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-S13 PCMCIA 
Firmware Card (Version 2.4) and the 
AT-TS95TR TurboStack Switch With 
ATM Access and Management
 which uses the optional AT-S16 
Firmware 
Cassette 
(Version 2.4).
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.”
We have included the latest available information on ATM Forum UNI 3.0, 
Switched Virtual Circuits, Q.2931 Signaling and ATM Forum LANE 
Specification 1.0.
On the other hand, standards for electronic networks in general, and ATM 
standards 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.
Additionally, since you will be implementing LAN Emulation, additional 
equipment and software must be purchased separately. That is, this software 
has been engineered to work in conjunction with LANE services. The 
features of this switch will not be entirely functional without it.
