Overview: BXM Cards
Figure 5-1
A BPX Switch Network with BXM Cards
BXM cards are compliant with ATM Forum UNI 3.1 and Traffic Management 4.0 specifications
including Available Bit Rate (ABR) VS/VD. These cards provide the capacity to meet the needs of
emerging bandwidth driven applications.
The types of BXM cards are regular and enhanced. The enhanced BXM cards (also called BXM-E)
improve upon the regular BXM cards by delivering more cost-effective ATM switching and traffic
management and support a higher connection density on certain models. Throughout this document,
BXM is used to denote either the regular BXM or BXM-E. Specific BXM-E models are denoted with
suffix D, DX, E, or EX.
The BXM cards are designed to support the following service classes:
•
Constant Bit Rate (CBR)
•
Real time and nonreal time Variable Bit Rate (rt-VBR and nrt-VBR)
•
ABR with VS/VD
•
ABR without VS/VD
•
ABR with VS/VD supports Explicit Rate Marking and Congestion Indication (CI) control.
•
ABR using ForeSight
•
Unspecified Bit Rate (UBR).
All software and administration firmware for the BXM card is downloadable from the BCC and is
operated by the BXM on-board sub-system processor.
The following are the types of front and back cards used for the BXM card set:
•
The BXM T3/E3 is available with a universal BPX-T3/E3 back card in 8 or 12 port versions.
•
The BXM-OC-3 is available with 4 or 8 port multi-mode fiber (MMF), single mode fiber (SMF), or
single mode fiber long reach (SMFLR) back cards.
•
The BXM-OC-12 is available with 1 or 2 port SMF or SMFLR back cards.
Any of the twelve general purpose slots in a BPX are used for the BXM cards. The same back cards are
used whether the BXM ports are configured as trunks or ports. Table 5-1 and Table 5-2 list the available
front and back card options for the BXM-T3/E3, BXM-155, and BXM-622.
