PNT Private Network Termination

4.1PNT Private Network Termination

PNT converts the two-wire UP0 interface to the four-wire S0 interface and extends the range. This gives you the advantages of the S0 and S0 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.

4.2PNT E Private Network Termination

The PNT E converts the two-wire UP0/E interface to the S0 interface to connect up to two S0 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 S0 interface.

4.3PNT Q Private Network Termination

PNT Q converts the two-wire U2B1Q interface to the four-wire S0 interface and extends the range. This gives you the advantages of the S0 and S0 bus interfaces at great distances from

the Hicom system (connecting up to eight telephones and using fewer cables and system ports).

4.4Distance 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 (U2B1Q 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 U2B1Q interface (2-wire).

Distance Adapter M (multiple) - UCON M

UCON M is available via four 6-pin RJ 11 entry (4x U2B1Q) and exit interfaces (4x UP0/E). This adapter is used for connecting four telephones and their options.
