1. DECT

   Is a digital wireless technology that is being used for local cordless coverage in both home and corporate phone systems. A very flexible standard, it can be applied to cordless PBX, wireless local loop, and dual mode GSM/DECT systems.

2. Default Error Pages

   Web: Default Error Pages are generic pages that pop up advising the user that a url that has been called to view is not available/inaccessible etc. A “custom error page” is a feature of most Web server software that allows users to replace default error messages with ones they create. The default error messages tend to be fairly generic, and not particularly user-friendly, so making custom messages for your site is sometimes recommended.

6. DSLAM

   A digital subscriber line access multiplexer (DSLAM) delivers exceptionally high-speed data transmission over existing copper telephone lines. A DSLAM separates the voice-frequency signals from the high-speed data traffic and controls and routes digital subscriber line (xDSL) traffic between the subscriber's end-user equipment (router, modem, or network interface card [NIC]) and the network service provider's network.
