Beta Draft ConfidentialOverviewHardware Module Descriptions


Base Input/Output ModulesThe ATM base input/output (BIO1 or BIO2) modules provide ATM layer processing for four independent 622 Mbps cell threads. Each BIO thread interfaces cells to or from a physical interface (phy) module and to or from the switching fabric port. A phy module may be a quad OC-3c/STM-1 or a single OC-12c/STM-4 module on a per-thread basis, or an OC-48/STM-16 module on a per-BIO basis.

The BIO2 module includes all features of the BIO1 module, and the following enhancements:

Increased call handling performance. Explicit forward congestion indication (EFCI) marking on the cell header, which,

when set, enables congestion control on a per-virtual circuit (VC) basis. Traffic management features.

Number of Supported Modules

There can be up to 10 B
