Primary (A) and Secondary (B) H-Buses
The backplane’s primary and secondary H-buses (horizontal buses) link the MPC, NTC, and SLCs.
In this release, the primary bus carries all traffic. The buses operate at 160 Mbps total throughput.
Each H-bus has two parts:
• A downstream component broadcasts all cells received from the NTC interface to each SLC.
(Logic on the SLC filters and directs cells destined for each port.)
• An upstream component provides a contention mechanism for cells received from subscriber
ports to be funneled into the upstream NTC path.
Ethernet Management Bus
A 10Base2-type Ethernet bus in the backplane carries internal management traffic between the cards.
