1.5.5 MiniBNC EIA
• DS3/EC1-48
MiniBNCs support available high-density cards in unprotected and 1:N protection (where N < 2)
protection groups.
Table 1-3 shows protection groups and their applicable slot assignments.
1.5.5.1 MiniBNC Connectors
You can install MiniBNCs on one or both sides of the ONS 15454. As you face the rear of the ONS 15 454
shelf assembly, the right side is the A side (15454-EIA-BNC-A96) and the left side is the B side
(15454-EIA-BNC-A96). The diagrams adjacent to each row of connectors indicate the slots and por ts
that correspond with each connector in that row, depending on whether you are using a high density (HD)
or low density (LD) configuration. The MiniBNC connector pairs are marked Tx and Rx to indicate
transmit and receive cables for each port.
Figure 1-16 shows the ONS 15454 with preinstalled MiniBNC EIAs.
To install coaxial cable with MiniBNC connectors, refer to the “Install the Shelf and Backplane Cable”
chapter in the Cisco ONS 15454 Procedure Guide.
