GENERAL
DS3 NIU MTC
This job aid provides instructions for using the ADTRAN DS3 NIU Monitor
P/N 1212071L1
and Test Card (DS3 NIU MTC) to provide a quick, reliable means for craft
CLEI: NCC1SN0D
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
NIU3
♦
DS3 NIU 12-Slot Shelf

Digital Network Loopback Test
The DS3 MTC inserts into any empty slot in the DS3 NIU chassis desig-
NTWK TO CUST
MON nated for test. There are six front panel midsize connectors labeled as shown:
♦ NTWK TO CUST MON
♦
OUT FROM NTWK
OUT FROM
♦ IN TO NTWK
NTWK
♦ CUST TO NTWK MON
♦
OUT FROM CUST
♦ IN TO CUST
IN TO NTWK
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
CUST TO NTWK
transmission into the respective loop. The MON jacks monitor the network-
MON
to-customer or customer-to-network loop.
A green ONLINE status LED verifies that the card has ±24 VDC or
OUT FROM –48 VDC applied, and the cut-through relays are energized. If the LED is
CUST
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.
IN TO CUST
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.
