Triplett made a "Control Line Test Set" for Motorola, with the Moto model number R1034A . Some were labeled R-1034A (i.e. with a hyphen). They show up on ebay every so often for $10-50. If you are responsible for an AC wireline it's unbeatable at that price. I picked up one at a hamfest for $20 a

Anyone know the answer to the original question. How do you make sure you have enough high level, function, and low level guard tones at the repeater input? The way I see it you have the keyer output into the phone line to make your initial adjustment. Then the repeater has a line input as well.
