Cisco MGX 8230 Edge Concentrator Installation and Configuration
Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
Chapter 1 Introducing the MGX 8230
MGX 8230 System Overview
The Applications of the MGX 8230
The MGX 8230 operates in the following applications:
Note Refer to the Cisco document MGX 8230 Edge Concentrator Overview for additional information on
the applications of the MGX 8230.
Note See Chapter 5, “Configuring the MGX 8230 Shelf” for information on configuring MGX8230
applications.
As a feeder
The MGX 8230 concentrates narrow-band and medium-band ATM, Frame Relay, and into a single,
wide-band ATM feeder trunk that connects to a BPX 8600-series switch or a MGX 8850 switch.
As a Stand-Alone Switch
The MGX 8230 can be deployed as a stand-alone switch, providing “cross-connect” connections
between UNI and NNI ports. Traditionally, this would be used in a concentration-type mode, allowing
standards-based adaptation and concentration of multiservice traffic onto one or more high-speed ATM
interfaces. This enables the MGX 8230 to interface to a multivendor ATM network, or to any other ATM
attached device (such as a Cisco 7200 or GSR router LS1010, MSR 8450, and so on).
The MGX 8230 interfaces to the ATM equipment using a standard ATM UNI or NNI..
Multiprotocol Label Switching (MPLS)
As a component of the BPX 8680-IP universal service node, the MGX 8230 is capable of forwarding
traffic into the BPX MPLS network by acting as a multiservice feeder
Consolidation of Cisco CPE Traffic
At the edge of the network, the MGX 8230 can interwork with and consolidate a wide variety of CPE
equipment.
Multiservice Stand-alone Concentrator
The MGX 8230 can be deployed as a stand-alone concentrator, interfacing to a multivendor ATM
(non-BPX) network, as shown Figure 1-5. The MGX 8230 interfaces to ATM equipment using a standard
ATM UNI or NNI.
Universal Edge Architecture
The MGX 8230 supports a wide range of services over narrowband and mid-band user interfaces by
mapping all service traffic to and from ATM using standardized interworking methods. The MGX 8230
supports up to 64 channelized or non-channelized T1 and E1 interfaces on a single IP + ATM
multiservice gateway
