14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
With digital loopback activated, the transmit input data at TCLK/TPOS/TNEG is looped back to the receive
output data at RCLK/RPOS/RNEG. The digital loopback mode includes the Transmit JA (if enabled). The
receive input data at RTIP/RRING is ignored while valid transmit output data continues to be sent to the line. A
simplified block diagram of digital loopback is shown in Figure 21.
F
With dual loopback activated, the remote loopback is combined with the digital loopback. A simplified block
diagram of dual loopback is shown in Figure 22.
