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 conso lidate 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 ran ge 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 CiscoMGX 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.
