ETHERNET MANAGEMENT MODULE OVERVIEW
The Cabletron Systems Ethernet Management Module with Ethernet
(EMME) is the heart of the Cabletron Systems Multi Media Access
Center. The EMME can provide four bridged and managed channels and
management for three separate Ethernet channels within a single MMAC.
This is accomplished by having channel A operate over the Power and
Management Bus, Cabletron’s original Ethernet channel. Channels B and
C operate over the Flexible Network Bus (FNB). The EMME can also
bridge all three channels to a fourth externally connected channel (D,
usually a backbone connection), using one of the AUI ports on the
faceplate of the module.
The Cabletron Systems Ethernet non-repeater Media Interface Modules
use channel A on the MMAC backplane to communicate with the EMME
which performs the repeating function. MIMs provide a variety of
different media connections at one point within an MMAC. The EMME
incorporates an IEEE 802.3 repeater to provide repeater functionality for
these MIMs.
The EMME is fully compliant with IEEE 802.3 standards and provides
support for Spanning Tree IEEE 802.1d and DECnet.
