ATM technology integrates voice, data and video at the same time. ATM uses fixed size packets called cells of 55 bytes in length. ATM network is a high speed circuit switched network that is capable of transferring one million signals using ATM protocol. ATM is a connection oriented technology in which logical connections are established for the data communication. ATM is implemented in the WAN and telecommunication sectors. Small data cells are used for communication and ATM is designed for high speed and high traffic networks. ATM cells allow voice, data and video transfer at the same time. ATM operates on the data link layer of the OSI model and it uses UTP/STP, fiber optic or air as a communication medium.</td></tr>

<div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><strong>ATM CELL BASE</strong></span></div><div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">It is a small unit of 55 bytes fixed length and it contains the users and signaling information in it. It has a header with very limited functionality to reduce the internal buffer and to provide the high speed transfer. ATM cell identify the cells that belongs to the same virtual channels and perform easy routing.</span></div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;"></span></span><br />
<div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;"><strong>ATM SWITCHING</strong></span></span></div><div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;">Various switching technologies have been developed in the past to provide the high speed data transfer and secure communication. ATM switching technology provides high speed data transfer due to the connection oriented technology. ATM switching technology uses the predefined routing table so guarantees the fast data communication.</span></span></div><div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;"><strong>ATM DEVICES</strong></span></span></div><div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;">ATM basically uses two types of devices such as ATM switch and end systems. The function of the switch is to handle the transmission of the cells throughout the network. Switches accept the incoming cells from the ATM end station or another ATM switch. On the other hand, ATM end systems contain the ATM adaptors.</span></span></div><div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;"><strong>ATM CONNECTIONS</strong></span></span></div><div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;">ATM supports two types of connections point to point and point to multi point connections. In the point to point connections, two end systems are connected bi directionally or uni directionally. The point to multi point system connects one source to the number of destinations in uni directional. The source sends the information and switch replicates it to the destinations. Unidirectional network connects two switches. A typical ATM network consists of a set of the switches interconnected by point to point links. Switch support two types of interfaces user network and network node interface. Asynchronous transfer mode technology is designed for the reliability, performance, utilization and QOS and it creates fixed channels and routes when data travels between two points. There are four types of the choice when purchasing a connection.</span></span></div><span class="Apple-style-span" style="background-color: white; font-family: Arial, Helvetica, sans-serif;">Constant Bit Rate: It specifies fixed size rate and data is transferred in a steady form. Variable bit rate.</span><span class="Apple-style-span" style="background-color: white; font-family: Arial, Helvetica, sans-serif;">Variable Bit Rate: It provides specified throughput and it is best for videoconferencing. </span><span class="Apple-style-span" style="background-color: white; font-family: Arial, Helvetica, sans-serif;">Available bit rate. It provides guaranteed minimum capacity but high rate is also possible when the network is free. </span><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;"></span><span class="Apple-style-span" style="background-color: white;"></span><span class="Apple-style-span" style="background-color: white;"></span></span><br />
<div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;">Unspecified bit rate. It does not provide any fixed throughput level and it is best for the file transfer where delay can occurred.</span></span></div><div style="text-align: justify;"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: white;"><strong><br />

Saat itu saya belum pernah merasakan internet dengan speedy, tahu-tahu diminta bos untuk membantu men-setup modem adsl di Kopegtel (Koperasi Pegawai Telkom) di jalan Kartini. Modemnya merek linksys, tipenya mungkin ADSL2MUE, pada link tersebut terdapat manual untuk konfigure modem tersebut untuk mode bridge (winxp).</span><span class="Apple-style-span" style="background-color: white; color: #333333; font-family: Arial, Helvetica, Georgia, sans-serif; font-size: 12px; line-height: 18px;"></span><br />

Setelah login melalui <i>web configuration</i>, saya lihat banyak sekali fitur yang ditampilkan sampai saya bingung sendiri <img alt="-)" class="wp-smiley" src="http://awarmanf.wordpress.com/wp-includes/images/smilies/icon_smile.gif" style="background-attachment: initial; background-clip: initial; background-color: initial; background-image: none; background-origin: initial; background-position: initial initial; background-repeat: initial initial; border-bottom-color: rgb(221, 221, 221); border-bottom-style: solid; border-bottom-width: 0px; border-color: initial; border-left-color: rgb(221, 221, 221); border-left-style: solid; border-left-width: 0px; border-right-color: rgb(221, 221, 221); border-right-style: solid; border-right-width: 0px; border-style: initial; border-top-color: rgb(221, 221, 221); border-top-style: solid; border-top-width: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" /></div><div style="padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 10px; text-align: justify;"><span></span></div><div style="padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 10px; text-align: left;">Yang pertama saya baca-baca adalah seting koneksi untuk speedy, tidak ada yang saya mengerti di sini <img alt="-?" class="wp-smiley" src="http://awarmanf.wordpress.com/wp-includes/images/smilies/icon_confused.gif" style="background-attachment: initial; background-clip: initial; background-color: initial; background-image: none; background-origin: initial; background-position: initial initial; background-repeat: initial initial; border-bottom-color: rgb(221, 221, 221); border-bottom-style: solid; border-bottom-width: 0px; border-color: initial; border-left-color: rgb(221, 221, 221); border-left-style: solid; border-left-width: 0px; border-right-color: rgb(221, 221, 221); border-right-style: solid; border-right-width: 0px; border-style: initial; border-top-color: rgb(221, 221, 221); border-top-style: solid; border-top-width: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" /> , kecuali login speedy dan ini dia fungsi <a href="http://en.wikipedia.org/wiki/Network_bridge" style="color: #105cb6; text-decoration: underline;" target="_blank" title="Network bridge">bridge</a>, jadi modemnya bisa berfungsi sebagai bridge mirip modem eksternal yang biasa dipakai untuk dial ke isp. Pokoknya diterima apa adanya dulu deh. Lantas saya lihat fungsi <a href="http://en.wikipedia.org/wiki/Internet_firewall" style="color: #105cb6; text-decoration: underline;" target="_blank" title="Firewall (Networking)">firewall</a>, nah ini dia yang bisa saya otak-atik. Yang diinginkan pertama adalah mencegah <a href="http://en.wikipedia.org/wiki/Icmp" style="color: #105cb6; text-decoration: underline;" target="_blank" title="Internet Control Message Protocol">icmp</a> dan <a href="http://en.wikipedia.org/wiki/Smtp" style="color: #105cb6; text-decoration: underline;" target="_blank" title="Simple Mail Transfer Protocol">smtp</a> keluar dari client karena virus brontok suka ping ke domain internet dan mencegah virus dari client kirim email. Selain itu juga saya batasi hanya beberapa ip client yang bisa konek internet. Setelah save dan reboot modem, ternyata hasilnya mengecewakan, beberapa client bisa konek dan ada yang tidak. Saya masih belum tahu salahnya dimana, lagian keisengan setup modem linksys tsb terbatas waktunya karena saya harus balik ke kantor dan lagipula saya tidak mau direpotkan apabila dapat keluhan dari pengguna. Jadi saya balikin deh seting modem tsb ke default.</div><div style="padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 10px; text-align: left;">Sejak saat itu saya terobsesi bagaimana membuat modem adsl bisa jalan sebagai bridge di mesin linux. Khusus modem <a href="http://www.adslguide.org.uk/hardware/reviews/2005/q4/linksysADSL2.asp" style="color: #105cb6; text-decoration: underline;" target="_blank" title="linksys ADSL2MUE">linksys ADSL2MUE</a> ini rupanya sudah ada driver bridge untuk mesin windows. Kesempatan itu akhirnya datang setelah kantor saya jadi berlangganan speedy, itu pun setelah saya provokasi agar pakai speedy daripada pakai telkomnet instan (tni) yang koneksinya tidak bisa dijamin, sudah konek tapi tidak bisa browsing internet, baru bisa browsing setelah beberapa kali konek <img alt="-(" class="wp-smiley" src="http://awarmanf.wordpress.com/wp-includes/images/smilies/icon_sad.gif" style="background-attachment: initial; background-clip: initial; background-color: initial; background-image: none; background-origin: initial; background-position: initial initial; background-repeat: initial initial; border-bottom-color: rgb(221, 221, 221); border-bottom-style: solid; border-bottom-width: 0px; border-color: initial; border-left-color: rgb(221, 221, 221); border-left-style: solid; border-left-width: 0px; border-right-color: rgb(221, 221, 221); border-right-style: solid; border-right-width: 0px; border-style: initial; border-top-color: rgb(221, 221, 221); border-top-style: solid; border-top-width: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" /> . Yang datang ke kantor bawa modem speedy rupanya orang telkom yang dulu saya temui sewaktu di Kopegtel Kartini, karena sudah mengenal saya, dia memberikan saya modem adsl yang masih terbungkus agar disetup sendiri.</div></span><span class="Apple-style-span" style="background-color: white; color: #333333; font-family: Arial, Helvetica, Georgia, sans-serif; font-size: 12px; line-height: 18px;">Sewaktu dibongkar, ternyata modemnya adalah <a href="http://dareglobal.en.ec21.com/GC00530386/CA00530507/ADSL_Modem.html" style="color: #105cb6; text-decoration: underline;" target="_blank" title="Modem ADSL DareGlobal DB108-E">DareGlobal model DB108-E</a>.

Modem dikonekkan ke link adsl dan ke server linux pakai <i>cross cable</i>, terus dinyalakan. Waktu itu saya belum setup login speedy di modemnya, iseng-iseng nge-ping dns telkom, eh kok ternyata tembus, wah dapat koneksi speedy gratis nich :d .</span><span class="Apple-style-span" style="background-color: white; color: #333333; font-family: Arial, Helvetica, Georgia, sans-serif; font-size: 12px; line-height: 18px;"><div style="padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 10px; text-align: left;">Masa gratisnya cukup lama, dua minggu lebih.

Caranya mudah, untuk ini kita perlu komputer dengan OS windows, install driver yang dibutuhkan untuk koneksi ke modem melalui port usb, kemudian konfigur ip address windows dengan ip addres selain 192.168.1.1. Jadi meski modem tersebut sedang konek ke speedy dan user-user sedang browsing internet kita bisa monitor dsl statusnya.</div></span>
