CableLabs is proposing a standards-based single-box customer premise solution that incorporates PacketCable, DOCSIS and VoIP.
CableLabs (Cable Television Laboratories, Inc), the nonprofit research and development consortium of the cable television industry, has issued an RFI (Request for Information) seeking an Integrated DOCSIS Access Device (IDAD) that will further integrate cable operators’ underlying technologies, allowing them to more effectively offer voice and data services to business and commercial customers.
For several years, cable television operators have been transitioning from their traditional delivery of entertainment programming to a position as full-service providers of video, voice, and data telecommunications services. DOCSIS cable modems and headend devices that enable the delivery of high speed data, digital television, and VoIP, are among the fundamental elements making this transition possible.
The RFI seeks a multifunction device for the customer premise end that integrates structured and unstructured T1 and related services as well as client interfaces ranging from traditional DS0-level FXS services to fully functional DS1 interfaces to 100 Base T. The DS1 emulation would be via IP, over DOCSIS. Some more sophisticated implementations would also take advantage of voice compression and dynamic bandwidth allocation between data applications and voice usage.
While IDADs are expected to be particularly attractive in VoIP networks, some operators may also desire the IDAD to function as a transport media for Primary Rate ISDN or DS1 trunks to a class 5 circuit switch, or for Frame Relay, cellular cackhaul, SS7 links, etc, CableLabs says. Finally, since this device also provides data services to a small business customer, some advanced data switching capability might be desirable.
RFI responses are due January 14, 2005.
