7.1 Creating a Redundant Circuit
A redundant circuit requires all the hardware necessary for two complete circuits, as well as the
following special devices, available from Canoga Perkins:
• Redundant ELIM cards.
• Y-Cable (Two connectors at one end, one at the other), for inserting into the remote and local
modem's electrical data link (The Remote ELIMs).
• Redundancy cable for the stand alone modem (if remote modem is rack version, no cable is
needed)
Figure 41 is an example of how to create two complete circuits in both the local and remote
locations. In this diagram, it is assumed the local modems are part of the Universal Chassis
System.
