INSTALLATION INSTRUCTION
Subject responsible
The ISDN PART
DIP-switches position 154 to 157
Switch 1 selects the termination on the send side.
Switch 2 selects the termination on the receiver side.
Switches 3 and 4 enable remote power feeding to the
connected ISDN terminals. Switches 1...4 should be
set to ON if the link is set as S-interface .
Note: At the end of each line a termination resistor
must be installed (e.g. in the last wall outlet).
Switch position 42
When selecting S- or T-interfaces start by setting the
T-interfaces using switches 4, 3, 2 and 1 in consecutive
order then set the S-interfaces starting with switches 1,
2, 3 and 4.
Settings and ranges on the T-/S-interface

The VMU PART
The VMU functionality and the (4) registers are availa-
ble if the Compact Flash Card is inserted.
For installation and configuration refer to the stipula-
tions in document
Note: The VMU will not start up without the internal
directories created on the Compact Flash Card.
The unlock key (file named DISK.ULK) must be
valid on the compact flash card.
The MFU board can use only flash cards supplied by
ERICSSON. These flash cards are delivered with a
control file called DISK.ULK containing a licence key.
This file must not be opened by any tool as this would
distroy the file and thus disable the compact flash card.
This will cause an error condition indicated by slow
flashing yellow and green extension LEDs.
Limitations:
Only four MFU boards may be mounted per system.
MFU board(s) can be mixed with VMU-HD board(s)
but if a MFU board is installed, no VMU-D board may
be installed in the system.
If a MFU board is installed without compact flash card,
the complete VMU part is marked inactive. If later on
the MFU will be upgraded with a compact flash card,
then this can not be done by using the Hot swapping
feature, due to different card types. The MFU without
flash card has to be removed completely from the sys-
tem (from HW and SW point of view ) and then the
MFU with flash card can be included in the system.
The prevoius programming of the card, has to be done
again.
The ELU-D3 PART
The DBC 213 and DBC 214 instruments are not
supported with 4 key panels, only 2 key panels per
instrument are allowed to be connected.
