM firmware when
it is available.
Upgrading with Flash EPROM
Your TA employs a flash EEPROM (Electronic Erasable
Programmable Read Only Memory) that lets you conveniently
update firmware and program the TA with new features and
enhanced functions. If you use Windows, use the ZyXEL Internet
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 on page v for more information. The
firmware is distributed in a file (your model)d.vvv, where the
extension vvv denotes the version of this firmware. The modifier d in
the filename has the following definitions:
•
G - German national ISDN (1TR6).
•
E - European ISDN (DSS1), also used in most other countries
including Asian countries.
•
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).
O
NOTE
: The American firmware version supports both the S/T
interface and U interface models. During the power-on test, it
checks the hardware configuration and follows the initialization
procedures of the specific interface.
1. Make sure your TA is turned ON.
