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:

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.
