Twin core cable information transmission - uses line repeaters and terminal stations with buffering memories

摘要

An information transmission system over a twin core cable including a series of repeater units along its length. Each terminal station (A) (B) comprises a memory unit and an overlap input control for numerical data at a given bit debit rate (d). Information is read at a second bit rate (2d) and combined with control signals indicative of the amplification of the line repeaters (5). The receiver also includes a memory with input rate of (2d) bits per second and output rate of (d) bits per second.
