A line card or digital line card is a modular electronic circuit designed to fit on a separate printed circuit board (PCB) and interface with a telecommunications access network. A line card typically interfaces the twisted pair cable of a plain old telephone service (POTS) local loop to the public switched telephone network (PSTN). Telephone line cards perform multiple tasks, such as analog-to-digital and digital-to-analog conversion of voice, off-hook detection, ring supervision, line integrity tests, and other BORSCHT functions. In some telephone exchange designs, the line cards generate ringing current and decode DTMF signals. The line card in a subscriber loop carrier is called a subscriber line interface card (SLIC).

Data plane redundancy management with intelligent linecard
Devices, systems, methods, and processes for data plane redundancy management in network devices are described herein. A linecard in a network device may classify a plurality of packets into a first category or a second category based on whether a packet is a control packet or a data packet. The linecard may transmit all control packets and data packets to an active data plane. The linecard may selectively transmit the control packets and a sampled subset of the data packets to a standby data plane. Thus, the standby data plane is equipped with dynamic information of network using the control packets and Media Access Control addresses using the sampled subset of the data packets. When a failure is detected in the active data plane, the linecard starts transmitting all the data packets also to the standby data plane and starts accepting processed packets from the standby data plane for forwarding.
