About the Passport 8672ATME Module

The Passport 8672ATME Module provides network transmission using ATM technology. The Passport 8672ATME Module enables MAN/WAN/campus connectivity for the Passport 8600 Routing Switch with the capability to interconnect frame-switched networks using a backbone ATM network. The module also provides existing ATM customers with the capability for connectivity to the Passport 8600 Routing Switch. (For more information on ATM, refer to the ATM Forum Web site at the http://www.atmforum.com URL.)

The Passport 8672ATME Module occupies a single slot in a Passport 8600 series chassis. The module is a baseboard with room for two of the following optional Media dependent adapters (MDAs):

•1-port OC-12c/STM-4: single-mode fiber (SMF) or multimode fiber (MMF) using the Synchronous Optical Network (SONET/SDH) media

•4-port OC-3c/STM-1: SMF or MMF using SONET/SDH media

The Passport 8672ATME Module for the Passport 8000 series chassis can be used as an edge device for WAN connectivity in the data center; it is used to connect Passport 8600 to public or private ATM networks. You can also use the Passport 8672ATME Module in the wiring closet in inter-building connection technology in campus networks where each building is supported by frame-switched networks.

Another network application of the Passport 8672ATME Module is a direct connection between one Passport 8600 series switch with a Passport 8672ATME Module in one building to an identical module in another Passport 8600 Series switch at another building. You connect the switches with a dedicated fiber link or with a SONET multiplex network. Each building may be individually supported by either frame-switched or ATM technology.
