dsl vs cable a broadband study

DSL Vs Cable 11-7-98 Dedicated to Frank the Math guru @Ameritech "

Remember cable is only one wire and a shield that has a shared pipe or line. You don't share your phone wires with the house next door. Your regular old phone line with ultra high frequency's is yours private line from end to end . The best ! ! .

IF Cable is all you can get .................Get it But if ( ? ) you can get ether one read some Please

PRIVACY You don't share your phone wires with your the house next door .Remember cable is only one wire that has a shared pipe or line .Your regular old phone line with ultra high frequency is yours private pipe or line from end to end. The best !

Web Hosting and single server Mass Virtual hosting is only on DSL not on cable. You can not have a ISP type service on cable . Under current terms you are not allowed to post DNS on your home or office system on Cable. See if your local provides you this service for you our you can do it yourself ? The answer is "no". Hosting at your home or business is a must for starting company's .

Flexibility We have increased our band width and decreased our bandwidth. They were completed in good time with great flexibility. DSL is the true winner for office use on internet servers. On cable the speed is always good "in optimum conditions" but not flexible . Small business's at office or home can greatly benefit from this advantage . DSL package's offer 144/1.0 144/1.5

DSL's router's advantages are greater than cables because it uses one transport protocol type ( Ethernet ) Cable uses two transport protocols Vs DSL one protocol . DSL uses primarily a static IP addressing system giving 1-5 1-10 1-32 1-64 and up . Dynamic is more secure as each individual router is the physical gateway that rotates its SINGLE IP address . Cable is often large groups of IP's all assigned to the same gateway .This creates a bottle neck for the whole system.

Static IP's Address 1 to 255 DSL routers can be programmed with up to 255 addresses, where as a cable modem can only be addressed with one IP address on a Dynamic DHCP addressing system. This is a severe limitation for any one who needs more than one IP's. A cable modems IP will change so it is NOT static no matter what anybody says DSL your IP never changes That is a static Address . DSL packages have from 255/128/56/13/5 group range IP's address to work with. This is a reliability that that is built into the systems

Small Business Demands DNS WWW SMTP + a host of others at your finger tip's . We you have the server a your home or company's office. This will provide you "a starting new company" The edge you need for a constant web exposure at very mane gable prices . This offers a accelerated leap onto the internet . This is the Physical machine that will answer your companies name or IP number or domain name. This can be a PC with front page server, all the way up to a Linux/NT one's like I use in my studies . A main aspect of an internet sever is "DNS" Domain Name Server SMTP simple mail transport post office, and web services which are very costly to those who have to deal with it on a large and small scale. This is one example of DNS savings. With this DSL and a Linux or NT operating systems you can setup a domain for $35.00 with your IP number. $70.00 is the normal fee for registering without a permanent IP address. In 15 minutes from your home you can register domains with www.networksolutions.com . That is a $100.00 savings alone on one service. After your domain is online you will have total control of that important service. Changes anytime !

Redundancy DSL placed in the hands of the phone companies of America, have a far greater advantage of giving a dedicated band width through their switching systems with optic fiber backbones. Examples of DSL systems below.

Cables which are on a shared redundant OC3 backbones using older TCP/IP (10 base T) methods for transfer of data rather than over newer and faster proven category 5 systems ; there is no comparison to a 100mip systems. ( twisted pair).

Category 5 systems and DSL are integrated into the local phone companies systems now. Category 5 systems are LAN (local area network) 10 up to 100 megs. You might work at a firm or office that use's a LAN for all it computers and if its not cable, its upgraded to category 5 90% better.

You are a ISP at that point ! Total internet control. You can setup your home office and manage your websites even have your own Email server .You can add as many customers&friends Email accounts as you like.

With one phone line, I can host as many domains as the bandwidth can support and when I have grown my DSL lines will grow with me all the way up to OC3 . Cable will not permit you to set to any ISP type futures . Though Cable has added some very nice speed packages so you can get a 1.5/128 or a 768/128 at very good prices.

DSL will give you the freedom to expand as you need it with minimal upgrade cost, which are applied to your phone bill. You pay for dedicated speed and you get it and it is even "guarantied"

Combined Bandwidth If I add another DSL in to my home/office these two lines can be combined to give guaranteed additional band width. Example: 1.5+1.5 = 3 million bits per second of guaranteed band width. Compared to cables 128k max upload and ???? download no combining of Cable connections will increases your speeds but with DSL this is a reality you can get that combination what ever the speed "guaranteed or your money back in some cases".

Some History The technology for eight wires (cat5 system) is the best the world has seen yet for data transfer over copper wires. DSL has used this same technology in two wires to get almost 6 megs per second in a single twisted pair . Just ask UCLA N.A.S.A. or JPL or MIT and many others why they will say it is the best after all it was there devolvement and dedication to this for N.A.S.A. The average T1 line in this study was $209.00 to $425.00. Phone companies can provide redundant systems 1000 times that of any cable . Why because your phone wire are yours. from your home all the way to the first main switching unit for distribution or dedicated nodes that are assigned to you !. Lots of dishonest people STEAL or TAP IN on cable. This does not happen on phone lines today. ATM ( automatic teller machines) are run by phone companies not cable companies . We use a HDSL 6 wire.

HDSL (High Bit/Data-Rate DSL): Symmetric (same speed download/upload: 1.54Mbps) Uses two copper twisted-pair lines. A replacement for T1/E1 repeater systems, due to the equivalent speed. Also originally designed for video data. No compression, and less fault tolerance. (A faster version uses 3 twisted pairs, and HDSL-2 uses only 1 pair.)

DSL is often referred to as twisted pair Two wires. This means that one line is listening TR (transmit receive) to the other talk TX (transmit send) and talk TX is sending to one that is listening TR . Cable is coax 10base T with one wire with a shield that is not used in data transfer this means that one wire has two jobs TR and TX and with a fluctuating speeds and errors . So what is the differences in speed twisted pair can send 100 megs a second 10base T is 10 megs a second no matter how hard the cable company's try to send up to 900Mhz in a line that is a mismatch at 75ohm. It should be 50ohm minimum cable for data to be efficient and reliable. Cable companies need to agree on a modem or router that does not have an open ended speed to remove some of the immediate fluctuation occurring on cable systems today. If cable companies want the answers for the currant problems they lye in radio research and FCC archives and Bell Labs. See network for cable below. Cables limited network Example's shown here as in use today has its problems its shared. They are currently splintering the large areas of buss and ring type cable networks . And one DSL Diagram "not shared"

This is based on a private combined study of every "cost effective" service for office or home use of servers and PC's that can be maintained at a very low cost and high reliability. Bandwidth that can be modified as needed . All services mentioned in this this article will be re-visited on 10-3-01 for current updates in this study.

UPDATE .........................10/06/01..................................................................

change's in favor of cable hardware and vendors are making great advancements. They are so different in performance from the quest to find a answer to the giant systems main problem the all in one ( single gateway) When they finely figure out how to splinter out large groups in each area that will be a fine start this will give more privacy and reliability . answers a abound in this students head . Here's One type of modem/router is the 3com their in front in my studies there router is three times faster for Cable than other Brands currently available.

Cable companies will still need to create a closed circuit environment for 10 bases-T type of data transfers with uhf, vhf ,digital, analog all mixed together and a industry does not support of standard protocol in a coax cable in use. Example your PCI card interface is a standard in the mid 80's ISA was born industrial standard architecture. The manufactures need to come to some standards in the same way for Cable. 03/00

ON CABLE

Cable is a high speed access , or for home or office use we have seen speeds of 4 megs a second their is little doubt witch one is faster its DSL. With Cable you have limitations on hosting or relying on a IP that change .And as far as the speed goes . you need to be in right place at the right time I have seen a 128k to 264k averages to 4Megs . Now lets talk Turkey now its 4Megs down "but" your will never get over 128k uploads you are bound at the modem so that means you have a fluctuating down and a poor uploads.

UPDATE ON PC SHARING there are a number of very easy to use and very reliable this is a wonderful advancement in creating user friendly home network setups so you will need to go the extra mile to secure your cable connections. Be sure to see the new net gear and 3com's cable modems and DSL router with internet sharing all ready built in so you share a single IP.



The limitations of the (stock ) router or modem and it's connection to the digital broad band service has been prone to digital lock up, packet loss, and DNS errors. This technology is in need of improvement over all areas of reliability. The manufactures of the new types of hardware like these routers/modem provided by the cable companies should have a common protocol to regulate speed and with the hardware manufactures so the fluctuations are less frequent and this may be the answer ! Cable is combining two protocols to complete what DSL does in one ultra high frequency on Twisted pair (your phone line).
I have used a frequency counter to see the difficulties on separation of TV & Data by using low pass filters, and high pass filters, at a point that is very complicated. The point of your wall tap, input wall outlet. I have made these pass filters by hand for myself in Radio use's from 3Khz' to 1.2 GHz. A signal generator and 1 digital spectrograph and a frequency counter were used in this study to see first hand of the problems.
As Cable technology grows the need for better equipment will not be met by cable companies nation wide for some time. Even after they solve the problem of equipment and venders, they can not make staff of cable installers to understand how to provide the public with reliable services until a massive retraining of closed circuit environments takes place, They will still be battling guaranteed bandwidth from open ended speed on the modems. A protocol is needed. In a normal house a TV on a splitter gets you a slower speed. These splitters need to be redesigned so that as the length of the cable's increase or decrease will be matched for proper dB lose. and separation of TV and data
A simple way to improve any system is to terminate every open outlet with a 75ohm terminator that will increase the circuit.
In one study We watch this in a house with many out lets and with low signal, this equals poor/ok service. And After 13 month of service this has not improved .
This study has found that for all practical purposes, For supplying the public with this Free comparison is to explain the differences that exist between DSL and Cable. And with the hope that the push to get high speed internet access for all people will benefit all the world.
my studies are a combination of my education in electrical circuitry micro, fiber, digital and networking TCP/IP IPX SPX and net bios applications and its uses. I am also a ham radio operator with a high interest in all aspects of data in a phone, cable, fiber or airwaves for advancement for all.
