Interfaces
● Eight U
P0/E
(digital subscriber line interfaces)
Up to seven BS3/1 base stations can be connected directly for HiPath Cordless Office.
● Four T/Rs (analog subscriber line interfaces)
For Australia only: The T/R interfaces supply a ring voltage of 35 V
eff
. Depending on the
terminals connected, we cannot exclude the possibility of errors occurring during ringing
state.
● Two S

interfaces (trunk or subscriber or fixed connection)
● One V.24 interface
2.9.3.2 UPSC-DR
Introduction
This board combines the power supply and battery management functions. No other compo-
nents are required if operated as a power supply. To maintain short-term battery emergency
operation after a power failure, that is, to use uninterruptible power supply functions, you must
also connect a battery pack.
An EPSU2-R external power supply must be used if the total number of U
P0/E
stations, analog
stations, and stations connected using adapters is greater than 72.
Additional power can be made available by connecting the external EPSU2-R power supply
(see Section 2.9.6) To do this, connect the DC port on the EPSU2-R to the special –48 Vdc in-
put on the UPSC-DR. The UPSC-DR’s internal -48-V output is deactivated when the external
power supply is connected.
