DataScout 10G & 10Gx
CSU/NIU Emulation – Tap on CSU/NIU Emulate to configure the test set to respond to
CSU, NIU-4, and NIU-5 (Smart Jack) loopbacks. Upon reception of a loopback the
system will beep and display (at the bottom) "**loopback activated**" and the type of
loopback detected (e.g. NIU-5 loopback activated!). In a loopback mode the
DataScout 10G recovers the RCV data and loops it to the TX. You must first configure
the DataScout 10G for DS1 TERM and then CSU/NIU Emulate. The clocking should
be NW (looped-timed) for this mode.
Signaling Bits – Tap Signaling Bits to select the Signaling Bits to display all 24 DS0
channels in of DS1-A and DS1-B on one screen. This first bit is A then B, C, D.
PCM Voice – When the DST-SW-V option is enabled the test set can emulate Loop-
Start (LS), Ground-Start (GS), DID and E&M circuit (IMM and Wink) from in both CO
and PBX (Station) modes.
DS0 Frequency & Level – Select PCM Voice (under TERM/Monitor button) followed
by the DS0 channel (1-24) that you would like to measure frequency and loss. Note the
frequency is displayed in Hz +/- 2Hz and the level in dBm0 +/- .5dB. The digital data
content (Bit 1 through 8) is also displayed under F&L. along with the hexadecimal
equivalent to the binary bit 1-8 value. To exit DS0 Freq/Level (PCM Voice) tap on DS0
channel # and select OFF.
DS0 Data – This option is used for DS0 BERTS and TX/RX DDS control code. To
activate select the DS0 channel pull-down (left of DS0 Data). The DataScout 10G dis-
plays the TX and RX data content along with the hexadecimal equivalent to the binary
bit 1-8 value.
Fractional T1 – Select this mode to test contiguous and noncontiguous DS0's
(Nx56/64K). Select FT1 select under the Monitor/TERM pull down menu (use finger to
scroll down) then tap on a desired channel or all desired channel numbers. You can
BERT on the selected channels and perform a BER as well.
Drop & Insert – Requires the DST-SW-DT1 dual port DS1 option. Tap on the DROP
& INSERT to drop the DS1-A test side and insert from the DS1-B bypass side. When
you select DROP & INSERT mode a sequence of screens prompt you how to the
properly setup and configure the system. One of these setup screens provide a block
diagram of which side is the test-side and which is the bypass and how to correctly
patch into the circuit.
DS1 TERM (-7.5, -15, -22.5dB) – Selecting any of these options will activate terminate
mode with the transmit level set to the selected value +/- 2db.

Clock Settings

NW Network Timed – When this mode is selected the test set recovers the clock tim-
ing from the received signal. NW is the default initial setting.
