1.2 Applications Overview
The CX28250 can be used in a number of applications:
Reassembly (SAR) device, such as the CX28236 SAR, to provide framing along
with segmentation and reassembly of ATM traffic. It can be used in
switch-to-switch links and switch-to-terminal links. The CX28250 connects to the
SAR via the UTOPIA and microprocessor interfaces (see
either loop-timed or source-timed. The device can be configured and controlled
through a generic microprocessor interface. For more information on applications
for the CX28250, see
• ATM LANs over optical fibers
• Workstations and PC Network Interface Cards (NICs)
• LAN switches and hubs
• SONET or SDH compliant ATM UNIs
The device is typically used in combination with a Segmentation and
