Service Provider’s RG
Telco Residential Gateway – telco operatorMigration from Dial-up to DSL increase the need for a DSL residential
gatewayVoice and data-centric broadband deviceNot wait for explicit residential gateway pre-existing home networking and
proprietary end-to-end service delivery Potential services
- Data» High-speed Internet data access
- Video» The viability of video services over DSL has yet to be determined» Streaming video of medium bit-rate(300-600kbps)
- Voice» POTS is very important RG to emulate a Private Branch Exchange(PBX)
Wireless home networking support will be forthcoming in a next step RG
Krnet 20015/42
Cable Residential Gateway – cable operatorHybrid fiber/coax(HFC) architecture provides for a bigger “pipe” than the
telcoDigital Set-top-boxes Potential Services
- Data» Traditionally not installed internally in PC, SP have rolled out external CM
- Video» Video will play some long-term role in cable residential gateways» Transmitted possibly using IEEE1394» Some jitter or latency if there are competing data or telephony services being carried
simultaneously» At least 4Mbps for MPEG-2 video streams
- Voice» Considerable investment in rolling out voice services over HFC» Opportunity to provide IP telephony using the Internet
No standard framework or architecture Not co-located with a phone jack it requires wireless home networking support
Krnet 20016/42
Utility-centric RG – utility operator Focused on energy metering as its core application Potential Services
- Automated meter reading» RG designed to support low data rates so that premises costs are lower
- Real-time energy management» To regulate the consumer’s own energy-consumption patterns
- Security monitoring- Remote management- Other services: health-care monitoring & traditional home
automationWhile most operators will benefit from the deployment of utility-centric
gateway, that is not necessarily the case with consumers

RG Group – GTE, Reltec, Telcordia, and so on (more than 25)Developing the Home gateway concept
Recommendation for RG
- Physical and protocol interfaces
- Software functions
- Hardware design principles
Krnet 200124/42
TIA/EIA TSB-110
TIA TR-41.5(Residential Gateway Task Group) To develop a set of standards on the distribution of multimedia service To interface TIA’s other subcommittees, VESA Home Network and DAVIC To provide system architecture at the gateway interface level
- Supported physical and protocol interfaces- Software functions- Hardware design principles
GTE, Lucent, IBM, Reltec, Telecordia(Bellcore) Scope
Residential GW system for single-tenant residences To develop a residential gateway standard that specifies a system that may be
made up of a single element or multiple elements that act in concert as a single system
Conformance with - FCC rules and regulations- National Electrical Code- National Electrical Safety Code
Krnet 200125/42
Overview of RG environmentRG : a system that provides an intelligent interface and mediation
facility between the service access lines and the consumer’s in-home networks and devices
Krnet 200126/42
System overview The RG should(mandatory) support the following classes of applications
- Communication services : voice telephony(wired/wireless), video telephony/ conferencing, distance learning, remote access to corporate networks
- Entertainment services : broadcast, satellite and cable TV
- Information services : online or Internet services
- Utility management : demand-side energy management and AMR
- Home automation services : premises security, lighting, appliances control
» POTS service· POTS service survivability in the event of commercial power outage, i.e., fail-false modes for the
analog POTS Components
- AGMs(Access Gateway Modules) : to terminate and mediate the associated external services(functions of the network interface units as described in TIA/EIA TSB-109, Multimedia Reference Architecture)
- PNMs(Premises Network Modules) : to terminate the in-home networks technologies and services (functions of the customer premises interface units as described in TIA/EIA TSB-109, Multimedia Reference Architecture)
- SMs(Service Modules) : additional plug-in modules to provide specialized services or to supplement the features and capabilities of the RG
Krnet 200127/42
Typical Residential Gateway Application
Krnet 200128/42
Operating System shall enable the RG to
Manage and allocate internal digital interface(IDI) resources
Unify the operation of multiple element gateways into a single system
Broker protocols
Integrate control over appliances, servers, clients, actuators, etc.
Provide directory/naming services used for addressing communications
to endpoints
Provide security functions and non-repudiating log files
Provide easy-to use interface for consumers

VESA Home Network VESA Home Network
Flexible and open network architecture specification for the home- allows the transfer of information among all connected, digital devices - allows interoperability between different networks in the home- provides a common interface to Residential Gateways which connect devices
in the home to access networks- provides home network management for devices and applications
Classes of Applications- Entertainment services -- distribution of video, audio, and in the home,
video games, and control of A/V devices such as TVs, VCRs, and set-top boxes
- Communication services -- voice telephony (wired and wireless), video telephony, video conferencing, distance learning, and remote access to corporate networks
- Information services -- Internet access, PC file and print sharing, news and information on demand, home shopping, and home banking
- Home automation services -- energy management, premises security, lighting and appliance control

Functionality of B-NT Functionality
Where the ports are of the same type, the same service set can be made available to either port NT and TE can be separated by at least 50m The interfaces are configured as network or hub ports The interfaces can be connected directly to the TE, or to an additional intermediate device local power a network referenced timing source(8kHz) over the ATM25/51 interface Sufficient buffering, queuing and intelligent discard Some unique device identifier
Not functionality Not terminate ATM signalling Not support CAC, shaping or policing for the Access link Not any customer specific information Not perform any customer or device authentication Not provide any encryption or security Not provide any means for the direct support of conditional access Not be service aware as such, except by means of its VC awareness. Not have its own IP address (it cannot be ‘pinged’ from the TE) Not ILMI functionality

Gateway Evolution
First generation gateways
Broadband (cable/ DSL) modems with built-in home networking for Internet sharing
Locally powered multi-line Multimedia Terminal Adapters
Will soon evolve into full-fledged home gateways
Network-powered integrated voice/data gateways
Intelligent device and service management
Modular architectures
With multiple form factors
Outside the house
Stand-alone inside the house
Integrated into the set-top box
Krnet 200142/42
Concluding Remarks
An extremely complex situation No dominant technology Many collaborations such as OSGi, HAVI exist
Technology-push rather than consumer-pull Fact or Fiction
Interest in home networks increasing from Telco, IT, Service & Utility sectors
The range and capabilities of connected devices will expand rapidly
The next wave will be the Home Network Home Gateway will be the Heart of the Home Network
