is a project started by CableLabs
The purpose of the organization is to define standards for the Cable TV
CableLabs leads this initiative for interoperable interface specifications in order to deliver real-time multimedia services over two-way cable networks.
Built on top of the industry’s DOCSIS 1.1 (Data Over Cable Service Interface Specifications) cable modem infrastructure, PacketCable networks use Internet Protocol (IP) to enable a wide range of multimedia services, such as IP telephony, multimedia conferencing, interactive gaming, and general multimedia applications.
A DOCSIS 1.1 network with PacketCable extensions enables cable operators to deliver data and voice traffic efficiently using a single high-speed, quality-of-service (QoS)-enabled broadband (cable) architecture.
The PacketCable effort dates back to 1997 when cable operators identified the need for a real-time multimedia architecture to support the delivery of advanced multimedia services over the DOCSIS 1.1 architecture.
PacketCable interconnects 3 networks
PacketCable Voice Codecs per PacketCable Codec Specifications
- ITU G.728
- ITU G.729 Annex E
- PacketCable 1.0 comprises eleven specifications and six technical reports which define the call signaling, Quality of Service (QoS), Codec, client provisioning, billing event message collection, PSTN (Public Switched Telephone Network) interconnection, and security interfaces necessary to implement a single-zone PacketCable solution for residential Internet Protocol (IP) voice services.
- PacketCable 1.5 contains additional capabilities that do not exist in PacketCable 1.0, and superseded previous versions (1.1, 1.2, and 1.3).
- PacketCable 1.5 comprises 21 specifications and one technical report which together define the call signaling, Quality of Service (QoS), Codec, client provisioning, billing event message collection, PSTN (Public Switched Telephone Network) interconnection, and security interfaces necessary to implement a single-zone or multi-zone PacketCable solution for residential Internet Protocol (IP) voice services.
- Version 2.0 of introduces IMS Release 6 IP Multimedia Subsystem into the core of the architecture. Packet Cable uses a simplified IMS in some areas and enhances it in some cable-specific areas.PacketCable defined Delta specs related to the most important IMS specs from 3GPP.
VoIP services based on PacketCable architecture are being widely deployed by operators:
- PacketCable 1.5 Specifications Audio/Video Codecs - PKT-SP-CODEC1.5-I01-050128
- PacketCable 1.5 Specifications Network-Based Call Signaling Protocol - PKT-SP-NCS1.5-I01-050128 (see external link for MGCP information)
- PSTN Gateway Call Signaling Protocol Specification - PKT-SP-TGCP1.5-I01-050128 (see external link for MGCP information)
