10.43.1. Feature Description 
To connect standardized S0 telephones to the UP0E interface of the
SLMO, use the "UP0E to S0" adapter box PNT E. This allows you to operate
S0 telephones on the UP0E interface of the SLMO.
The OpenScape 4000 Administration does not recognize the PNT E. Configure
it like an optiset E telephone, making sure that there is enough DTISO
DIMEN memory.
When you make an OPTIDAT request using AMO SBCSU, you will not find
an PNT E; the PNT E reports as an "optiset E basic".
IMPORTANT:
You can connect a maximum of two reporting sources
(Telephones with S0 interfaces that conform to the ITU Recommendation
I.430 or Q920/921).
IMPORTANT:
In place of an optiset E telephone as representative
for PNT E, you can also configure an optiPoint 500 (DVCFIG=OPTIP500),
which the system then automatically changes into an optiset E.
IMPORTANT:
To supply the S0 telephones without a separate
power supply, you need an additional power supply unit.
