Abstract
In a switching network, a single 16 slot protective chassis supports a plurality of different adaptation switch modules (ASMs) sharing a single midplane bus. Multiple, identical ASMs form redundancy groups wherein one module in a group operates as a backup. Each ASM has relays for isolation between ASMs, and repeater circuitry to strengthen signals and minimize signal interference.
