Optional Slide-In Modules

Option modules provide alternate downlinks for the Switch 2000 TR.

NOTE: Be sure the ﬁller plate cover is installed when the module slot is not occupied.

Slide-in modules are available for the following:

The ATM Module

The SuperStack II Switch TR ATM OC-3 module pro- vides a high-speed ATM connection between the Switch 2000 TR and ATM networks. When positioned in workgroup or departmental LANs, the ATM down- link module offers a 155 Mbps data path to building, campus or ATM network backbones directly from the Switch 2000 TR. Perfect for providing cost-effective ATM access to smaller isolated LANs or bandwidth intensive and mission critical applications, the ATM downlink also provides a logical migration path for existing Token Ring LANs to mainstream high-speed networking technologies.

Redundant links can protect your Switch 2000 TR from network failure or equipment inconsistencies. The built-in Software Upgrade feature allows you to download software revisions easily.

Beneﬁts of an ATM

ATM is the only computer networking technology designed to carry video, voice and data trafﬁc simul- taneously. ATM provides the level of service necessary
