Newman University of Florida What is CEBus • Consumer Electronics Bus (See-bus) • Electronic Industries Association (EIA) Standard for – Physical interface for devices in the home to exchange information (TPBus, CXBus, PLBus, …) – Common language for them to “talk” (CAL) • Three aims: – Universal, low-cost, generic communication method for in-home devices – Reliable distribution of access services in the home – Reliable distribution of wide-band services within the home (e.g., DVR to TV, home theater, etc.) • Multiple media: TP, Coax (2 cables), PL, RF, IR CEBus History • Pre-1984 – X10, GE’s Homenet existing PLC methods • 1984 – EIA starts standards process IS60 • 1985 – field tests for PLC • 1986 – GE provides Homenet as a basis for CEBus (GE used X10 for their HomeMinder products), PLC 120 KHz 1Kbps ASK, CEBus named • 1989 – demos at winter CES, ASK PLBus ballot • 1991 – Intellon’s 10Kpbs spread spectrum PHY replaces ASK due to X10 incompatibility (“all lights on”) • 1992 - FCC part 15 rule amended for PLC, EIA releases Interim Standard (IS60) • 1994 – Standard revised • 1995 – IS 60 becomes ANSI/EIA standard EIA 600 CEBus Standards • Physical Layer/media IS-60.03/EIA-600.3x – 9 Parts: PL (1), TP (2), CX (3), IR (4) RF (5), FO (6), TP/CX/IR symbols (7), PL/RF symbols (8), ‘Node 0’ PHY NW support fcns (9) • Node Comm’s Protocol IS-60.04/EIA-600.4x – Part 1 Data Link, Part 2 MAC, Part 3 LL, Part 4 Network Layer Description, Part 5 Network Layer, Part 6 Application Layer • Router Comm Protocol IS-60.05/EIA-600.5x – 4 parts describing router function • Brouter Comm Protocol IS-60.06/EIA-600.6x – 4 parts describing brouter (wired/non-wired) function • Supplemental Data IS-60.07/EIA-600.7x – For future – not used • Common Application Language (CAL) IS60.08/EIA-600.8x – Part 1 CAL, Part 2 CAL Contexts (universal, data channel, tune, user interface) • Separate docs for context data structures – Lighting, audio/video, security, HVAC CEBus Design Constraints • Unskilled installer/user • Incremental installation • No preconceived network • Primarily residential network • Fast enough for existing residential tasks – 100 ms. max delay for light switch effect • Troubleshooting will be difficult • Security optional – Cable boxes, electric meters CEBus Physical Layer/media • PL (part 1) – 110/220 V. power lines – Use existing wiring, any AC powered device • TP (part 2) – four twisted pairs – Low DC voltage devices – thermostats, sensors – In place of or supplemental to phone wiring – CEBus distributes 18 V. to devices on TP0 • CX (part 3) – two coax cables – For ‘cabled’ devices like TV, VCR, DVR, etc....
