ES-2810 ATM Uplink Module User Guide 1 - 1
CHAPTER 1
Introduction
This chapter describes the ATM-1/155 ATM Uplink Module, which is an optional
component that can be installed in an ES-2810 Ethernet Switch. The module pro-
vides a data bridge between Ethernet and ATM ELANs.
There are three types of ATM Uplink Modules available:
• 155 Mbps OC-3c/STM-1 multi-mode
• 155 Mbps OC-3c/STM-1 single-mode
• 155 Mbps OC-3c/STM-1 UTP

NOTE
For technical specifications, see Appendix A
on page A-1.
To differentiate the ATM Uplink Module from other modules used in the ES-2810
(Stack Interface Modules, Matrix Modules, etc), this manual refers to the ATM
Uplink Modules as ATM Modules.
NOTE
For information on the ES-2810 Ethernet
Switch, see the ES-2810 Ethernet Switch User’s
Manual.
1.1 Modes of Operation
The ATM Module can operate in two modes:
• Stand-alone mode: Used to provide a data bridge between a single
ES-2810 and an ATM switch on an ATM ELAN.
• Stack mode (default): Used to provide a data bridge between a
stack of ES-2810s (two or more switches) connected by a Matrix
Module and an ATM switch on an ATM ELAN.
