HDM 2180 DS3 DSU Overview
This manual describes how to use the HDM 2180 DS3 DSU Craft
interface. As part of Verilink’s AS2000 modular platform, the HDM
2180 DS3 DSU provides a connection between T3 circuits and data
terminal equipment (DTE) and provides clear channel service for up
to 28 T1 or 44.7 Mbit/s.
Applications
Clear-channel DS3 networking is used primarily with high-speed
router backbones and mainframe channel extenders. The high-
speed capabilities of clear-channel DS3 networking provide the
bandwidth needed to meet the heavy demands of client-server
applications, such as CAD/CAM, video imaging, data warehousing,
data vaulting, and backup.
When the HDM 2180 is installed between large data centers it can
support mission-critical applications that mirror data between
mainframe computers or backbone routers. Installing a DS3 circuit
between data centers can ensure that information is copied to both
locations.
