MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS.

OFF-ISOLATION IS MEASURED BETWEEN COM_ AND “OFF” NO_ OR NC_ TERMINAL ON EACH SWITCH.

ON-LOSS IS MEASURED BETWEEN COM_ AND “ON” NO_ OR NC_ TERMINAL ON EACH SWITCH.

CROSSTALK IS MEASURED FROM ONE CHANNEL TO ALL OTHER CHANNELS.

SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
