1 data channel
"A separate channel of an Integrated Services Digital Network (ISDN) line that is used for ISDN signaling. For ISDN Basic Rate Interface (BRI), the D-channel is 16 kilobits per second (Kbps). For ISDN Primary Rate Interface (PRI), the D-channel is 64 Kbps." -
2 PRI
"One of two ISDN transmission rate services (the other is the basic rate interface, BRI). PRI has two variations. The first, which operates at 1.536 Mbps, transmits data over 23 B channels and sends signaling information at 64 Kbps over one D channel in the United States, Canada, and Japan. The second, which operates at 1.984 Mbps, transmits data over 30 B channels and sends signaling information at 64 Kbps over one D channel in Europe and Australia." -
3 Resource Reservation Protocol
A signaling protocol that allows the sender and receiver in a communication to set up a reserved highway for data transmission with a specified quality of service.English-Arabic terms dictionary > Resource Reservation Protocol

4 RSVP
A signaling protocol that allows the sender and receiver in a communication to set up a reserved highway for data transmission with a specified quality of service. -
5 wireless LAN
"A local area network (LAN) that sends and receives data via radio, infrared optical signaling, or some other technology that does not require a physical connection between individual nodes and the hub. Wireless LANs are often used in office or factory settings where a user must carry a portable computer from place to place."
