No, the multi-button sets which work with Merlin are analog sets with a digital signaling system for sending button stimuli, and receiving lamp updates. The similar-looking multi-button sets sold with System 75 and 85 are digital sets that encode the voice as well as the signaling information into an ISDN-like bit-stream. The Merlin sets do, however, work with System 25 -- a true PBX with some key-system features. On this switch, the voice gets digitized by the port circuit in the switch, not in the telephone set. -- Dave Levenson Voice: (201) 647 0900 Westmark, Inc.
