NOTES: MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT SOCKET TERMINALS.

OFF-ISOLATION IS MEASURED BETWEEN COM AND "OFF" NO TERMINAL ON EACH SWITCH.

ON-LOSS IS MEASURED BETWEEN COM AND "ON" NO TERMINAL ON EACH SWITCH.

CROSSTALK IS MEASURED BETWEEN ADJACENT CHANNELS WITH ONE CHANNEL ON AND THE OTHER OFF.

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