NEC D Term Series E DTP-16D-1 Digital Telephone @ LeMeridien Hotel San Francisco California

I visited San Francisco last weekend and this elegant hotel in the heart of the Embarcadero utilizes a NEC PBX with Dterm digital sets at main stations and analog sets in the hotel rooms.  These sets are the fourth generation digital sets.

NEC stands for Nippon Electronic Corporation, and their PBXs are probably the most durable and highest end of the PBX systems from Japan.
