Broadband Controller Card (BCCs)

Broadband Controller Card (BCCs)
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.
•
•
The three types of BCCs with their proper backcards may be operated together temporarily
Note
for maintenance purposes, for example, replacing a failed controller card. Throughout a
network, individual BPX switches may have either a single BCC-4V controller card or a
pair of the identical type of BCC.

Card. When a difference in operation does occur, the specific type of BCC is specified.
