Black Box Explains...T1 channel banks.
T1 is a digital transmission method for multiplexing multiple voice and data channels over two pairs of wires.
By using a technique called Time-Division Multiplexing (TDM), T1 interleaves both voice and/or LAN data across DS0 subchannels. The primary benefit of T1 is bandwidth—1.544 Mbps—available in 24 easily allocated 64-kbps DS0 subchannels.
T1 sends data in frames made up of 24 eight-bit words (one word for each subchannel) and one framing bit for a total of 193 bits per frame. A T1 channel transmits 8000 frames per second.
The framing bits on successive frames follow a pattern for a superframe format. T1 channel banks check this pattern to make sure synchronization is maintained.
T1 is the most flexible end-to-end digital service option available today. It’s the preferred service for internetworking voice, data, fax, and video signals across an enterprise network.
