Hoping to take a packet-based Internet-protocol standard to cable's world
stage, a group comprised of North American and European organizations announced
Wednesday that it has built a suite of specifications designed to deliver
advanced services over cable lines.
That specification, dubbed 'IPCablecom,' defines a core IP-cable architecture
for the delivery of voice and other evolving packet-based applications and
services. The spec has received backing from standard-setting organizations such
as the Society of Cable Telecommunications Engineers, the European
Telecommunications Standards Institute and the International Telecommunications
IPCablecom will serve a 'blueprint' to deliver IP, packet-based information
via cable-television networks, and it will give vendors the technological
details they require to build equipment that adheres to the spec, said Dr.
Richard Green, CEO of Cable Television Laboratories Inc., during a conference
call with reporters and analysts.
IPCablecom's roots are found in PacketCable, a CableLabs initiative aimed
primarily at the North American cable industry. Green said PacketCable has
essentially evolved into IPCablecom to fit the unique needs of cable operators
that serve particular regions.
The IPCablecom spec is comprised of 12 documents that define requirements for
signaling, quality of service, codecs, client provisioning, billing-event
message collection, public-switched-telephone-network interconnection and
IPCablecom also will address interfaces for specific 'zones,' which support
thousands to a few hundred thousand subscribers. Eventually, the spec will allow
operators to form national or international footprints.
'As the IP-based cable footprint expands globally, it is critical that we
have IPCablecom standards to connect to cable networks worldwide,' Comcast Corp.
senior vice president of strategic planning Mark Coblitz said in a press
