PNT Private Network Termination
4.1 PNT Private Network Termination
PNT converts the two-wire U
P0
interface to the four-wire S
0
interface and extends the range.
This gives you the advantages of the S
0
and S
0
bus interfaces at great distances from the Hi-
com system (connecting up to eight telephones and using fewer cables and system ports).
The desktop model can also be mounted on the wall. Power is supplied by an optiset E local
power supply unit.
4.2 PNT E Private Network Termination
The PNT E converts the two-wire U
P0/E
interface to the S
0
interface to connect up to two S
0
terminals (such as a PC and fax) to Hicom.
A local power supply is available for the PNT E if the connected devices need to receive power
from the S
0
interface.
4.3 PNT Q Private Network Termination
PNT Q converts the two-wire U
2B1Q
interface to the four-wire S
0
interface and extends the
range. This gives you the advantages of the S
0
and S
0
bus interfaces at great distances from
the Hicom system (connecting up to eight telephones and using fewer cables and system
ports).
4.4 Distance Adapter (UCON S and M) at Hicom 300/300 E and HiPath
4000
Distance adapters increase the optiPoint 500 telephone range from 1,000 m to a total of 8,000
m, depending on the cable type. The range between the optiPoint 500 distance adapter and
telephone is limited to 100 m (depending on the cable type and diameter).
To connect this adapter, an SLMQ line card (U
2B1Q
interface, 16 ports) with LAP-S and CorNet-
TS must be provided in Hicom 300/300 E.
Power is supplied to the distance adapter via a local power supply unit. An 8-pin RJ 45 plug is
used as the mains power supply. This is the same as the plug used for PNT.
The stacked UCON S or M housing is suitable for desktop installation or mounting on the wall.
Distance Adapter S (single) - UCON S
UCON S has a 6-pin RJ 11 entry and exit port. It serves as the connection between an optiPoint
500 telephone and its options via the U
2B1Q
interface (2-wire).
Distance Adapter M (multiple) - UCON M
UCON M is available via four 6-pin RJ 11 entry (4x U
2B1Q
) and exit interfaces (4x U
P0/E
). This
adapter is used for connecting four telephones and their options.
