bonding - technical definition
- The process or method of permanently joining the metallic shields, screens, or armor of multiple wire and cable segments in order to establish electrical continuity between them, to a ground strap or wire that connects to a ground rod, and eventually to ground. Bonding serves to ensure that electrical noise will be conducted to ground, rather than coupling with and, therefore, interfering with the desired signal.
- Synonymous with channel aggregation, dynamic bandwidth allocation, multirate ISDN, and Nx64. A feature of ISDN-compatible terminal adapters (TAs), PBXs, and routers that enables the system to dynamically allocate, or bond, multiple contiguous 64-kbps bearer (B) channels to serve an application that requires more than a narrowband channel. From the transmitter, through the network, and to the receiver, the narrowband channels are bonded and treated as a single superrate channel known as a high-speed (H) channel. As an example, a videoconference might require 128 kbps (2 channels) or 384 kbps (6 channels). Dial-up Internet access typically benefits from bonding two channels for a connection at 128 kbps. Also, multiple IP, ATM, or frame relay links can be joined to emulate a faster channel. See also B channel, H channel, ISDN, narrowband, PBX, router, superrate, and TA.
