Nope- This system is the system BEFORE the ZTD.. Cabinet was squarish- not long and tall like the ZTD. Programming was accomplished by watching LEDs on the attendant phone (Utility Series switch), or if you had the "Hi Feature" version, via the LCD screen on the attendant phone.

I still have 2 of these that I service, both customers are lawyers who are within a year of retiring and not needing or wanting an upgrade. Nice little systems.

Sometimes the thoughts in my head get so bored, they go for a stroll through my mouth. This is rarely a good thing.
