WAN Configuration

 

throughput of up to 1.544 Mbps. Time Division

 

Multiplexing (TDM) allows for channelization of up to 24

 

links over a single physical T1/FT1 interface.

DELTD-UI

This port interface module provides both a T1 and DDS

 

interface that allows you to easily switch between the

 

two interfaces by changing the physical cabling and

 

reconfiguring the desired interface with either QuickSET

 

for the DELHW-UA or NetSight Element Manager.

For more information on these port modules, consult the appropriate hardware documentation or your QuickSET for the DELHW-UA documentation.

NOTE

The DELDI-UI and DELE1-UI are not supported by NetSight Element Manager at the time of this release. To configure these port interface modules, use the QuickSET for the DELHW-UA application that was shipped with your device. See your QuickSET documentation for more information.

See The WAN Logical View on page 7-4for details on accessing the WAN Logical View window through the DELHW-UA Chassis View.

WAN Redundancy

For a redundant wide-area connection, one of the WAN interfaces on your DELHW-UA can be configured as a primary link, with the other interface designated as the backup. If the primary link should fail for some reason, the other WAN interface will take over as the wide area link until the primary is restored.

When a DELST-UI is installed as the backup interface, that connection will activate and provide an ISDN connection to the wide area network, if the primary WAN link fails. The ISDN WPIM can also provide backup for single or multiple Data Link Connection Interfaces (DLCIs). If a leased line loses a DLCI or a remote office, for example, the DELST-UI will restore a 64K connection for that site while the rest of the connections remain on the leased line. For more information on WAN redundancy and the DELST-UI, consult your QuickSET documentation or your hardware documentation.

NOTE

The DELST-UI is designed for WAN ISDN redundancy only and is not intended to be used for a primary WAN connection at this time.
