Xedge Hardware Overview
Xedge 6000 for ATM Applications
GDC supports selected discontinued Xedge adaptation controllers and cell controllers, described
below. These legacy controllers (under Version 6.2 switch code) are intended for ATM
applications.
•
Xedge adaptation controllers (CE, ETH, VSM) connect existing network technologies, e.g.,
Frame Relay and Ethernet, to the ATM switch.
•
Xedge cell controllers (ECC, ACP, ACS) perform dedicated ATM cell processing functions
such as traffic management and Virtual Channel Identifier/Virtual Path Identifier (VCI/VPI)
translation. Physical interfaces connect with other Xedge switches, and attach to LAN hubs,
routers, PBX equipment, high performance workstations and other devices with ATM
interfaces.
Note
The Xedge 6000 system no longer supports the following discontinued legacy Xedge modules: SCE, VE,
ISG(1), MPG2V, QEDOC, ATM NIC, VJLIM, VJH320, J2, DX21, DX27. To determine the support status of
legacy Xedge modules in your network, contact your GDC representative.

Provides up to 4 x DS1 or E1 ports with support for Channel Associated Signaling.
•
Supports Nx64K data (AAL1) and 64K PCM voice (AAL2) with CAS and idle channel
removal.
