APPLICATIONS
• Mini-DSL Access Multiplexers (Mini-DSLAMs).
• Subscriber Access terminal devices.
• APON Customer Located Subscriber Access Equipment
• LMDS Customer Located Subscriber Access Equipment.
• Integrated Access Devices.
Figure 1 shows the S/UNI-APEX-1K800 in a mini-DSLAM application. The
S/UNI-APEX-1K800 acts as a cell buffer and traffic manager. The S/UNI-ATLAS-
1K800 provides address resolution and policing.
The mini-DSLAM application supports eight LIU devices per Line Card. Each
xDSL modem is connected by its Utopia port to a FPGA which provides an
interface to the AnyPhy bus. If Hot Swap capability is needed the bus signals
need to be passed through switching or tristate drivers to isolate the card when
being plugged in.
The FPGA performs the task of interfacing several 31 logical port Utopia bus
signals to the single 128 logical port Any-PHY bus supported by the S/UNI-
APEX-1K800.
