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.
