Background / Scenario

Convergence in the context of networking is a term used to describe the process of combining voice, video, and data communications over a common network infrastructure. Technology advances have made convergence readily available to large, medium, and small businesses, as well as for the home consumer. In this lab, you will research the converged services available to you.

Convergence – Converged networks are capable of delivering voice, video streams, text, and graphics between many different types of devices over the same communication channel and network structure. On a converged network, there are still many points of contact and many specialized devices, such as personal computers, phones, TVs, and tablet computers, but there is one common network infrastructure. An example of a converged network at home is a Triple Play service from Charter.com. Voice, Video (TV), and phone are bundled together and come into the home on one cable, typically hybrid fiber coax.

Part 2: Research ISPs Offering Converged Services

In Part 2, you will research and find two or three ISPs who offer converged services for the home, regardless of geographical location.

Step 1: Research various ISPs that offer converged services.

List some of the ISPs that you found in your search.

Comcast

Charter

AT&T

Step 2: Fill in the following form for the ISPs you selected.

Internet Service Provider Product Name of Converged Service
Comcast Xfinity Triple Play
Time Warner Cable TV, Internet, and Phone
AT&T AT&T U-Verse

Part 3: Researching Local ISPs Offering Converged Services

In Part 3, you will research and find two or three local ISPs who offer converged services for the home in your geographic area.

Step 1: Research various ISPs that offer converged services.

List at least two of the ISPs that you found in your search.

Answers will vary based on geographic location.

Step 2: Fill in the following form for the ISPs you selected.

Internet Service Provider Product Name of Converged Service Cost per Month Download Speed
Comcast Xfinity Triple Play $89.99 Varies 10 to 16 Mbps
Time Warner Cable TV, Internet, and Phone $99.99 10 Mbps
AT&T U-Verse $59.00 3 Mbps

Answers will vary and will typically be based on price per month and relative priority of Internet speeds versus number of TV channels offered in the basic packages. Student may choose Comcast for higher download speeds for Internet. Emphasize to students that home users’ priorities can affect their choice of service. For example, users who stream movies exclusively may want higher download speeds versus a user who mainly does casual surfing of the Internet and checks email.

Part 5: Research Local Companies or Public Institutions Using Convergence Technologies

In Part 5, you will research and locate a company in your area that currently uses convergence technologies in their business.

Step 1: Research and find a local company using convergence.

In the following table, list the company, industry, and convergence technologies used.

Name of Company Industry Convergence Technologies
Cisco Systems, Inc. Information Technology Phone, Video, Data
Woodward, Inc. Aerospace Phone, Video, Data

Reflection

  1. Identify at least two advantages of using convergence technologies?
    _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
    Blending voice, video, and data signals onto one communication infrastructure allows companies to better manage the technology because the network will use a common set of rules and standards. The need for separate distribution equipment to offer voice and data will no longer be necessary.
  2. Identify at least two disadvantages of using convergence technologies?
    _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
    Until the technologies fully mature, configuration and management of voice, video, and data flowing on one channel can be a challenge. Giving voice precedence over data using Quality of Service (QoS) technologies can be quite complex for companies that do not have trained IT personnel on staff.
