WAN	End User Connected Devices	These are collected separately by type of device on each tab, and they are a calculated field on the Peer Selection Survey. The high level definition is included here, and detailed definitions are included for each device type. An end user device is a device used by a user. The primary purpose of a WAN is to connect end user devices to each other, and to central resources such as servers and storage. The number of end user devices (EUDs) includes: All PCs, terminals, thin clients, PDAs, smartphones and tablets that can be connected to the LAN; All network connected printers; Wireless access points (count each as one end user device); The maximum number of concurrent Remote Access ports; Other user or customer peripheral devices such as ATMs, POS terminals, and so on. When a router is operated by IT on a third party premises, the number of EUDs for this router is 1. A typical example is when a Bank installs one of its routers on a clearing house premises, to guarantee secure communications. Do not include the following in the count of end user devices: Servers - Volumes for Servers connected to the WAN are collected separately in the Compute Tower Routers and switches (not usually in the hands of users). A Wireless Access Point (WAP) is a device that allows wireless devices to connect to a wired network using Wi-Fi or related standards conforming to IEEE 802.11. The WAP usually connects to a router (via a wired network), and can relay data between the wireless devices (such as computers or printers) and wired devices on the network. Concurrent Remote Access Ports refers to the number of simultaneous remote connections), supporting VPN or similar access
LAN	Active LAN Ports	An active port is a port on a switch or router that has been activated and/or enabled so that a device can use it. A port may be active even if it is not currently in use. For example, for organizations using hot-desking (or hotelling), LAN ports are considered active even if a user is not currently seated at the hot-desk (or hotel desk). A network switch or ”blade” (card) in a switch chassis is not considered active, if hard or soft MAC activity (e.g. applying power to switch); physically patching the switch; or applying policies (QoS or VLAN) for the network is required for its operation.
Voice	Handset	Handset is the end-point voice instrument used by a user for communicating with another party via a voice network (PSTN or IP). Includes handsets supported by PBX, Centrex, PBX Hybrid, Centrex Hybrid, VoIP and Soft Phones (the handset is a combination of a software application on a PC or workstation and headset/handset connected to the PC or workstation). The handset definition does not include: FAX machines, dedicated answering machines, voice mail systems or interactive voice response (IVR) systems.
