Whether your company is a small or medium-sized business, make your migration to Gigabit Ethernet Switch Installations and 10 Gigabit Ethernet faster and easier with INL Communications. We can provide, service & install Netgear, Adtan and Cisco switches. All our gigabit ethernet switches are tested for proven interoperability. With Gigabit Ethernet Switches and 10 Gigabit Ethernet Switch networking products, it's simple to bring the performance of Gigabit Ethernet and 10 Gigabit Ethernet to your servers, desktops and storage networks.
Tests and existing system have proved that you can get gigabit performance up to and over 200 meters using existing CAT 5 cable. Furthermore- most Gigabit switches can get 200 meter gigabit performance using CAT 3 cable! However, INL Communications does not recommend using "CAT 3 cable" as in the future - other cabling standards (such as CAT 7 and beyond) may not be achieved over CAT 3 cable.
A revolution is taking place in today's network, just as 100BASE-T displaced 10BASE-T as the networking standard, now 1000BASE-T (Gigabit Ethernet over copper) is taking over as the most common type of networking installed. According to major industry analyst, worldwide sales of Gigabit Ethernet are already now exceeding those of 10/100 Ethernet. Gigabit Ethernet is not just for the enterprise anymore. Conscious buyers in medium and small businesses also see Gigabit as the best price/performance networking technology. As yet, no clear leader has emerged as the solution for this new type of Gigabit user.
INL Communicationshas been installing networks and switches in the Greater Washington DC Area for years. Gigabit ethernet switches are the only switches in the world that can deliver gigabit speed without rewiring that will save your company thousands of dollars. We can install a multitude of switches ranging from Cisco, Telco Systems, Allied Telesyn, NetGear, Adtran and many more. From layer 2 , to a layer 3 switches , to carrier grade switches.
In addition, we can install a switch that you provide at very competitive rates or offer you other switching solutions from other manufacturers- including refurbished - fully warranted switches. In either case you will be assured that INL Communications has the engineering expertise to do the job- on time- and within budget.

PoE, or "Power concerning Ethernet", is a technology which allows it to provide electricity with the use of a network cable. This technology is very skilful for small devices which only need a restricted flow supply.
This can concern about devices which only need one network connection and feeding such as acces points, cameras and IP phones. The electric signal is injected in the switch on the network cable. The commonly accepted standard for this is IEE 802.3af and these has been recognised by already many manufactures.
At the receiver 2 scenarios can take place: or the receiver supports PoE directly and the network cable can be linked, or this is not the case and there must be placed a transformer which will split up dates and the electric signal. Make allowance that the type of transformer always is product dependent (connector, voltage) Techne IT Solutions offer a total range to products in the field of PoE. This way the PoE injectors are, PoE 10/100 switch, PoE gigbit switch.
An Ethernet hub or concentrator is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single segment. Hubs work at the physical layer (layer 1) of the OSI model. The device is thus a form of multipoint repeater. Ethernet hubs are also responsible for forwarding a jam signal to all ports if it detects a collision.
Hubs also often come with a BNC and/or AUI connector to allow connection to legacy 10BASE 2 or 10Base 5 network segments. The availability of low-priced Ethernet switches has largely rendered hubs obsolete but they are still seen in older installations and more specialized applications
A hubbed Ethernet network behaves like a shared-medium, that is, only one device can successfully transmit at a time and each host remains responsible for collision detection and retransmission. With 10BASE-T and 100BASE-T links (which generally account for most or all of the ports on a hub) there are separate pairs for transmit and receive but they are used in half duplex mode in which they still effectively behave like shared medium links (See 10BASE-T for the pins specifications.)
An Ethernet hub, or repeater, is a fairly unsophisticated broadcast device. Hubs do not manage any of the traffic that comes through them, and any packet entering any port is broadcast out on every other port (other than the port of entry). Since every packet is being sent out through every other port, packet collisions result--which greatly impedes the smooth flow of traffic.
The need for hosts to be able to detect collisions limits the number of hubs and the total size of the network. For 10 Mbit/s networks, up to 5 segments (4 hubs) are allowed between any two end stations. For 100 Mbit/s networks, the limit is reduced to 3 segments (2 hubs) between any two end stations, and even that is only allowed if the hubs are of the low delay variety. Some hubs have special (and generally manufacturer specific) stack ports allowing them to be combined in a way that allows more hubs than simple chaining through Ethernet cables, but even so a large Fast Ethernet network is likely to require switches to avoid the chaining limits of hubs.
Most hubs detect typical problems, such as excessive collisions on individual ports, and partition the port, disconnecting it from the shared medium. Thus, hub-based Ethernet is generally more robust than coaxial cable-based Ethernet, where a misbehaving device can disable the entire segment. Even if not partitioned automatically, a hub makes troubleshooting easier because status lights can indicate the possible problem source or, as a last resort, devices can be disconnected from a hub one at a time much more easily than a coaxial cable. They also remove the need to troubleshoot faults on a huge cable with multiple taps.
Dual speed hubs
In their early days, Fast Ethernet switches were relatively expensive . However, hubs suffered from the problem that as simple repeaters they could only support a single speed. Whilst normal PCs with expansion slots could be easily upgraded to Fast Ethernet with a new network card computers with less common expansion mechanisms, or no expansion bus at all, and other equipment, such as printers, could be expensive or impossible to upgrade. Therefore, a compromise between a hub and a switch appeared known as a "dual speed hub".
Such a device essentially consisted of two hubs (one of each speed) and a two port bridge between them. Devices were connected to the appropriate hub automatically based on their speed and the bridge handled inter-speed traffic. Since the bridge only had two ports and only one of those needed to be 100Mbps it could be much simpler and cheaper than a full fast ethernet switch. Such devices have been rendered obsolete by the decreasing cost of fast ethernet switches.
