Chapter 5 BXM Card Sets: T3/E3, 155, and 622
Enhanced BXM
Enhanced BXM
The Enhanced BXM cards improve the current BXM cards by delivering even more cost-effective ATM
switching and traffic management. The Enhanced BXM cards come in EX and DX versions, both
including these key feature enhancements:
•
Support a greater cell storage capacity and a greater number of connections
–
The cell memory has been increased on the Enhanced BXM cards to support even greater cell
buffering to maximize bandwidth efficiency and cell/frame throughput in wide area networks.
–
Enhanced BXM cards support up to 12 ATM interfaces per card at speeds from T3/E3 to
OC-12/STM-4.
–
The ACP processor memory is quadrupled
ACP Processor memory is 64 Mbyte and the flash memory is doubled to 4 Mbyte on all
Enhanced BXM cards to allow more headroom for feature addition and enhancement in the
future.
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 ever increasing demand for
greater number of connections per interface. For each PVC terminating on the card, Enhanced
BXM supports a full range of stats for usage-based billing at cell and frame levels, cell policing,
EFCI marking, ABR RM cells, and OAM cells. Supporting a greater number of connections per
interface translates to supporting a greater user density more cost effectively.
This table provides detailed information about the number of connections and cell buffer size
supported on different types of Enhanced BXM card:
•
Support an improved traffic shaping granularity for each virtual interface (VI) to allow any desired
shaping rate.
