BPX Switch Common Core Group
The BPX switch Common Core group includes the Broadband Controller Card (BCC-3 and
associated BCC-3-bc backcard, or BCC-32 and associated BCC-b backcard), or BCC-4 and
associated BCC-3-c backcard, the Alarm/Status Monitor (ASM), a Line Module for the ASM card
(LM-ASM), and the StrataBus backplane (see Figure 3-1). The BCC-3 and BCC-32 are functionally
equivalent and support 9.6 Gbps operation, but use different backcards. The BCC-4 supports the
19.2 Gbps operation of the BXM cards and provides 32M or 64M.
