Enhanced BXM
The Enhanced BXM (BXM-E) cards improve the current BXM cards by delivering even more
cost-effective ATM switching and traffic management. The Enhanced BXM cards come in D, E, DX and
EX versions, both including the following key feature enhancements:
•
Support a greater cell storage capacity and VC configuration memory
–
The cell memory is increased on the Enhanced BXM cards to support even greater cell buffering
to maximize bandwidth efficiency and cell/frame throughput in wide area networks.
–
The ACP processor memory is quadrupled
ACP Processor memory is 64 MB and the flash memory is doubled to 4 MB on all Enhanced
BXM cards to allow more headroom for feature addition and enhancement in the future.
•
Support a greater number of connections
With a more powerful processor and more VC configuration memory in ATM cell switching
subsystem, the EX and DX versions of Enhanced BXM cards meet the increasing demand for greater
number of connections per interface. BXM-E cards support a greater number of connections per
interface, which cost effectively translates into supporting a greater user density.
