Devices

Below are descriptions of the different devices involved in wireless installations.

  • CPE:

    CPE 1        CPE 2     CPE 3
     
    Client Premises Equipment - refers to the device outside the building on your premises that creates the wireless connection to our network. Most modern CPE’s are integrated devices and contain the following three aspects or functions:
    • Antenna - that directs the wireless signal to a True Technologies AP (Access Point)
    • Wireless radio - the device that produces the wireless signal and does the encoding and decoding of IP information onto the wireless signal.
    • Router - the CPE also acts as a router between the True Technologies IP network, and the client’s private IP network. By default the router is set up to be a NAT (Network Address Translation) router, meaning that all the IP information inside the client network will be sent to the True Technologies network “hidden” behind a single “public” IP address. The router will also act as a firewall protecting you from the outside.
    The CPE will also provide the following:
    • DHCP (Dynamic Host Configuration Protocol) server - the CPE will manage the internal network and provide IP addresses to devices connecting to the client network. It can, if required be disabled.
    • DNS and Gateway - the CPE will also be the client network’s DNS relay (Domain Name System - the translation of domain names to IP addresses) as well as its Gateway.
    • The CPE could also perform extensive firewall as well as other high level network and routing functions. If the need is there for such possible functions, it can be discussed with your local call centre.
    The CPE can consist of either 1 integrated unit, or of a combination of various equipment. Access to the CPE is prohibited to True Technologies only through normal username and password protection.
  • POE:

    POE

     
     
    Power Over Ethernet - refers to a device that sends low power DC electricity to the CPE imbedded in the UTP communication cable. It normally plugs into a 220V power plug inside the premises, and feeds 2 UTP cables: one that transports electricity and communication to the CPE, and the other that transports communication to the internal network.
  • Switch:

    Switch

    Used to connect IP network devices with each other through UTP cable, like computers, printers, etcetera.
  • SIP ATA:

    SIP ATA

    Session Initiation Protocol and Analogue Terminal Adapter.
     
    SIP refers to the protocol used when transporting a telephony signal across an IP network. Also referred to as Voice Over IP or VOIP. ATA refers to a device converting a SIP IP signal into an analogy telephony signal, thus enabling normal analogy telephone handsets to communicate on a SIP IP network.
     
    For clients that have existing analogy devices and would like to keep using then, a SIP ATA would be used.
  • VoIP Phone:

    VOIP Phone VOIP Phone 2

     
    Refers to a telephone handset, either desktop or portable, which connects directly to an IP network and registers directly to a SIP server. Because this is a digital device it has benefits way beyond analogy devices, in terms of audio quality, functionality and usability.
  • FAX ATA:

    FAX ATA

     
    Refers to a device that connects an analogy fax signal to be transported over an IP based network. Fax over IP is much more complex than analogy faxing and also requires a much more stable network than just normal VOIP. Because of this True Technologies uses a Fax ATA system that does not physically rely on a call being made over the IP network, creating a very stable Fax solution.
     
  • WIFI Router:

    WIFIWIFI 2

    Refers to a device broadcasting a short range wireless signal based on the IEEE 802.11 b/g/n standard - commonly referred to as WiFi. The purpose of Wi-Fi is to grant wireless access to other 802.11 enabled devices, such as laptops, tablets and smartphones. True Technologies normally configure these Wi-Fi access points as bridged devices and not as routers, as the CPE already does all the neccesary routing.
