ISDN H-Channel

In Integrated Services Digital Network (ISDN), the H-Channel is used for high-speed data transmission.

It is designed to provide higher bandwidth compared to B (Bearer) channels, accommodating services that require faster data rates.

H-Channels are categorized into different types based on their capacities:

  • H0 Channel: Offers a data rate of 384 kbps, which is created by aggregating six B-Channels.

  • H10 Channel: Provides a data rate of 1472 kbps, achieved by aggregating 23 B-Channels.

  • H11 Channel: Has a data rate of 1536 kbps, similar to the primary rate interface in North America.

  • H12 Channel: Offers a data rate of 1920 kbps, used primarily in Europe.

These channels are primarily used for applications that demand substantial data throughput, such as high-quality video conferencing and large data transfers.
