We always did it the way Arthur said: All Telephone set T&R, whether Key or SLT, were cut down (with their A Leads of course)on the output of the card.
I have used 6Bs & Melcos for a variety of circumstances where a lead conversion was not possible (modems and fax machines especially). Never had a problem with them.
Matt, when you have all this A-Lead stuff mastered, there is another challenge for you -the ultimate uber-Alead application, that which struck fear into the hearts of telephone men everywhere for a generation (maybe two):
The dreaded REMOTE HOLD.
I can say no more. It's too frightening just to think of it.
