Data Sheet
2.3.7
The SCOUT-DX provides several test and diagnostic functions for the transceiver:
2.3.7.1
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 TR_CONF.RLP (see chapter 7.2.3). The
2.3.7.2
Two kinds of test signals may be sent by the SCOUT-DX:
– The single pulses are of alternating polarity at 2 kHz (one pulse per frame). The
– 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.
data received from the line interface is looped back to the line interface. The D-
channel information received from the line card is transparently forwarded to the
downstream IOM-2 D-channel.
The downstream B-channel information on IOM-2 is fixed to ‘FF’
active.
corresponding C/I command is SSP (Send single pulses).
command is SCP (Send continuous pulses).
