Wall mounting
The NT1+2a/b unit is designed for wall mounting. The diagrams in figure 1, figure 2
and figure 3 show the connections to be made for the NT1+2a/b unit.
Mount the NT1+2a/b close to the transmission cable of the telecommunications
operator. In addition, you will need a mains socket for the line cord (max. 2 m long).
CAUTION: Before defining the position of the drill holes make sure that there
are no other concealed installations, e.g. water pipes, electrical power cables
etc.
Mark the drill holes on the intended place of the wall. After drilling the holes
(
∅
6 mm) and inserting the dowels, screw the 3.5 mm round-head screws into the
wall as far as the distance between wall and screw head is only approx. 2 mm. Hang
the NT1+2a/b over the screw heads and pull it down until it locks safely in its place.
IMPORTANT: Do not permanently expose the NT1+2a/b to the sun! Please keep
it dry!
Connecting the NT1+2a/b to the ISDN line (U interface)
A RJ11 connector is available to connect the U interface directly. The position of the
U interface connector is shown in figures 2 and 3.
Connecting the termination units
Connect your analogue terminal equipment
, e.g. DTMF telephone, fax, etc. to the
RJ11 connectors situated in the middle of the housing base or, alternatively, the
connectors for a/b1 and a/b2 directly beside the RJ11 modular jacks where block
wiring has been provided (Pins 3 and 4 are used in the RJ11 connector).
Connect the ISDN terminal equipment by inserting the appropriate plug into the
RJ45 communication outlets on the right-side base of the NT1+2a/b. The 4 wire
clamp connectors for bus installation at S/T interface are described in figure 1, so
that wires for receive and transmit directions would not be mixed up.
Power supply
Now connect the 230 V a.c mains supply. Before switching on the 230 V a.c mains
supply, please check that all other connections are correct and secured.
The installation is now complete.
