For internal use only

HiPath 3000 System Overview

HiPath 3550

● MPPI (music on hold)

Interfaces

● Eight U

P0/E

(digital subscriber line interfaces)

In HiPath 3000 V1.2 and later 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)

● V.24 interfaces

First V.24 interface on the CBCC; the second interface is implemented using the V24/1 op-

tion.

2.4.3.2 UPSC-D

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 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 power supply (see

Section 2.4.6). For this, the EPSU2’s DC connection needs to be connected to the special –

48 Vdc input on the UPSC-D. The UPSC-D’s internal -48-V output is deactivated when the ex-

ternal power supply is connected.
