Token-Ring Telemetry Interface Status LED

The optional Token-Ring telemetry interface has an LED for Activity. This green

LED is turned on when data is being received from the network or transmitted by

the probe. When flashing, the frequency shows the amount of traffic. During

periods of steady traffic, the LED may appear to stay on solid.
