Chapter1 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 docume nt MGX 8230 Edge Concentrator Overvie w 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 MGX8230 concentrates narrow-band and medium-band ATM, Frame Relay, and into a single,
wide-band ATM feeder trunk that connects t o a B P X 86 0 0-se ries switch or a MGX 8850 switch .
As a Stand-Alone Switch
The MGX 8230 can be deployed as a stand-a l on e s wi tc h, providing “cross-connect” co nnect ions
between UNI and NNI ports. Traditionally, this would be used in a concentration-type mode, allowing
standards-based adap tat ion and concentration of m ul ti service traffic onto one or more hi gh-speed ATM
interfaces. This enab les th e MG X 823 0 to in te rf a ce to a m ul ti v e ndo r ATM network, or to an y oth er 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 netw or k by ac ting as a multiservice feede r
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 depl oy ed as a stand-alone concentr ato r, in ter fa cin g to a multivendor ATM
(non-BPX) network, as shown Fig ure 1-5. The MGX 8230 interf aces to ATM equipment using a stan dard
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
