MGX 8230 System Overview

The Cisco MGX™ 8230 Edge Concentrator is a small footprint Multiservice Gateway specifically designed for Service Providers with space and power constraints. The Cisco MGX 8230 offers cost effective narrowband, voice, and IP services; and acts as a feeder shelf to Cisco BPX 8600 series, MGX 8850, and Cisco IGX 8400 series Multiservice Switches. The MGX supports the following services:

•IP VPNs using Cisco IOS software-based MPLS/label switching.

•The full suite of voice-over-IP, voice-over-ATM, and capabilities with full interworking.

•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.

Figure 1-1is an illustration of a MGX 8230 with its door attached. Note that there are light pipes in the door that display the status of the processor models (PXM1s).
