Welcome to the Cabletron Systems MMAC-Plus™ Remote Management for the 9A128-01™ User’s Guide. We have designed this document to serve as a simple reference guide for using MMAC-Plus Remote Management for the 9A128-01 FDDI/ATM bridge module. You should read through this guide to fully understand SPECTRUM Element Manager remote management for the 9A128-01.

The 9A128-01 ATM Access Module provides two bridging interfaces which allow you to connect an external ATM network to either one of the two FDDI networks resident on the MMAC-Plus hub’s FNB backplane. External front panel connections are made via a SONET, OC3 ATM interface. The 9A128-01 can be used to aggregate FNB trafﬁc to an ATM backbone, or provide connectivity between ATM workstations and traditional LAN users. The 9A128-01 is an 802.3 LAN Emulation Client (LEC) device and will operate in an 802.3 emulated LAN; see Chapter 6, LEC Administrator, in your SPECTRUM Element Manager Tools Guide for more information.

IETF RFC 1483 — Multi-Protocol Encapsulation over ATM Adaptation Layer 5 — speciﬁes a number of methods for encapsulating LAN trafﬁc for transmission over ATM networks. Current versions of the 9A128-01 ﬁrmware use 802.3 VC-based multiplexing for bridging protocols; the most recent version of ﬁrmware (2.10.13) supports ATM Forum LAN Emulation and UNI 3.0/3.1 SVC signaling; future version will add support for Cabletron’s SecureFast Switching.
