There's a switch labeled "IRIG" which stands for Inter Range
Instrumentation Group, and refers to a standard for
telemetry encoding. There is a standard for time code, a
standard for modulating analog signas onto a bunch of FM
carriers, and a standard for multiplexing several analog
signals onto one FM carrier.
Apollo documents are probably VERY hard to come by these days.
