More About Used Cisco products and Pre-Owned Cisco products:

What is used Cisco? Used Cisco are Cisco Systems, Inc. network equipment products that are no longer being used by a network, and we refer to those products as gently used. Cisco Systems, Inc. is the largest manufacturer of network systems in the world, with leading CEO, John Chambers. Cisco network equipment dominates the router and switch market currently, and used cisco sets standards for all other companies and manufacturers of network equipment. With used Cisco network equipment, you can easily upgrade and adapt to new network configurations, while keeping cost at a fraction of what it would cost new. Of course, there is some Cisco equipment that can only be purchased new, but many, many Cisco products that are new to Cisco can be purchased from GGI Networks as used. Again, this helps IT budgets to be kept while at the same time, utilizing Cisco network equipment to its fullest - and when your network grows, you can grow with Cisco equipment. Cisco gear is compatible with most transport and access methods. We specialize in used Cisco, pre-owned Cisco, and we also provide new Cisco as well. Cisco products are durable, reliable, and resilient. We enjoy selling Cisco products and really enjoy what we do at GGI Networks, and we hope that it shows to you, our customers.

Network Definition: Cisco Routers

"A router is a computer networking device that buffers and forwards data packets across an internetwork toward their destinations, through a process known as routing. On a basic level, the router connects the user to a network, most likely the internet. Routing occurs at layer 3 (the Network layer e.g. IP) of the OSI seven-layer protocol stack" (Wikipedia). Used Cisco and refurbished Cisco routers can give you a competitive edge at keeping your operational costs down.

Network Definition: Cisco Switches

A switch is an important part of a network, because it is a device that segments networks into different subnets (or - splits the bandwidth). This switch can basically "switch" the bandwidth by dividing it for the purpose of several users at a location being able to have connectivity to a network by segmentation. Segmenting the network into different subnets keeps one network from overloading with traffic. "The network switch, packet switch (or just switch plays an integral part in the vast majority of current Ethernet local area networks or LANs. Mid-to-large sized LANs contain a number of linked managed switches. A switch is a data link layer networking device. Switches perform transparent bridging (connection of multiple network segments with forwarding based on MAC addresses. Typical port speeds on an Ethernet switch are 10, 100, 1000 or 10000 megabits per second (Mbit/s), and half or full-duplex." (Wikipedia). Cisco switches help segment networks so that multiple devices can utilize the network.

Network Definition: Cisco Broadband

"Broadband is a transmission medium capable of supporting a wide range of frequencies, typically from audio up to video frequencies. It can carry multiple signals by dividing the total capacity of the medium into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies" (Verio). Basically, a broadband connection gives the user a broader band of connectivity to be able to handle higher-capcity IP traffic like video transfer and download for useres. Broadband networks use analog signaling over a wide range of radio frequencies and many cable companies offer high-speed Internet access over broadband systems. Used cisco broadband equipment like the Cisco UBR7246VXR, the Cisco uBR10012, and the Cisco uBR3x10 RF switch can greatly assist broadband companies and data centers alike in deploying broadband networks.

Definition: Cisco PIX Firewalls, Cisco ASA & VPN Security

"A firewall is a system which limits network access between two or more networks. Normally, a firewall is deployed between a trusted, protected private network and an untrusted public network. A firewall might grant or revoke access based on: user authentication, source and destination network addresses, network protocol, time of day, network service, or any combination of these. It might be implemented as an application level firewall or a packet level firewall. It might also implement a content filter, such as a virus wall" (M-Tech Identity Management). Cisco ASA Adaptive Security Appliances are also used to secure today's private networks. The Cisco ASA (Advanced Security Appliance) brings together in one device the benefits of the outdated PIX firewalls, and modernizes security by adding to its infrastructure tools that prevent unauthorized access on the OSI layers. Make sure to visit our section on used Cisco Firewalls and used Cisco ASA appliances. Cisco security appliances definitely cut down to almost nothing the amount of hacker related attacks and attempts while protecting your network.

Definition: Cisco VPNs - Virtual Private Networks

"VPN stands for Virtual Private Network. This creates a secure “tunnel” between the points within the VPN. Only devices with the correct "key" will be able to work within the VPN. The VPN network can be within a company LAN (Local Area Network), but different sites can also be connected over the Internet in a secure way. One common use for VPN is for connecting a remote computer to the corporate network, via e.g. a direct phone line or via the Internet" (Axis Communications). Cisco VPN appliances and equipment are very helpful in expanding bandwidth with virtualization features. Contact us today about used Cisco VPN network appliances.

Definition: Cisco VoIPs - Voice Over Internet Protocol

Voice over IP (VoIP) defines a way to carry voice calls over an IP network including the digitization and packetization of the voice streams. IP Telephony utilizes the VoIP standards to create a telephony system where higher level features such as advanced call routing, voice mail, contact centers, etc., can be utilized" (Cisco). "Voice over Internet Protocol, also called VoIP, IP Telephony, Internet Telephony, Broadband telephony, Broadband Phone and Voice over Broadband is the routing of voice conversations over the Internet or through any other IP-based network" (Wikipedia). Cisco VPN devices provide a digital sound resulting in a clearer reception, and cost-effectiveness by reducing long distance calls to internet connections.

Definition: Cisco IP Phones

"IP telephony provides a way for you to extend consistent communication services to all your employees, whether they are in main campus locations, at branch offices, or working remotely, or are mobile. IP telephony transmits voice communications over a network using open-standards-based Internet Protocol" (Cisco). Cisco's IP Phones are sleek, resilient, and assist in consistency with digital communications. Used cisco IP phones are cost-effective, save budgetary funds, and work very well.

Definition: Cisco Wireless

Wireless communication is generally considered to be a branch of telecommunications. The term wireless technology is generally used for mobile IT equipment. It encompasses cellular telephones, personal digital assistant (PDAs), and wireless networking. Other examples of wireless technology include GPS units, garage door openers and or garage doors, wireless computer mice and keyboards, satellite television and cordless telephones" (Wikipedia).
