T lines are designed for Digital data how they can be used for Analog Transmission?



  • DS-1 requires 8 Kbps of overhead 
  • To understand this overhead, let’s examine format of a 24-voice channel frame o Frame used on T-1 line is usually 193 bits divided into 24 slots of 8 bits each + 1 bit for synchronization (24*8+1=193) 
  • 24 segments are interleaved in one frame 
  • If a T-1 carries 8000 frames, the data rate is 1.544 Mbps (193 * 8000=1.544 Mbps) which is capacity of the line
