Network Equipment Type
   Area Network Type       
   Your choices are...         
   Campus Area Network (CAN)       Campus area networks (CAN) are networks covering multiple local area networks (LANs) at universities, school districts or small business campuses. They are smaller than metropolitan area networks (MAN). 
   Enterprise Area Network (EAN)       Enterprise area networks (EAN) are networks that securely connect all locations for business networks.  
   Local Area Network (LAN)       Local area networks (LAN) are networks that connect a group of computers and devices, such as printers or scanners, over short distances. 
   Metropolitan Area Network (MAN)       Metropolitan area networks (MAN) are networks that connect devices over medium distances, such as a town or city. They are larger reaching than local area networks (LAN) but smaller than wide area networks (WAN). 
   Storage Area Network (SAN)       Storage area networks (SAN) are dedicated networks that connect storage devices to other storage devices. 
   Wide Area Network (WAN)       Wide area networks (WAN) are networks that connect devices over large physical distances, such as the internet. 
   Wireless Local Area Network (WLAN)       Wireless local area networks (WLAN) are networks that connect devices wirelessly over short distances, similarly to local area networks (LAN).

Modem Type
   Modem Type:       
   Your choices are...         
   Cable Modem       A cable modem is a device that connects a device to the internet by a coaxial cable.  
   Cellular Modem       Cellular modems provide wireless data communication over worldwide cellular networks. 
   xDSL Modem       Digital subscriber lines (xDSL) are a set of technologies that use sophisticated modulation schemes to send data onto copper wires. They are called the last-mile technologies because they are used only for connections from a telephone switching station to a home or office, not between switching stations. xDSL is similar to ISDN. Both operate over existing telephone wires and both need a short connection (less than 20 ft.) to a central telephone office. There are several types of xDSL technologies in use today such as ADSL, SDSL, HDSL:
  • Asynchronous DSL (ADSL): Supports data transfer rates of up to 9 Mbps when receiving data (upstream), and up to 640 Kbps when sending data (downstream).
  • Symmetric DSL (SDSL): Supports data transfer rate of up to 3 Mbps in both directions, upstream and downstream.
  • High data-rate DSL (HDSL).
 
   ISDN Modem       Integrated services digital networks (ISDN) is an international standard used to send data, video and voice over digital telephone lines or normal telephone wires. ISDN supports data transfer rates of 64 Kbps. Normally the telephone company installs two lines called B channels; both can be used to send data to achieve data rates of 128 Kbps. A broadband version of ISDN, called B-ISDN, supports data rates of 1.5 Mbps over fiber optic cables. 
   Radio Modem       Radio modems are radio frequency transceivers for serial data. Each device connects to a serial port (e.g. RS232) and transceives signals from another matching radio modem. 
   Telephone (PSTN) Modem       Public switched telephone network (PSTN) refers to the international telephone system based on copper wires carrying analog voice data. This is in contrast to newer telephone networks based on digital technologies, such as ISDN or FDDI.

Features
   Features       
   Your choices are...         
   Ruggedized       Hardened products are designed to withstand extreme conditions. Their casings provide protection from weather-related conditions and can act as a heat sink, directing high temperatures away from sensitive components. Hardened products use more reliable components than commercial products and are often used in telecommunications applications. 
   Integrated Firewall       The network equipment has an integrated firewall for security. 
   IP Telephony / VoIP       IP telephony allows voice phone calls to be made over the Internet or other packet networks using a personal computer (PC), via gateways and standard telephones. 
   Internet of Things (IoT) Compatible       The device is compatible with the Internet of Things (IoT) network. 
   Layer 3 Capable       The network equipment is layer 3 capable, or has IP addressing, for smarter routing. 
   Power-over-Ethernet (PoE) Ready       The device supports power over Ethernet (PoE) signals. Both data and power are delivered in one cable to a powered device (PD). 
   VPN       A virtual private network (VPN) is a connection that has the appearance and many of the advantages of a dedicated link, but occurs over a shared network. Using a technique called tunneling, data packets are transmitted across a public, routed network in a private "tunnel" that simulates a point-to-point connection and allows network protocols to traverse incompatible infrastructures.
