The DL10 PDP-10/PDP-11 Interface Channel connects PDP-10 mainframes to PDP-11s used as communication front ends; up to 4 PDP-11's per DL10. It allows the PDP-10 to 'see' into the PDP-11's main memory, and vice versa (although the ability of the PDP-11 to do so is limited by the DL10's settings).

On the PDP-10 side, it connected to the PDP-10 memory bus, and also to two I/O busses (allowing it to be controlled by both processors in a multi-CPU system. So, it could be connected to KA10s and KI10s, but only to KL10s with the optional old-style busses.

On the PDP-11 side, PDP-11's connected to the DL10 have a special console which has a cable which goes to the DL10, which allows the PDP-10 to start and stop the PDP-11; the PDP-11's UNIBUS runs into the DL10 and is plugged into the DL10's backplane.
