    Module Slots and Rear Connections Rear Connections The rear of the NV8256-Plus (Figure 2-4 on page 10) features a backplate containing BNC connec- tions: 256 for receiving signals and 256 for distributing signals. These connections are passive and pass the signals through to active, receiving connections on the input cards and output cards.

  • Page 21: Router Control System Connections

    Serial Control Connections The NV8256-Plus has four serial ports, as shown in Figure 2-6 on page 11. The ports are divided into two sets, one primary (‘PRIMARY CONTROL’) and one secondary (‘SECONDARY CON- TROL’). Primary control is the connection to the primary control card. Secondary control is the connection to the secondary (optional for redundancy) control card.

  • Page 22: Diagnostic

    Some third-party router control systems require a GSC Node Bus connection. The GSC Node Bus connection is located on the rear of the router, as shown in Figure 2-8. The NV8256-Plus has one GSC Node Bus connection, labeled ‘NVISION AUX BUS’. The connection is shared by both the primary and secondary control card.
