Key Features
• High-scalability connection densities with up to 144 T3/E3
ATM ports on a single Cisco BPX
wide-area switch
• Complete network control through dynamic resource sharing
and support for all ATM service classes
• Industry's first fully compliant ATM Forum available bit rate
(ABR) virtual source/virtual destination (VS/VD) capability in
custom ASICs
• New level of ATM price/performance to optimize the network
life cycle
• Support for VC merging with future software upgrade allows
"label" sharing for different MPLS VCs with the same
destination and class of service (enhanced -E and -EX
models only)
With the increasing deployment of Asynchronous Transfer Mode
(ATM) networks, there is a growing need for an ATM network
platform that can deliver an unprecedented level of scalability,
performance, and functionality at lower costs. Such an ATM
switching platform must support high-speed interfaces with high
port densities as well as advanced ATM traffic management
capability.
Advanced ATM traffic management capabilities are
implemented in a family of custom ASICs that enable
high-density, high-speed ATM interface modules with advanced
features and functionality for the BPX 8600 and IGX
series wide-area switches.
This ASIC technology cost-effectively delivers the most
advanced ATM switching and traffic management capability in
the industry. It represents the first commercially available
implementation of VS/VD.

NETWORKS
The BXM-T3/E3 broadband switch module is a 8-, or 12-
port, Digital Signal level 3 (DS-3) (45 or 34 Mbps) ATM interface
card for the BPX switch platform. The interface can be configured
for trunk, public, or private User-Network Interface (UNI)
applications on a per-port basis to provide a high-density,
low-cost broadband ATM networking solution.
