In the [[Integrated Services Digital Network]] (ISDN), a high-speed [[communication channel]] comprising multiple aggregated low-speed channels to accommodate [[Bandwidth (signal processing)|bandwidth]]-intensive applications such as [[file transfer]], [[videoconferencing]], and high-quality audio. An H channel is formed of multiple bearer [[B channel]]s bonded together in a primary rate access (PRA) or [[primary rate interface]] (PRI) frame in support of applications with bandwidth requirements that exceed the B channel rate of 64&nbsp;kbit/s. The channels, once bonded, remain so end-to-end, from [[transmitter]] to receiver, through the ISDN network. The feature is known variously as multirate ISDN, Nx64, channel aggregation, and [[Channel bonding|bonding]].
H channels are implemented as:
* H0  = 384&nbsp;kbit/s(6 B channels)
* H10 = 1472&nbsp;kbit/s(23 B channels)
* H11 = 1536&nbsp;kbit/s(24 B channels)
* H12 = 1920&nbsp;kbit/s(30 B channels) – International ([[E-carrier]]) only.
