Repeater MAC Interconnection
Because all repeated data in the IMR+ chip or multi-
IMR+ chip design is available on the Expansion Port, all
network traffic can be monitored by an external Media
Access Controller (MAC) device such as the Am7990,
Am79C900, Am79C940, or Am79C960. A repeater with
such a controller is capable of providing extensive hub
management functions, as well as being addressable as
a network node. The MAC device can gather statistics
and data concerning the state of the hub and the
network, and the network addressability allows a remote
management station to monitor this statistical data and
to request actions to be performed by the repeater (i.e.
port enable/disable).
Figure 2 shows how to interface a repeater based on
multiple IMR+ devices to an Ethernet controller such as
the Am79C900 ILACC or the Am7990 LANCE. For more
information on this design, refer to AMD’s IEEE 802.3
Repeater Technical Manual, PID# 17314A.
