T1 Kbps
If you need to have a good, fast internet connection, there are many different choices for internet access in the world today, from conventional dialup to the increasingly popular broadband connection. There are some great T1 ethernet connections and T1 kbps solutions that can assist you in having a high speed internet connection. T1 cables have great ways to bringing you the fastest T1 access. Although one of the motivating factors for your high speed internet connection is cost, there are several advantages and disadvantages to each connection, and the decision boils down to selecting which access one best suits your needs.
Digital Subscriber Lines come in various flavors, most prominently ADSL (asymmetric) and SDSL (symmetrical). ADSL allows for a faster download speed than upload, and supports speeds of around 1.5 to 9Mbps downstream and16 to 640 T1 Kpbs upstream. SDSL allows for an upload/download speed of about 3Mbps. DSL allows more data to be sent over existing telephone wires by using a special DSL modem on your end and special hardware on the telephone companies' end to support the higher data transfer. This technology is limited by distance, and if you are too far from a central telephone office or switching station (usually farther than 20,000 feet), DSL will not be available to you.
Cable internet is another contender in the broadband market. This technology works by transmitting data over the same coaxial cables used to broadcast cable television. The data is received by a cable modem which plugs into a typical t1ethernet network card. These cables can support a higher bandwidth (10 Mbps) than conventional telephones lines, coupled with the fact that many houses are already wired for cable television make this a lucrative alternative for high speed internet connections.
Ethernet is not an access type so much as a network architecture developed by Xerox and refined by DEC and Intel. Ethernet networks support various speeds of data transfer. Initially supporting 10 Mbps, newer Ethernet specifications add support for 100 Mbps (Fast Ethernet), and 1000 Mbps (Gigabit Ethernet).
Wireless is network technology that interfaces with computers like t1 ethernet but transmits data over high frequency radio waves in the 2.4 Ghz range. Usually a wireless network card will transmit information to another wireless client or a wireless base station. Wireless base stations behave as gateways between the wireless clients and the wired t1 ethernet network. There are several competing wireless specifications referred to as Wi-Fi, HomeRF, and Bluetooth, respectively, neither of which are interoperable. At UMBC our wireless network supports the 802.11b specification (Wi-Fi) which can handle transmissions of up to 11Mbps with a good signal.
Keep in mind that dial up connections are established over conventional copper wire telephone lines, and require no equipment other than a relatively inexpensive modem. Once the modem is connected to your home telephone line, your computer dials the number to a internet service provider (ISP), where it connects to another modem (or bank of modems) and connects you that providers network. The advantage of dialup is that it is fairly easy to setup (just install the modem, and use the Windows or Mac Internet connection wizard, or sometimes an internet cd provided by your ISP) and also inexpensive. The drawbacks are that since modems communicate over telephone lines they are subject to line noise, and data speeds are restricted to a practical limit of about 53 kilobits per second. Additionally, if you wish to use the internet and make telephone calls simultaneously, you will have to install a second telephone line.
There are two popular choices when it comes to broadband or "high-speed" internet services, DSL (digital subscriber line) and Cable. Either of these technologies allow you to gain a "instant"; permanent connection to the internet and use your telephone simultaneously!
