Because line cards are highly susceptible to transient voltages, network hazards such
as lightning and power cross conditions pose a serious threat to equipment deployed
at the central office and in remote switching locations. To minimize this threat,
adequate levels of protection must be designed to ensure reliable operation and
regulatory compliance.
Protection Requirements
When designing over voltage protection for analog line cards, it is often necessary to
provide both on-hook (relay) and off-hook (SLIC) protection. Figure 3-18 shows this
being accomplished in two stages.
