In the modern organization as a workplace, and in many cases, leisure after work, have virtually become an integral part of the means of information transfer. Yes and no denying the fact that the possession of the necessary knowledge in our time is similar to the physical possibility of movement of a living organism. Suggestive phrase 'movement is life' can be supplemented with 'a life - is information.' It was in this environment, information is the dependence modern man. To solve the questions of the organization fast, reliable connection from the beginning of the last century using wired channels.
It is this method still remains the most functional and reliable quality, and digital modems are now made inexpensively by using already available in almost any terrain two-wire communication lines, to organize a point of access to corporate channels or the Internet, without depriving the consumer is already installed on this line analog telephone. The most promising technology currently has ADSL, to turn the twisted pair telephone wires in a tract of high-speed data transmission. ADSL line connects two modem ADSL, which are connected to each end of the phone cable. The main constituents of the organization ADSL - connections are the DSLAM (the device on the provider), ADSL-modem (the device on the user side), or twisted-pair telephone cable. In this case, organized three information channels - outgoing digital data from the user of incoming digital data and channel the regular telephone line (POTS).
Telephone channel is allocated using filters, which guarantees the performance of your phone, even in an emergency connection ADSL. In data transmission technology is asymmetric - the speed of incoming flow, etc. Data that is transmitted in the direction of the end user is higher than the rate of outgoing flow, ie transmitted from the user towards the network. But at the same time, the speed of data transmission from the user is still significantly higher than when using an analog modem. In fact, it is much higher than in the channels of ISDN (Integrated Services Digital Network - Digital Network Integrated Services). Conducted a small quantitative comparison of communication technologies.

Analog modems can transmit data at speeds ranging from 14.4 to 56 Kbps. ISDN provides a data rate of 64 kbps per channel (usually the user has access to two channels, a total of 128 kbit / s). Various DSL technologies enable the user to transmit data at speeds of 128 Kbps (IDSL), 768 kbps (HDSL), 'downward' flow of 1.5 - 8 Mbit / s and bottom-up flow of 640 - 1,000 Kbps ( ADSL), 'downward' flow of 13 - 52 Mbps, and 'bottom-up flow of 1.5 - 2.3 Mbps (VDSL).
Cable modems have a data rate of 500 Kbps to 10 Mbps. (It should be borne in mind that the bandwidth of cable modems is shared among all users, while having access to that line.
Therefore, the number of concurrent users has a significant impact on the real data transfer rate of each.) Digital lines E1 and E3 have a data transfer rate, respectively, 2.048 Mbps and 34 Mbps. ADSL technology enables data transfer at speeds up to 8 Mbps at a distance of 5.5 km on a single twisted pair of wires. Development of technology has led to the emergence of ADSL2 + speeds up to receive 24 Mbps and transmission of up to 2 Mbps. Hero of this review was a set of equipment provided by Ukrtelecom the ADSL Internet access, modem SmartAX MT880. With access to the equipment fairly well as a router and firewall, it can rightly be regarded as a compact hardware implementation of the access server to the network segment. This decision raises a new level of quality customer service, collected in a convenient and reliable device, all the new technological opportunities to build communication links.
Typically, they allow, with proper tuning of its fully protect against all kinds of intrusions, interference, hacking and attacks on information circulating or stored on your local network segment. Providing good data rate, due to relatively rapid filling, versatile solutions for small business and home networks can not even sophisticated users can easily take advantage of access to any information sources, corporate network or the Internet. The back side has a number of connectors and controls. Considering this pattern from left to right, first of all see the nest under the RJ-11 connector «ADSL» line - WAN interface of the modem is on LAN connector «Ethernet», then hidden in the body from being accidentally pressed the reset button «Reset», then go button power outage «Power» and finally the connector connecting an external DC source.

Reset (factory reset) by pressing the button «Reset» in retaining more than five seconds while the unit. ADSL modem / router SmartAX MT880 Huawei's can be recommended as a cheap solution for network access via ADSL, ADSL2, ADSL2 + channel through an HTTP connection PPPoA / PPPoE / IPoA / Pure Bridge / Bridged + DHCP / Bridged + Static IP with the possible speed up to 24 Mbps. Along with pretty good quality work and ensure proper functioning of the normal, this model has good support from the developer and a very nice price for a solution to such a level.
Its distinguish from the competition is easy enough to configure an interface with a complete, comprehensive solutions routing and firewall. Pros:. Very practical and rigorous design. Rather small and compact size. A small price for the decision at this level. Good speed data transmission. Easy to set up and functional WEB-interface.
Cons:. In some cases, the application changes are complete reboot the router. Lack of filtering by MAC address, and limit access to certain URL. Fairly high heat for a robot. At some point the normal work reconfiguring interfaces becomes impossible, helps complete reboot. Credits to Valery Parovyshnik.
