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... more/see it nowLAN 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. And Black Box is your supplier of T1 hardware with a broad range of solutions for consolidating your global high-speed network management. collapse
