Applications
The MGX 8830 or MGX 8830/B switch operates:
• As a stand-alone switch—The MGX 8830 or MGX 8830/B switch can be deployed as a stand-alone
switch, providing cross-connect connections between UNI and Network-to-Network Interface
(NNI) ports. The switch acts as a concentrator, allowing standards-based adaptation and
concentration of multiservice traffic onto one or more high-speed ATM interfaces. This enables the
switch to interface to a multivendor ATM network, or to any other ATM-attached device. The
Cisco MGX 8830 switch interfaces to the ATM equipment using a standard ATM UNI or NNI.
• As a consolidator of Cisco customer premises equipment (CPE) traffic—At the edge of the network,
the MGX 8830 or MGX 8830/B switch can interwork with and consolidate traffic from a wide
variety of CPE equipment.
• As a multiservice stand-alone concentrator—The MGX 8830 or MGX 8830/B switch can be
deployed as a stand-alone concentrator, interfacing to a multivendor ATM (non-BPX) network. The
Cisco MGX 8830 switch interfaces to ATM equipment using a standard ATM UNI or NNI.
Interface Support
The MGX 8830 or MGX 8830/B switch supports a wide range of services over narrow band and
mid-band user interfaces. It uses standardized interworking methods to map all service traffic to and
from ATM. The Cisco MGX 8830 switch supports up to 64 channelized or non-channelized T1 and E1
interfaces on a single IP + ATM multiservice gateway.
The MGX 8830 or MGX 8830/B supports the following user traffic interfaces:
• Frame Relay UNI on HSSI, T1, and E1 lines
• ATM UNI and Frame user network interface (FUNI)
• Optional inverse multiplexing over ATM (IMA)
• Frame Relay to ATM network interworking and service interworking
• Circuit emulation services for T1 and E1 lines
The modular, software-based system architecture enables the MGX 8830 or MGX 8830/B switch to
support new features through downloadable software upgrades or new hardware modules.
