Operation Manual

Preface
Background
This document represents a discussion of the software operating systems of 
Allied Telesyn International’s (ATI’s) 
AT-4016TR (or AT-4016F) Ethernet 
Switch With ATM Access 
which uses the optional AT-S7 PCMCIA Firmware 
Card (Version 2.0) and the 
AT-TS95TR TurboStack Switch With ATM Access 
and Management
 which uses the optional AT-S9 
Firmware Cassette 
(Version 2.0).
This manual assumes that you, the user, are familiar with the fundamentals of 
Asynchronous Transfer Mode (ATM) technology as well as the operation of 
Ethernet switches. 
If you are unsure about some of the features included in this document, we 
refer you to the reference documentation noted in this preface under the 
subheading “Related Documentation.”
As you are probably aware, the standards for electronic networks in general, 
and ATM technology in particular, are in transition. They have changed. They 
are presently changing. They will certainly change in the immediate future. 
In short, while our criteria is valid as of the date of this publication, this arena 
of technology is so dynamic that you are cautioned to seek other sources for 
the latest standards.
