Hello
wikipedia describes line cards as typically used in telephone exchange systems to terminate connections. With regard to this I have two questions:
1) are there line cards used in Ethernet equipment? As for my knowledge, a lot of Layer 2 switches have hot-swap modules on-board, supporting fiber connections ec. Are they classified as line cards as well ? 2) what does "terminate connections" mean? Does it mean that a data stream doesn't pass beyond the line card, or it implies something different?Thanks.
