I learned that AT&T WorldNet is evaluating ASND's GX 550 to expand its all ATM backbone capacity to OC-12 and OC-48 using ASND's Navis network management SW. In addition to evaluating GX 550 for core switching, AT&T also evaluates the CBX 500 as an ATM edge switch as well.

The GX 550 Core ATM Switch provides the capacity of a core switch with the
intelligence of an edge switch, with first to market OC48/STM-16 trunking capability.

ATM core switching
OC3/STM-1 - OC12/STM-4
25-100 Gbps
Trunking up to OC48/STM-16

The CBX 500 Switch with multiservice capability allows service providers to deliver
ATM, Frame Relay and IP services on a single platform.

ATM, Frame Relay, and IP Switching
High Speed Frame Relay
2.5 - 5 Gbps switch capacity
10/100 Mbps Ethernet
DS1/E1 - OC12/STM-4

If ASND wins this contract potentially worth several hundreds of million dollars plus training, upgrade, and maintenence, there will be a significant upside suprise to FY98.

AT&T plans to extend the current OC-3 hub architecture and expand the network capacity to
OC-12 and OC-48. AT&T is currently deploying ATM switches to its backbone nodes. The
next phase is to convert the backbone network to an ATM switch fabric. AT&T plans to spend
$8 billion to $9 billion to upgrade its core infrastructure to SONET/ATM for all voice and data
services. As part of this effort, AT&T has already installed 30 OC-48 SONET rings across the
U.S., and plans to install an additional 50 in 1998.

Currently, dedicated AT&T WorldNet Managed Internet Service customer circuits are
back-hauled to one of the 11 backbone nodes for connection to the network. The next wave of
development for this infrastructure will be to deploy 100 concentrator nodes. The concentrator
nodes will be connected with the 11 backbone nodes through DS-3s. This second tier of
development will begin later in 1997 and continue into 1998. With the deployment of the
concentrator nodes, customer circuits will then be back-hauled to either the nearest
concentrator node or backbone node for connection to the network.
