System Specifications 3-49

Common Core Group

• Wireless

Support is available for analog and digital cellular, wireless data, and enhanced specialized

mobile radio (ESMR) services from a single BPX 8600 switch.

Broadband and Narrowband Services

The BPX 8600 series switch has a modular design that supports the following broadband and

narrowband user services:

• Broadband shelf

• Virtual trunking

• Multicast

• Tag Switching

• Broadband Shelf

The broadband shelf provides a 20-Gbps crosspoint switching fabric in a 15-slot chassis. Three

slots are reserved for common control modules, and 12 slots are provided for interface modules.

The switch has a midplane design, and each front card has a corresponding line module providing

the physical interface to the transmission media. This design permits easy upgrading or replacing

of function modules without disturbing cabling.

The broadband shelf design includes four functional card groups: the common core group, the

broadband switch group, the service interface group, and the network interface group. A separate

network management interface provides the connection to the StrataView Plus network

management platform.

Common Core Group

Common core cards provide the following functions:

• ATM cell switching

• Internal and remote node communication

• Node synchronization

• Network management communication

• Shelf management communication

• Alarm and status monitoring

The broadband controller card is a microprocessor-based system that is used to control the overall

operation and provide circuit switching for the BPX 8600 switch. The broadband controller card is

a front card that is usually equipped as a standard pair, which is a system option. Slot 7 and Slot 8

are reserved fro the primary and secondary, or standby, broadband controller cards. Each broadband

controller card requires a corresponding redundant line module back card.

There are three broadband controller interface cards:

• BCC-4

The BCC-4 is a new 19.2-Gbps control card that enhances the potential of Stratm technology in

nodes equipped with BXM function modules. The BCC-4 provides enhanced processing power for

general administrative node functions and provides the BPX with a 16 x 32 switching matrix. The

BCC-4 supports 4 MB of BRAM and 128 MB of DRAM.
