The Cisco ONS 15454 Turn-up Electrical Continuity Test Card is a solution for confirming proper DS-1 and DS-3/EC-1 cabling between the Cisco ONS 15454 shelf assembly electrical interface adapter (EIA) panels and the user's patch panels. The solution is designed for shelf installations that are not carrying traffic or powered and tests for common wiring errors including electrical shorts, opens, wrong connections, and tip/ring reversals.
The turn-up test card is sold in kit form, and is composed of two main components; an electrical continuity test card and a hand held console (HHC) with appropriate test cables. The electrical continuity test card plugs into the Cisco ONS 15454 shelf assembly and inserts a signal on the electrical ports. The hand held console is used at the patch panel to receive the signals from the ECTC. The HHC provides the user the ability to save the test results to memory for future download to a computer for recordkeeping. The test card can also be set in loopback mode, enabling any standard DS-1/DS-3 test set to be used for signal testing.
