The IDT77950 is an ATM Reference Design based on IDT's innova-
tive SwitchStar products, the IDT77V400 Switching Memory and the
IDT77V500 Switch Controller. The Switch is made up of two separate
board components: the 7M950 motherboard, which contains the
Switching Fabric function based on IDT's Switching Memory and Switch
Controller, and an individual IDT77955 OC-3 line card for each individual
transmit receive port.
The 1.2 Gbps ATM switch has eight receive and eight transmit ports.
The Switching Fabric, made up of the IDT77V400 and IDT77V500
SwitchStar products, resides on the motherboard. Each individual port
resides on a line card which is interfaced to the motherboard via a Line
Card PCI connector. Up to eight line cards can be connected to the
motherboard, with each line card running at 155 Mbps.
One of the line cards (Port 7) is used for communicating with a
remote PC to configure, read status and perform Signalling, PNNI and
OAM cell handling for the switch. All the necessary software functions
are performed by the remote PC.
