Cisco Edge Concentrators
Used Cisco 8200 Series Edge Concentrators
The Cisco MGX 8230 Edge Concentrator provides a gateway for
narrowband services in space and power limited situations. The MGX 8230
acts as a standalone gateway or as a feeder for the Cisco IGX 8400 and
Cisco BPX 8600 Series Multiservice Switches. The MGX 8230 offers a full
range of narrowband service interfaces and a switching capacity up to
1.2 Gbps.
The MGX 8230 delivers Frame Relay, Circuit Emulation (CE), ATM cell
relay service, IP VPNs (VoIP, VoATM) and voice at high volume and with
high scalability—from DS0 to OC-12C/STM-4 speeds. The MGX 8230 chassis
accommodates narrowband interfaces from DS0 with port density scaling to
more than 1000 DS1s of service interfaces.
The MGX 8230 supports both Layer 2 and Layer 3 services including:
- IP VPNs using Cisco IOS software-based MPLS/label switching
- Voice-over-IP and voice-over-ATM
- Frame Relay services
- High-density Point-to-Point Protocol (PPP) for Internet access and
aggregation
- Narrowband ATM for managed data, voice, and video services
- Circuit Emulation (CE) for private line replacement
The MGX 8230 platform can also support a wide range of services over
narrowband and mid-band user interfaces, mapping all the service traffic
to and from ATM, based upon standardized interworking methods.
The MGX 8230 switches support up to 64 channelized or unchannelized T1
and E1 interfaces on a single switch, providing support for Frame Relay
UNI and NNI; ATM UNI, NNI, and FUNI, Frame Relay-to-ATM network
interworking; and Frame Relay-to-ATM service interworking. Using the
Service Resource Module (SRM), multiple T1 interfaces can be supported
on physical T3 lines. Frame-based services on T3 and E3 high-speed lines
are also supported. The MGX 8230 switches also support the use of
Inverse Multiplexing for ATM (IMA) to provide ATM trunking below T3/E3.
The MGX 8230 can be either rack mounted in a 19-inch rack, or fitted
with side panels to be a free-standing box. An optional mounting bracket
kit is available for mounting in 23-inch racks.
