Internet Info: Telephone Calls Over The Net
By Bob Brand
The day will come when you will be able to place a local (toll free) call to
your Internet Service Provider (ISP) and connect to phones all over the
country. The technology is here now.
The phone line in your home is called a POTS (plain old telephone service)
line. There is a copper wire running from your house to the telephone company
CO (Central Office) or SLC (serial line concentrator). From there, the
telephone network uses glass fiber. Office buildings have very few POTS lines
(only for modems and FAX machines) and have digital phone signals running
between the offices. A business will have a PBX (Private Branch eXchange)
somewhere in the building that handles the telephones. The PBX receives
incoming phone calls (they are digital signals remember) and routes them to
the proper phone within the building.
Digital means ones and zeros. This is not magic. With your home phone, the
POTS signal (non-digital) is changed over to digital (ones and zeros) at the
CO or SLC. The Internet is all digital. The information moves around the Net
with TCP/IP (transmission control protocol/Internet protocol). In many cases,
the Internet uses telephone lines to accomplish the task. The ISP is connected
to the BIG network (the Internet) so it is only a small leap for people to
access the Internet Network instead of the phone network for phone calls. The
only thing holding this back is equipment. Soon that will change.
Enter TouchWave
TouchWave Inc, a Denmark-based company, has set up offices in Silicon Valley,
Palo Alto, California. They recently released WebSwitch, a product that can
replace the PBX switch. For about $8,500 a business can install WebSwitch,
allowing 16 phone line extensions plus connection to a LAN (local area
network).
The phone company would have to replace the copper wire coming into the PBX
and connect to WebSwitch. Small companies often have significant phone bills.
This could be a real cost saver. In addition, there is equipment available
that will allow PBX calls to be routed over the Internet.
You can see that the next step is for an ISP to install this type of
equipment. The ISP holds your on-ramp to the Information SuperHighway. Thus,
if you have the right type of equipment in your home, you make a local phone
call to the ISP, then tap in a few more numbers and the call goes through.
What About
The Phone Company?
The first question that comes to mind is: "Why, if this is so easy, don't the
phone companies have a lot to lose?" Sure they do. That is why SNET has moved
aggressively into the Internet Service Provider business along with NYNEX/Bell
Atlantic and other RBOCs (Regional Bell Operating Companies). Local phone
service is now open to competition. This will mean that you will have a choice
in phone service to your home. By the way, if the phone companies drag their
feet, the cable television providers, who may already have a fiber cable
coming into your TV set, can step in.
Is there a down side? Sure, the quality of the digital phone will not be as
high as what you are getting now. If the trade-off is between "hearing a pin
drop" and saving a few dollars on long distance phone charges, which will you
choose? However, before we get to that type of choice, more equipment will
have to be in place first. The good news is that the equipment is available
for purchase and the prices are dropping. It is only a matter of time before
we see tangible results.
The Internet continues to change at a breathtaking pace. Telephony over the
Net for most of us with home computers should be more widespread within the
next several years. These are exciting times.
