PART I QUICK START: INTRODUCTION & INSTALLATION
The NCT-1000 & NCT-1020 are IP DSLAMs designed for MTU/MDU/MHU applications. They provide data,
voice, and video services over existing copper telephone wires. Carriers and service providers can utilize the
NCT-1000/NCT-1020 to offer high-speed Internet access to tenants of high-rise buildings without rewiring
the building. By using Digital Subscriber Line technology, the NCT-1000/NCT-1020 provides a cost-effective
and scalable infrastructure to meet the requirements of a wide range of building tenants.
The NCT-1000/NCT-1020 allows multiple interchangeable DSL channel units to coexist in the same shelf
and it has up to two 10/100/1000M WAN Ethernet ports to concentrate the traffic on an IP network. This
makes the NCT-1000/NCT-1020 a flexible solution for deployment in high-rise buildings, communities,
campuses, or hospitals.

Power Supply Connectors
Warning: For initial setup, before you supply power to the shelf, it is suggested not to insert any
card into the shelf. Only insert the card after the shelf power connectors are appropri-
ately assembled, and the power LED should be lit green.
There are two DC-48V power source inputs, labeled A and B. You can verify the power states of these two
power sources (connected or disconnected) from the front panel LED indicators, PWRA and PWRB.
The power supply connectors can connect to the DC input or connect to the AC input with an additional
AC/DC power supply.
PG PIN: Connect to ground of +48VDC power supply source (positive polarity).
-48VDC PIN: Connect to -48VDC power supply source (negative polarity).
FG PIN: Connect to Earth ground.
Note: The pin location sequence on the power connectors for the CT-1020 and CT-1000 are
different. From left to right, the NCT-1020 power connector pin signals are FG, PG, -48V;
the CT-1000 are: -48V, PG, FG.
Power Ground & Frame Ground (GND/FG)
The Power Ground (PG) and Frame Ground (GND) are provided.
Fuses: FUSE A & FUSE B
FUSE A and FUSE B are used to guarantee that the system power is supplied appropriately via the power
connectors. When an over-current condition occurs, the fuse will blow. When it happens, the maintenance
personnel should replace the defective fuse.
The fuse for the NCT-1020 is 10A and for the NCT-1000 is 20A.

2.3 Install the Card
1. Insert the card into the shelf and tighten its screws of the card.
2. Connect the centronic-50 cable to the card and drive the screws of bracket on the centronic-50 cable
tightly with shelf. If you want to replace the card on shelf, you only need to remove the card and re-
insert the card into the same slot. It is not necessary to remove the centronic-50 cable, already fixed to
the shelf.
Note: If the port link is unstable or fails, check to ensure that the rear panel bracket is fixed.
