DIAGNOSTICS
The DS3150 contains an onboard Pseudo Random Binary Sequence (PRBS) generator and detector. This
function is useful in testing the device at the physical layer. It will generate and detect either a 215 – 1
(T3 or STS-1) or 223 – 1 PRBS according to the ITU O.151 specification. The PRBS pattern generated
and detected by the DS3150 is an unframed pattern. In other words, no T3, E3, or STS-1 framing
patterns are inserted in the transmit data stream nor expected in the received data stream. The PRBS
generator is enabled via the TDS0 and TDS1 inputs. See Tables 2A and 2B for details. The PRBS
detector is always enabled and will report it’s status via the PRBS output if signal EFE = 1. When the
PRBS detector is out of synchronization, the PRBS output will be forced high. When the PRBS detector
synchronizes to the incoming pseudorandom pattern, the PRBS output will go low and then pulse high for
each bit detected in error. See Figures 1F and 1G. On the receive side, the recovered data is
B3ZS/HDB3 decoded before it is routed to the PRBS decoder.
The DS3150 also has two internal loopbacks that can be used for testing. See Figure 1A. The Analog
Loopback loops the outgoing transmit waveform back to the receiver. When this loopback is enabled,
data will be transmitted as it normally would be and the incoming data at RX+ and RX– is ignored. The
Remote Loopback loops data from the receive side to the transmit side. When this loopback is enabled,
data will continue to pass through the receive side as it normally would and data at the TPOS and TNEG
inputs is ignored. These two loopbacks are invoked via the LBKS* input. See Table 2A.
