Switch Settings - Aastra X series Installation And Implementation Manual

4.6.2 Switch settings

Note: The Master/Slave micro-switch of the previous LD4 cards no longer exists. The LD4NX
RJ card is always in DECT slave mode; it cannot generate the DECT clock.
The LD4NX RJ card has no micro-switch for downloading the flash memory with a BOF3
type tool (automatic detection).
Micro-switch CA1 (HVAL) is used to configure synchronisation (T0).

Jumpers J1_1, J1_2, J1_3 and J1_4 are used to enable the remote power supply (40 V or

• J1_1: Remote power supply for interface 0
• J1_2: Remote power supply for interface 1
• J1_3: Remote power supply for interface 2
• J1_4: Remote power supply for interface 3
Note: J2_1, J2_2, J2_3 and J2_4 are storage positions for jumpers.
A jumper positioned on SW5 or SW6 is used to select the 40V or 48V remote mains supply.
•
• Jumper positioned on SW5 (factory position) is used to select the 48V power supply.
• Jumper positioned on SW6 is used to select the 40V power supply.
Note: The status of remote power supply jumpers and synchronisation of an LD4NX RJ card in
LD4X mode can be displayed by MMC (menu 3-2-4, "Status of ISDN card jumpers", see
Figure 4-18:).
• Jumper J14 is used to select the (LD4N or LD4X) card's operating mode:
• Leave the jumper in factory position 2-3 for an LD4N configuration.
• Place the jumper on 1-2 or remove the jumper for an LD4X configuration allowing the
use of additional functions.

Leave set to ON position. If the LD4NX RJ card is fitted in a
synchronising slot, the ON position allows the PBX to take the ISDN
network clock as reference clock. In a non-synchronising slot, CA1
has no impact. The synchronising positions in an XL cabinet are slots
1-00 to 1-05. For an XS cabinet, all positions are synchronising.
For an XS12 cabinet, the back plane does not send network
synchronisation (synchronising positions are the T0 interfaces
integrated into UCT).
Do not set it to OFF position (in OFF position, the ISDN clock is not
taken as reference, whatever the slots).
