Note: 40 V can also be supplied on connector T3 (connect the 40 V supply unit to connector
T3, and the base station to connector S3).
4.4.2 Switch settings
CA1.1 to CA1.4 (ADAPT) : these switches are used for line adaptation. Leave these switches on
the setting ON (factory setting).
CA2
: the CA2 switch (located on the copper side) is used to configure synchronization
(T0) and master or slave mode (S0).
For LD4 RJ in T0
For LD4 RJ in S0 (for DECT base stations)
Table 7: Description of switches CA2.1 and CA2.2 on the LD4 RJ card
SW1 : this jumper is not used, leave in position 1-2.
SW3 , SW4 , SW5 , and SW6 : these jumper switches are used to disable each interface's remote
power supply when a T0 interface is connected.

CA2.1 SWITCH EXPLANATION
ON Leave set to ON position. If the LD4 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, CA2.1 has no effect. The
synchronising positions in an XL cabinet are the locations 1-00 to 1-05. For
an XS cabinet, all positions are synchronising. On XS12, the backplane
does not transmit the network synchronisation (synchronising slots are T0
interfaces built into the UCT card).
OFF Do not set it to OFF position (in OFF position, the ISDN clock is not taken
as reference, whatever the slots).
SWITCH CA2.2 EXPLANATION
M Position not allowed
S Slave LD4 RJ: To be set to position S on all LD4 RJ cards (LD4 RJ card
always slave).
SW3 Remote power supply for interface 3
SW4 Remote power supply for interface 2
SW5 Remote power supply for interface 1
SW6 Remote power supply for interface 0
