Overview
Welcome to Allied Telesyn International!
Allied Telesyn’s 
AT-4016TR Ethernet Switch With ATM Access
, 
AT-4016F 
Ethernet Switch With ATM Access 
and 
AT-TS95TR TurboStack Switch With 
ATM Access and Management
 are all Ethernet-to-Ethernet and Ethernet-
to-ATM switches. All support 10 Mbps of 
dedicated
 bandwidth on 16 
(AT-4016TR and AT-4016F) or 8 (AT-TS95TR) IEEE 802.3 Ethernet ports. 
Further, all support a 155 Mbps Asynchronous Transfer Mode (ATM) port for 
connectivity to an ATM switch.
The release of system software Version 2.4 (or greater) supports bridging 
between Ethernet and ATM using Switched Virtual Circuits (SVCs). Besides 
bridging, your switch provides an Emulated LAN (ELAN) capability which, 
using (or not using) an optional 
LAN Emulation Configuration Server 
(LECS)
, allows you to group all Ethernet devices in your switch — as well as 
additional switches — as if you are in the same physical LAN.
As stated in the Preface, all switches are almost identical in form and 
function. The differences are primarily physical. The following table 
summarizes these differences.
