Broadband Controller Card (BCC-32, BCC-3, BCC-4)
Broadband Controller Card (BCC-32, BCC-3, BCC-4)
The Broadband Controller Card is a microprocessor-based system controller and is used to control
the overall operation of the BPX switch. The controller card is a front card that is usually equipped
as a redundant pair. Slots number 7 and number 8 are reserved for the primary and secondary
(standby) broadband controller cards. Each broadband controller front card requires a corresponding
back card.
• For non-redundant nodes, a single BCC is used in front slot number 7 with its appropriate
backcard.
• For redundant nodes, a pair of BCCs of matching type, are used in front slot numbers 7 and 8.
Note The three types of BCCs with their proper backcards may be operated together temporarily
for maintenance purposes, e.g., replacing a failed controller card. Throughout a network, individual
BPX switches may have either a single BCC-32, BCC-3, or BCC-4 controller card or a pair of
BCC-32 cards, a pair of BCC-3 cards, or a pair of BCC-4 cards.
