The FAB3 boards provide a full-duplex 320 Gbps switch fabric with multicast functionality to enable traffic switching between application boards. Node controllers enable service provisioning, monitoring, and alarm processing, and include a serial craft interface and Ethernet management port. Each FAB3 board has a separate data path to each application board for redundant traffic and management links.
KEY ATTRIBUTES
REDUNDANCY:
Two FAB3 boards are required in slots X and Y for redundancy. The FAB3 board in slot X is the master BLM 1500 system node controller and switch fabric. The FAB3 board in slot Y provides lossless failover protection if the master FAB3 board fails or is removed from the chassis.
SWITCH FABRIC:
The switch fabric is responsible for switching traffic between application boards through a highspeed backplane with an aggregate fullduplex capacity of 320Gbps. The FAB3 board provides a switch fabric with active/active redundancy with both fabrics carrying traffic simultaneously. The board has a non-blocking, single-stage, point-to-point serial architecture.
NODE CONTROLLER:
The node controller is responsible for all operation, administration and maintenance of the BLM 1500 and run in an active/hot-standby protection mode for immediate availability should failover occur.
EASY MANAGEMENT:
The FAB3 board supports provisioning and software management through the GUIbased EntriView™ EMS, CLI, TL1, and SNMP. Two external ports are provided on the faceplate: an RS-232 serial console and a 10/100BaseT Ethernet port for connection to a TCP/IP network.
SUPPORT FOR ALARMS AND DEVICE CONTROL:
The FAB3 board supports six alarm relay outputs for connection to external audible/visual alarm indicators at the central office. Alternatively, the board can be connected to 16 environmental sense point inputs and six control output pairs for external devices (such as sump pumps and other devices) to assist with monitoring and managing remote sites.
