IP Telephony news wrap-up for Feb 9 – 2006

The ITU has approved a suite of CableLabs’ PacketCable specs as standards for the international version of services including VoIP. PacketCable-based standards are known internationally as IPCablecom, and this recently approved suite covers such topics as architecture, network call signaling, call management server (CMS) to CMS signaling, QoS, support for multimedia and other functions necessary to provide time-critical interactive services over a cable television network using IP.

The ITU approval stems from work carried out in October by ITU SG 9, which is entitled Integrated Broadband Cable Networks and Television and Sound Transmission group. SG 9 is chaired by CableLabs President and CEO Dr. Richard R. Green. ITU approval came in late November after consultation with its member states and sector members.

The ITU also standardized on CableLabs’ contributions from DOCSIS and CableHome projects. J.128 is a set-top gateway specification for transmission systems for interactive cable television services. J.197 pertains to high-level requirements for a digital rights management bridge to a home network and a revision to J.192, a residential gateway to support the delivery of cable data services, which aligns it with CableHomeÆ 1.1.

A new Recommendation J.601, for Transport of Large Scale Digital Imagery (LSDI) applications, defines transport technologies for LSDI with resolutions 3840 x 2160 pixels and 7680 x 4320 pixels.

Recommendation J.280, Digital Program Insertion, or splicing application programming interface, was amended to add functionality that creates a new logical multiplex type that allows for multiple ports to be utilized. Previously when utilizing certain types of content servers over Gigabit Ethernet, it was not always practical to create a multi- program transport stream that would work using the original standard.

At the next SG 9 meeting, scheduled for May, the group will consider more CableLabs generated specifications for standardization including J.dti, DOCSIS Timing Interface Specification; J.bb, Battery Backup for Cable-based Devices; and J.161, audio and video codec requirements for provision of bidirectional services over cable television networks using cable modems.

Ranch Networks has introduced a line of appliances (RN300, RN20, RN40, and RN41) to provide dynamic, protocol independent, per call authenticated network access for Asterisk-based systems.

The technology sends instructions to the firewall to open the ports on an as needed basis. Media streams can flow from one phone to another, then close ports when the call is terminated. Instructions are also sent to the appliance determining the amount of bandwidth needed. As calls come in, data is shrunk to allow necessary bandwidth on a protocol basis. The appliances support multiple phones behind any number of firewalls.

The RN products range in price from $750 to $20,000.
