The DS11 Multiple Line Synchronous Interface is an early synchronous serial line interface for the UNIBUS; it can handle up to 16 lines.
It consists of a master line scanner, and up to four adapters, each of which can handle up to four lines. Physically, it is a large backplane, mounted in a 19" cabinet such as an H950, along with an DEC indicator panel; each line has a separate quad M7110 Line Control Module.
