DATA SHEET
The Cisco® ONS 15454 SONET electrical continuity test cards speed the verification of accurate electrical cabling during installation, troubleshooting, or new card additions.
PRODUCT OVERVIEW
The Cisco ONS 15454 electrical continuity test cards provide an efficient solution for system operators to verify that their DS-1, DS-3, and EC-1 electrical cabling between the Cisco ONS 15454 shelf assembly and the Digital Signal Cross-Connect (DSX) panel are correctly wired, detecting shorts, opens, wrong connections, and tip/ring reversals. The Cisco ONS 15454 test card is offered in two versions: a turn-up model designed for initial installations in a depopulated shelf assembly (Figure 1), and an in-service model designed for cabling additions for shelf assemblies currently carrying live traffic (Figure 2).
The turn-up test card operates in the protection card slots (slot 3 or 15) of a Cisco ONS 15454 shelf assembly and can test up to 112 transmit and 112 receive cables terminated on the side of the shelf in which the card is installed. The test card is powered by the shelf assembly or by an AC/DC adapter. The test card is compatible with Cisco ONS 15454 shelf assemblies installed with either lower- or higher-density electrical interface adapter panels and DS-1 or DS-3/EC-1 cabling.
The turn-up test card supports two operational modes: handheld or loopback. In handheld mode, the test card is used in conjunction with the Cisco ONS 15454 handheld console. Each cable (or cable pair) is verified by connecting the handheld console to each DSX port (Figure 3). The console's LCD panel and an audible sound will inform the user if the test signal is received correctly. In this mode, the console will store the test results that can be later downloaded and stored to a computer. The console can also be set to a manual mode of operation that is useful for debugging individual ports.

Turn-Up Test Card In-Service Test Card
In loopback mode, the test card is used in conjunction with a third-party vendor's test set. A test card in this mode will electrically connect (loop) the transmit and receive cables together for each circuit (Figure 4). A third-party test set can then be used to add a signal at the DSX panel and receive it back at the DSX panel, verifying the two cable paths for a circuit. Either mode of test operation can be performed by a single technician, eliminating the need for coordinated operations at the DSX panel and the Cisco ONS 15454 shelf assembly.
The in-service test card operates in any service card slot (slots 1-6 and 12-17) of a Cisco ONS 15454 shelf assembly and can test up to 56 transmit and 56 receive cables terminated on a shelf slot in which the card is installed. The in-service test card allows the user to select a specific cable group to test, allowing any remaining in-service cable groups to continue to carry traffic. The test card is only powered by the shelf assembly. The test card is compatible with Cisco ONS 15454 shelf assemblies installed with either lower- or higher-density electrical interface adapter (EIA) panels and DS-1 or DS-3/EC-1 cabling. The in-service test card supports the same handheld and loopback operation modes as well as test-result logging and downloading.

SUMMARY/CONCLUSION
The Cisco ONS 15454 test cards help the user to verify electrical interface cabling prior to the turn-up of live traffic. This can significantly reduce future costs and frustration from traffic turn-ups that may become delayed because of cabling errors. The test solution also provides a means for installation contractors to document that their work was performed satisfactorily.
