The ASI chassis may include one or two ASI boards (1 board = 4
4 outputs).
ASI outputs 1, 3, 5 and 7 are smart-secured: a bypass allows having a
signal even when the equipment is off.

Hybrid configuration (i.e. one ASI board + one Gigabit Ethernet

SMPTE 310M Mode
On an ATSC single switch with an ASI board, the interfaces can be
configured either in ASI or SMPTE 310M mode (19 Mbps only). This
configuration is a setup parameter, and the device reboots when this
parameter is modified. The numbering is the same in ASI and
SMPTE 310M.
