Functional Description

The BPX switch is a space switch. It employs a crosspoint switch for individual data lines to and from
each port. The switching fabric in each BPX switch consists of three elements for the BCCs (see
Figure 3-2):

Release 9.3.0, Part Number 78-10674-01 Rev. D0, July 2001
Runs the system software for controlling, configuring, diagnosing, and monitoring the BPX switch.
Contains the crosspoint switch matrix operating at 800 Mbps per serial link or up to 1600 Mbps
(BCC-4V).
Contains the arbiter which controls the polling each high-speed data port and grants the access to
the switch matrix for each port with data to transfer.
Generates Stratum 3 system clocking and can synchronize it to either a selected trunk or an external
clock input.
Communicates configuration and control information to all other cards in the same node over the
backplane communication bus.
Communicates with all other nodes in the network.
Provides a communications processor for an Ethernet LAN port plus two low-speed data ports. The
BCC15-BC provides the physical interface for the BCC-32.
The BCC-3-BC provides the physical interface for the BCC-3-32M, BCC-3-64M, and BCC-4V.
68EC040 processor operating at 33 MHz.
32 Mb or 64 MB option for BCC-4.
4 Mb of Flash EEPROM for downloading system software.
512 Kbytes of BRAM for storing configuration data.
EPROM for firmware routines.
68302 Utility processor.
SAR engine processor operating at 33 MHz.
Communication bus interface.
HDLC processor for the LAN connection interface.
Two RS-232 serial port interfaces.
Central Arbiter on each BCC.
Crosspoint Switch.
16 X 32 Crosspoint Switching Matrix on each BCC (2 X [12 X 12]) used for BCC-4V.
–
Serial Interface and LAN Interface Modules on each BCC and on each Function Module.
