CelXpres T8206
Asynchronous Transfer Mode (ATM) Interconnect
Product Brief
April 2000
Description
(continued)
Figure 2 illustrates the use of the CelXpresT8206 in a system with dual backplane cell buses using shared UTO-
PIA mode. In this configuration, both T8206 devices on each card receive cells from the UTOPIA bus, and each
device uses its translation table to determine if the cell should be transmitted on its backplane cell bus. In the
egress direction, each T8206 device receives cells from its cell bus to transmit on the UTOPIA bus. Queue priori-
ties are resolved using a two-wire interface between the two devices. Although a single ATM virtual connection
cannot use both backplane cell buses simultaneously, no restrictions exist for a single PHY utilizing both back-
plane cell buses for different virtual connections. In the event of a bus failure, the T8206 devices may be config-
ured for one device to assume bus responsibility from the other.
