Ahem, all's well that ends well.
Contacted a fellow phone dawg nearby and I'm
handing off to him. He serviced this actual system and has moved it once or twice.
With one program number, he helped me cure the stations not coming up, and with one more, not in the manual, but contained in release notes to dealers, I cured the "9,9" requirement for single line digital users. Better he spend an hour than I spend another full day fooling around and spinning my wheels and making mistakes. It's the better customer service as I see it.
Thanks to all you phone guys out there who care about our work.

Thanks for your help,

JE
