GENERAL
This job aid provides instructions for using the ADTRAN DS3 NIU Monitor
and Test Card (DS3 NIU MTC) to provide a quick, reliable means for craft
personnel to monitor and test both the network side and customer side data
loops. The DS3 MTC is compatible with any DS3 NIU3 chassis:
♦DS3 NIU Single Slot Housing
♦DS3 NIU 3-Slot Shelf
♦DS3 NIU 12-Slot Shelf
Digital Network Loopback Test
The DS3 MTC inserts into any empty slot in the DS3 NIU chassis desig-
nated for test. There are six front panel midsize connectors labeled as shown:
♦NTWK TO CUST MON
♦OUT FROM NTWK
♦IN TO NTWK
♦CUST TO NTWK MON
♦OUT FROM CUST
♦IN TO CUST
The OUT FROM X test jacks receive network or customer data entering the
DS3 MTC and pass that data to the test device. The IN TO X test jacks inject
network or customer test signals from the test device into the DS3 MTC for
transmission into the respective loop. The MON jacks monitor the network-
to-customer or customer-to-network loop.
A green ONLINE status LED verifies that the card has ±24 VDC or
–48 VDC applied, and the cut-through relays are energized. If the LED is
off, the card does not have power, and the cut-through relays are de-ener-
gized. Cut-through relays are mounted separately on the housing, not on the
DS3 MTC.
The DS3 MTC is not intrusive during monitoring functions but is intrusive
and will disrupt data flow during testing functions.
INSTALLATION
After unpacking the unit, inspect it for damage. If damage is noted, file a
claim with the carrier, and then notify ADTRAN. See Warranty section.
Insert the card in the empty slot designated for test. Ensure the edge connec-
tor seats firmly into the backplane. Secure the card in place with the thumb-
screws.

DS3 NIU Monitor and Test Card
DS3 MONITOR AND TEST CARD OPERATION
The DS3 NIU MTC can pass both network and customer signals up to 450 feet. See illustra-
tion below. During normal operation, IN TO NTWK is internally connected to OUT FROM
CUST, and IN TO CUST is internally connected to OUT FROM NTWK. During test func-
tions the intrusive jack inserted into the DS3 MTC breaks the internal connection with its
corresponding jack and automatically terminates it at 75 ohms. In the tests described below
the test jacks inserted into the DS3 NIU MTC access the NIU3 backplane jacks for the net-
work or customer loops.
