17. The provision of telephone service over the Internet.






18. The process of making a disk partition available.






19. In the context of wireless signal propagation - the phenomenon that occurs when an electromagnetic wave encounters an obstruction and splits into secondary waves. The secondary waves continue to propagate in the direction in which they were split. Th






20. A type of antenna that issues and receives wireless signals with equal strength and clarity in all directions. This type of antenna is used when many different receivers must be able to pick up the signal - or when the receiver's location is highly m






21. On a network following the H.323 standard - a gateway that provides translation between network devices running H.323 signaling protocols and devices running other types of signaling protocols (for example - SS7 on the PSTN).






22. In LDAP naming conventions - the name of an object.






23. A LAN that uses wireless connections for some or all of its transmissions.






24. On a network following the H.323 standard - any node that provides audio - visual - or data information to another node.

35. A representation of a thing or person associated with the network that belongs in the NOS directory.






36. A protocol used between media gateway controllers and media gateways. It is poised to replace MGCP on modern converged networks - as it supports a broader range of network technologies - including ATM. Also known as H.248.






37. A type of wireless system in which the receiver can be located anywhere within the transmitter's range. This allows the receiver to roam from one place to another while continuing to pick up its signal.






38. The proprietary version of UNIX that comes from Bell Labs.






39. A protocol for communications and resource access between systems - such as clients and servers.






40. A Session layer call signaling protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for call or videoconference setup between nodes on a VoIP or video-over-IP network - indicating node status - requesting addit






41. A protocol that enables one system to access files on another system.






42. A Session layer control protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for controlling a session between two nodes. For example - it ensures that the two nodes are communicating in the same format.
