Are you looking to set up a simple network, a Unified Communications phone system, or Data Center connections? From small office connectivity to Enterprise class, New England Digital Computers can provide equipment from such featured vendors as Cisco, HP, Avaya, 3Com, Netgear and others.

From Switches and Routers to Wireless Access Points and Firewalls, NEDC can provide the equipment and expertise to get your network up and running.

Let’s take a look at some of devices used to create networks:

Switches are used to connect endpoints together. A simple network could consist of a single switch with several PC’s cabled to the switch. This is also known as a Local Area Network, or LAN. Several switches can be connected to create a larger LAN.

Another method of creating LAN’s is Wireless Access, using a device called a Wireless Access Point or WAP. This uses radio waves rather than cables to connect to the network. One of the benefits of a Wireless network is that notebook and other mobile device users can move through the facility while maintaining a network connection. WAPs are often connected together through switches.

As networks grow larger, congestion can occur with a large number of devices trying to communicate at the same time; when this occurs, or preferably beforehand, the network must be divided into different subnets. This can be done by segmenting the network with Routers or by creating Virtual LANs, or VLAN’s. VLAN’s, if supported on your equipment, can be configured on the endpoint or the switch. For VLAN’s to communicate with each other, they must be connected together with a Layer 3 switch or a Router.

A router is used to connect different networks together. These networks can be VLAN’s or real networks. Routers are also used to connect different media types of networks, as well as handling the hand off of the LAN to an Internet Service Provider, ISP, or Wide Area Network, WAN, carrier. A specialized version of a router, called a Firewall, is often used to block outsiders from connecting to the LAN. Firewalls can block this access as well as screening for virus and other unwanted software. This doesn’t eliminate the need for Anti-Virus software, but provides another layer of protection.

Unified Communications Systems, or UCS, allow customers to leverage their network investment to provide phone services over the network, eliminating the need for a PBX and allowing the customer to take advantage of Voice over IP or VOIP. VOIP providers can provide worldwide calling services at lower prices than the traditional telephone companies. Another advantage of VOIP is that it allows integration with many software applications.
