Triple Play

Introduction to Triple Play & benefits

Triple PlayThe entire communications industry is undergoing significant and rapid change. Gone are the days of getting communications services from multiple service providers. In a move to leverage their broadband investments and expand relationships with subscribers using new services, cable, telco and utility companies have created converged networks to offer subscribers one stop shopping for bundles of voice, video and data services, known as the triple play.

With converged networks established and each service having its own in-home device (TV, PC and telephone line), a lucrative next step is interconnecting those devices to offer new and exciting services to subscribers that blend voice, video and data. And the proliferation of high-definition TV sets, HDTV, video on demand and digital video recorders have made TVs the focal.

point of consumers’ digital home life. Given the multi-device home networks in many households, there is a large business opportunity with TVs as the perfect centerpiece for converged services.

Initially some satellite and telco service providers deployed proprietary, in-home equipment to offer a converged service, typically caller ID and voicemail message waiting indication from one phone line to one TV. Because of the costs associated with deploying and upgrading that hardware and subscribers wanting similar information delivered to multiple devices, this was not a long-term option.

Service providers want a proven end-to-end triple play converged services solution that is standards-based to ensure compatibility with their existing network and the flexibility to support next generation equipment as the network evolves. The issue has been finding a viable architecture that can handle the coordination and delivery of real-time signals within and across the voice, video, and data networks. The solution also needs to deliver these converged services to a variety of digital home devices and cost effectively scale with demand to support up to millions of subscribers.

Triple PlayConvergence is a process that the service provider will endeavor by building both the network infrastructure & the applications layer in an open and service-oriented architecture to facilitate current expected & future anticipated set of services for both the residential (commercial) & enterprise markets.

What Salec is demonstrating is a first step towards a real convergence between data, voice & video networks with a scenario and setup that represents how the end user in his home will benefit from. A complete living room was built with all common items that are found in every home; a TV set, telephone line, & a computer.

The telephone line carries both the voice service and the DSL data service at the same time. The computer is connected to the Ethernet port of the DSL modem that is terminating the copper line, and a splitted port on the DSL modem provides the telephone line service to a normal telephone set. A digital IP Set-Top Box (STB) is connected to the Ethernet port of the DSL modem and provides the TV service to a TV set through the RCA audio video cables (like normal way a satellite receiver is connected to the TV set).

This what a normal user will see in his home; nothing changed except that the satellite receiver is replaced with the IP STB and no more coax cable is needed and no more dish mounting is required to get the TV services we used to.

Now what will a subscriber will get in Salec Triple Play Living Room? He will be using the computer for internet related services (browsing, email, chat, etc), will be using the telephone to make calls and receive them, and will be watching normal satellite channels.

The former mentioned user experience is the same we get in our home, but the converged solution adds more actually to just meeting the current services. The user can watch Pay-Per-View channels; all he needs is to enter PIN code and switches to the PPV channel at the specific schedule. No more phone calls are made to the operator as the IP STB provides the interactivity between the subscriber and the service provider billing.

It is worth mentioning here that the subscriber is interacting with IP STB using a remote control and in similar way he used to change and select channels in satellite receivers. The only difference is that the IP STB remote control has more buttons for extra service listing and interaction. For example, by clicking a specific button you get a list of the VOD titles available on the service provider network with their rating and rental cost.

By pushing downwards or upwards arrows, subscriber can navigate through the whole list and select the required movie and agrees to pay the listed charge by entering his PIN.

One of the most important parts of the show, was a Salec own developed solution for giving the subscriber the control of his phone line from the computer. Through client software installed on the subscriber computer, the subscriber will register his phone number/line to his DSL internet connection through a customized web site. If done, then the client software will be communicating with a developed voice portal.

Once a call comes onto the subscriber line, the voice portal will push a message to the client software that will display the Caller ID with alarm sound. On the client software, there is a button to discard or divert the call to a voice mail. This finds a real life application when the subscriber is using his computer and a call comes in, he won’t need to move from the PC to the phone, he can just know the callers and decide what to do; discard, divert to voice call, or just move and pick up the line. Also, the subscriber can install the client software on his work computer and monitor his home line while he is away from the home.

Salec has partnered with Zhone Technologies in building a sample service provider network in the booth as shown below

In the above drawing, the CO building represents a sample of telecom central office building and the living room represents the subscriber home with the copper line in between. In the following, a highlight of each CO component is given:

Zhone MALC is a fully-featured Packet Loop Carrier (PLC) optimized for delivering voice, data, and video services over a pure packet access network. MALC gives carriers the flexibility to cost-effectively deliver triple play services over existing facilities today and to migrate these services on a port-by-port, service-by-service basis to a pure packet network. In this setup, the MALC was equipped with one Combo card that delivered both ADSL2+ DSL service and packetized voice service on the same port.

The uplink is a Gigabit Ethernet port that routs and forwards the internet traffic and multicast traffic of the live TV channels. The combo card receives the packetized voice packets destined to specific port and convert them back to analogue signal and send them over the copper pair. The MALC control card is responsible about voice signaling and communication with the Call Handling server to exchange control & supervision signals to facilitate voice communication.

The TVoIP Cluster represents a sample TV Head end, it contains a dish with professional satellite receiver to decode a complete transponder channels, then the professional receiver is directly connected to LiveTV streamer which takes the channels MPEG2 stream, encapsulate them in IP packets and send them as multicast IP stream over the Ethernet.

The Video On Demand VOD server hold many MPEG2 encoded movies in a classified manner and ready to serve them upon request. The Middleware server is the brain of the head end which ties everything, it communicates with the streamer appliance to learn about received channels and their performance, classify them in the service provider defined packages.

When the subscriber IP STB first boots up, it starts looking for the middleware on a predefined procedure and when found, it download the needed boot files, Live TV packages as purchased by the subscriber and also the interface for the subscriber. When the user selects a movie, the middleware will ask the user to enter his PIN number and compares it against the stored value. If a match is found then, the middleware will instruct the VOD server to send specific movie to the requesting subscriber.

The VoIP Cluster is a sample of next generation voice network that could be deployed in service provider network to offer converged services. The Call Handling server is the one responsible for packetized voice switching (based on softswitch).

It is based on SIP and communicates with MALC for registered voice ports. When a call comes in form the PSTN through the voice gateway, the voice gateways notifies the call handling server about the caller ID & also the called number.

The call handling server then switches the calls to the MALC and at the same time send the call to the Call Appearance server. The call appearance server is the one responsible for communication with the client software installed on the subscriber desktop/laptop. When the call appearance receives the notification from the call handling server, it automatically sends/pushes the call information (caller ID) to the client software, in return the client software will display to the subscriber a message that someone is calling with this caller ID while the phone is ringing.

The client software has buttons for the subscriber to use. One of these buttons, for example, can discard the call and the other can switch the caller to voice mail. If the discard button is selected, the client software will send a notification message to the call appearance sever which will forward the request to the call handling server that will send busy signal to the voice GW and clears the call from the MALC. The Customer Management server is responsible for correlating subscriber land line numbers with their desktop/DSL connection parameter and used when the subscriber connects for the first time.
