Data Sheet
2.3.8
The SCOUT-P(X) provides several test and diagnostic functions for the transceiver:
2.3.8.1
Two test loops allow the local or the remote test of the transceiver function.
– The local loop (test loop 3) which is activated by a C/I0 ARL command loops the
– The remote loop (test loop 2) is activated by the U
2.3.8.2
Two kinds of test signals may be sent by the SCOUT-P(X):
– The single pulses are of alternating polarity at 2kHz (one pulse per U
– The continuous pulses are pulses of alternating polarity. The corresponding C/I
transmit data of the transmitter to its receiver. The information of the IOM-2 upstream
B- and D-channels is looped back to the downstream B- and D-channels. The T-bit is
also transparent which means that the state of the BAC-bit is looped back to the S/G-
or A/B-bit.
data back to the U
is transparently forwarded to the downstream IOM-2 D-channel.
The downstream B-channel information on IOM-2 is fixed to ‘FF’
active. Additional to C/I0 a remote loop (loop 2) is indicated by the RLP bit in the
TR_STA register.
corresponding C/I command is SSP (Send single pulses).
command is SCP (Send continuous pulses).
