Overview

The SYNCHRONY Cell Exchange ATM products offer a flexible, modular,
scalable, and cost effective multi-access solution for WAN connectivity to
emerging ATM networks.

Multi-access functionality allows users to transition into new ATM technology at
their own pace, while preserving their investment in the existing application
infrastructure.

The SYNCHRONY Cell Exchange products provide the user with an ATM Cell
platform that serves on the "network edge" to multiplex and concentrate cell
bearing traffic (ATM), Frame Relay and legacy (IP, Ethernet, TDM, async, bi-
sync, SNA) traffic.

The SYNCHRONY Cell Exchange products enhance the capabilities of the
SYNCHRONY family of products, and their flexible architecture and interface
diversity make them ideal for a full range of ATM applications. The current ST
products connect to the ATM services through these Cell Exchange products.

Flexibility is the key when it comes to managing the Cell Exchange CX-1500 and
CX-1540. It offers both a user friendly, menu driven configuration and diagnostic
system and an industry standard SNMP V.2 management capability. Access to
these management systems can be accomplished locally via a direct connect RS-
232 port, 10Base-T port (RJ-45), or remotely either through the network or via
dial-in modem.

The CX-1500 is a compact, rack mountable, 15 slot chassis that can operate
with any combination of CPE
or network interfaces.
The state-of-the-art cell bus
backplane switches and multiplexes
data from a wide variety of interface
modules ranging in speed from
2.4 Kbps to 155 Mbps.
Interface modules supporting
both terrestrial and satellite communications networks makes "ATM Anywhere" a
reality. For high reliability applications that require a minimum of downtime, the
CX-1500 can be optioned with a redundant Power Supply and/or CPU.

The CX-1500 flexible architecture and interface diversity make it ideal for a wide
range of ATM applications. Combined with comprehensive SNMP, full traffic
management and its "Any to Any" connectivity, the CX-1500 provides powerful
ATM service capabilities with maximum network efficiency.
