INTRODUCTION
This section illustrates several types of applications in which the
MultiDSU64K is typically used. These types include:
• DDS point-to-point application,
• DDS multipoint (polled) application,
• Local Area Data Set,
• External Clocking application, and
• Analog Off-Net Extension application
DDS POINT-TO-POINT APPLICATION
In this application, the MultiDSU64K provides the interface between
the DDS line and the DTE at your site. Your network provider will
provide (at your request) a DDS line connecting the desired
locations. The figure below depicts a sample DDS Point-to-point
application.

DDS MULTIPOINT (POLLED) APPLICATION
Since your Central Office (CO) equipment must include "Multipoint
Junction Units" (MJUs) and other special arrangements for this type
of service, you may need to coordinate efforts with your network
service provider.
The MultiDSU64K at the host end is the Master Station (also called
the "Control Station"), which typically has RTS forced on. The
attached MultiDSU64Ks are called "Remote Stations" and have RTS
controlled by the DTE.
