Aastra DECT MBU 400 Mobile Unit

Access Point
A station that transmits and receives data (sometimes referred to as a transceiver). An access point connects users to other users within the network and also can serve as the point of interconnection between the wireless LAN and a fixed wire network. Each access point can serve multiple users within a defined network area; as people move beyond the range of one access point, they are automatically handed over to the next one. A small wireless LAN may only require a single access point; the number required increases as a function of the number of network users and the physical size of the network. Access points operate on Wi-Fi or on the more recently approved DECT standard.

Caller ID (CID)
The "called from" name and number that is transmitted and displayed over telephone lines. The caller has the ability to block delivery of this information by dialing 67 before dialing the destination number.

Hold
A business feature where a call is temporarily held by the KSU or Server and the caller typically hears music or an announcement during this time. Hold is used while sending the caller to another extension, while setting up a conference call, or while answering another call or simply when looking up information.

IP (Internet Protocol)
A protocol that specifies the way data is broken into packets and the way those packets are addressed for transmission. Unlike traditional telephone lines which create a straight path from caller to recipient; IP uses the best available path at any given moment to move data packets between point A & point B. The beauty of IP is that the sending end and receiving end communicate success in sending and receiving to insure all data packets are delivered. A really great concept of IP is that of self healing. If a route is broken and the data packets cannot be delivered an alternate route is automatically selected.

Speakerphone
A phone that has a microphone and a speaker that allows you to talk to your caller without lifting the handset. This is best used in private offices and when multi party conferencing is required. Never use a speakerphone in a noisy environment.

Transfer
This business feature allows an employee to send a call to another phone without having to announce the call first. This is the typical means for moving a call through a PBX phone system.
